Brad King 42bb42d197 VS: Always initialize CMAKE_CONFIGURATION_TYPES in IDE generators
Initialize the CMAKE_CONFIGURATION_TYPES cache entry early during
EnableLanguage like the Xcode generator does.  Avoid depending on
the MSVC compiler information module to do it.  Otherwise code like

  project(MyProj NONE)

sets CMAKE_CONFIGURATION_TYPES late (in GenerateConfigurations), and
to only "Debug" and "Release" instead of the standard set of 4.

Brad King f9eee7f183 Windows: Search '/' prefix only when cross compiling (#10994)
Commit dac78148 (...makes the mingw cross compiler work out of the
box..., 2007-08-02) added to CMAKE_SYSTEM_PROGRAM_PATH and
CMAKE_SYSTEM_LIBRARY_PATH paths like "/bin" and "/lib" with no Windows
drive letter so that cross-compiling to Windows from Linux would search
these paths under CMAKE_FIND_ROOT_PATH.  Later commit 2a782880 (...use
CMAKE_SYSTEM_PREFIX_PATH when possible, 2008-01-16) generalized this
approach by instead adding "/" to CMAKE_SYSTEM_PREFIX_PATH.

Both commits assumed that the paths would never match anything on
Windows hosts without a drive letter.  However, Windows evaluates these
paths relative to the current working drive letter so find_* commands
may report paths like "/lib/..." when paths like "c:/lib/..." exist on
what happens to be current drive.  Such drive-less paths are not
reliable when the working drive changes, so we should not use them.

Fix WindowsPaths.cmake to add '/' to CMAKE_SYSTEM_PREFIX_PATH only when
cross-compiling to Windows from a non-Windows host.  This will avoid
searching and finding local paths without a drive letter on Windows.

Brad King fb9f73de64 MSVC: Invoke 'link' directly for executables
Update the CMAKE_<LANG>_LINK_EXECUTABLE rule variable to invoke the
linker directly instead of through the compiler.  We already do this
for DLL linking with CMAKE_<LANG>_CREATE_SHARED_LIBRARY.

This also works around a VS 6 cl bug.  While invoking the link tool
internally it fails to correctly quote flags like /pdb:... with spaces
in the value.

Brad King 42ba1b08f3 VS: Separate compiler and linker PDB files (#11899, #14062)
The MS tools create two types of PDB files as explained here:

 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.71%29.aspx
 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.80%29.aspx
 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.90%29.aspx
 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.100%29.aspx

One is created by the compiler (/Fd) and the other by the linker (/pdb).
The two options should not specify the same file.  Split them up.

In the VS IDE generators, simply drop ProgramDataBaseFileName to
take the VS default "/Fd$(IntDir)vc$(PlatformToolsetVersion).pdb".

In the Makefile generators, set "/Fd" on the compile line to be
the directory containing object files (with a trailing slash the
compiler will add the "vc$(PlatformToolsetVersion).pdb" filename
automatically).  Drop the /Fd option from the exe link command
line and add "/pdb" instead (already done for dll linking).
Update these rules for both MSVC and Intel tools.

Drop support for PDB_OUTPUT_DIRECTORY and PDB_NAME in STATIC
libraries because the generated .pdb files are only from /Fd
and not real linker-generated .pdb files.  Update documentation to
clarify that the PDB_* properties are only for linker .pdb files.

This regresses the PDBDirectoryAndName test for STATIC libraries.
Since it is not clear at this time what should be done for STATIC
library .pdb files, comment out the relevant portion of the test
and leave a TODO comment.

Brad King bce7a2a3a5 AIX: Do not use -brtl to create shared libraries (#13997)
The flag was added incorrectly by commit 9c3a6eb4 (Need -brtl when creating
shared libraries, 2003-05-16).  According to "man ld" the -G option implies
"-brtl -bnortllib ...", -brtl implies "-brtllib", and -brtllib should only be
used for executables, not shared libraries.  Therefore it is incorrect and
unnecessary to specify -brtl explicitly after -G.

Brad King baa33acbda AIX-GNU: Put implicit link directories in runtime libpath (#13909)
The GNU compiler front-ends on AIX invoke the linker with flags of the
form "-L/path/to/gnu/runtime/lib" to tell ld where to find the language
runtime libraries.  They depend on the default libpath behavior
documented in "man ld" to add the -L paths also to the runtime libpath
so the dynamic loader can find the language runtime libraries.  This
differs from platforms whose linkers have distinct -rpath flags that
non-system compilers can use to tell the dynamic loader where to find
their language runtime libraries.

Since commit 96fd5909 (Implement linking with paths to library files,
2008-01-22) CMake always passes "-Wl,-blibpath:" followed by any
project-defined RPATH plus "/usr/lib:/lib" in order to explicitly set
the runtime libpath and avoid getting all the project -L paths in the
runtime libpath.  The explicit libpath prevents the GNU compiler runtime
library -L paths from being placed in the libpath and then the dynamic
loader fails to find the language runtime libraries.

CMake already detects the implicit link directories for each language
since commit 07ea19ad (Implicit link info for C, CXX, and Fortran,
2009-07-23).  Add the implicit link directories to the explicit runtime
libpath for GNU compilers on AIX to fix this use case.

Brad King 188b0e9e37 Embarcadero: Fix default link stack/heap flags (#13912)
Since commit c70beb4b (change the default borland stack size, 2003-05-05),
commit 1b572eb9 (remove -H flags, 2003-05-08), and commit 2d411398 (Stack size
in generated programs should be 10 meg, 2003-06-12) CMake adds link flags to
select a 10MB stack.  At the time this was for consistency with our behavior on
MS, but that was recently removed by commit 51af1da3 (Remove "/STACK:10000000"
from default linker flags, 2012-11-23).

Change our Embarcadero link flags to select the default stack and heap settings
according to the compiler documentation.  This is more reliable than leaving
the flags out completely as it has been reported that the linker does not
always use its documented defaults.

Brad King cc676c3a08 OS X: Detect implicit linker framework search paths
Previously we hard-coded a list of implicit framework directories but
did not account for CMAKE_OSX_SYSROOT or for changes to the list across
OS X versions.  Instead we should automatically detect the framework
directories for the active toolchain.

The parent commit added the "-Wl,-v" option to ask "ld" to print its
implicit directories.  It displays a block such as:

 Framework search paths:
	/...

Parse this block to extract the list of framework directories.

Detection may fail on toolchains that do not list their framework
directories, such as older OS X linkers.  Always treat the paths

 <sdk>/Library/Frameworks
 <sdk>/System/Library/Frameworks
 <sdk>/Network/Library/Frameworks # Older OS X only
 /System/Library/Frameworks

as implicit.  Note that /System/Library/Frameworks should always be
considered implicit so that frameworks CMake finds there will not
override the SDK copies.

Brad King 2dd67c7ea0 OS X: Detect implicit link directories on modern toolchains
We detect the implicit link directories for the toolchain by adding a
flag to get verbose output from the compiler front-end while linking the
ABI detection binary.  Newer OS X toolchains based on Clang do not add
the implicit link directories with -L options to their internal
invocation of "ld".  Instead they use a linker that comes with the
toolchain and is already configured with the proper directories.

Add the "-Wl,-v" option to ask "ld" to print its implicit directories.
It displays them in a block such as:

 Library search paths:
	/...

Parse this block to extract the implicit link directories.

While at it, remove the checks introduced by commit efaf335b (Skip
implicit link information on Xcode, 2009-07-23) and commit 5195a664
(Skip implicit link info for multiple OS X archs, 2009-09-22).  Discard
the non-system link directories added by Xcode.  Discard all detected
implicit libraries in the multi-architecture case but keep the
directories.  The directories are still useful without the libraries
just to suppress addition of explicit -L options for them.

David Cole 51af1da3d2 CMake: Remove "/STACK:10000000" from default linker flags (#12437)
Modern apps that use multiple threads do NOT want 10 Megabytes of RAM
per thread being used for each thread's stack... Just leave off the
/STACK: argument, and let the compiler use a reasonable default value
for the stack size.

If existing single-threaded apps require the /STACK: argument because
they do need a very large stack size, they can add the flag in their
own CMakeLists files.

Brad King cd739794d6 MSVC: Drop default use of /Zm1000 for VS >= 7.1
From the option documentation of VS >= 7.1:

 "In earlier versions of Visual C++, the compiler used several discrete
  heaps, and each had a finite limit. Currently, the compiler dynamically
  grows the heaps as necessary up to a total heap size limit, and requires
  a fixed-size buffer only to construct precompiled headers. Consequently,
  the /Zm compiler option is rarely necessary."

Brad King 7195aca54f Make platform information files specific to the CMake version
At the top of a build tree we configure inside the CMakeFiles directory
files such as "CMakeSystem.cmake" and "CMake<lang>Compiler.cmake" to
save information detected about the system and compilers in use.  The
method of detection and the exact results store varies across CMake
versions as things improve.  This leads to problems when loading files
configured by a different version of CMake.  Previously we ignored such
existing files only if the major.minor part of the CMake version
component changed, and depended on the CMakeCache.txt to tell us the
last version of CMake that wrote the files.  This led to problems if the
user deletes the CMakeCache.txt or we add required information to the
files in a patch-level release of CMake (still a "feature point" release
by modern CMake versioning convention).

Ensure that we always have version-consistent platform information files
by storing them in a subdirectory named with the CMake version.  Every
version of CMake will do its own system and compiler identification
checks even when a build tree has already been configured by another
version of CMake.  Stored results will not clobber those from other
versions of CMake which may be run again on the same tree in the future.
Loaded results will match what the system and language modules expect.

Rename the undocumented variable CMAKE_PLATFORM_ROOT_BIN to
CMAKE_PLATFORM_INFO_DIR to clarify its purpose.  The new variable points
at the version-specific directory while the old variable did not.

Brad King af42ae4f81 Watcom: Simplify compiler version detection (#11866)
Since commit c198730b (Detect Watcom compiler version with its id,
2011-12-07) the CMAKE_(C|CXX)_COMPILER_VERSION variables are set for the
Watcom compiler.  Use these in Windows-wcl386.cmake to set the old
WATCOM1* version variables.  This avoids using the old EXECUTE_PROCESS
command which failed due to extra quotes anyway.

Brad King 7e58e5bb68 Prefer generic system compilers by default for C, C++, and Fortran
Teach CMake to prefer the system default compiler automatically when no
compiler is specified.  By default use "cc" for C, "CC" for C++, and
"f95" for Fortran.  Load a new Platform/<os>-<lang>.cmake module to
allow each platform to specify for each language its system compiler
name(s) and/or exclude certain names.

Create Platform/(CYGWIN|Darwin|Linux|Windows)-CXX.cmake modules to
specify "c++" as the system C++ compiler name for these platforms.  On
systems that use case-insensitive filesystems exclude C++ compiler names
that are distinguished from C compiler names only by case.

This will change the default compiler selection for existing build
scripts that do not specify a compiler when run on machines with
separate system and GNU compilers both installed in the PATH.  We do not
make this change in default behavior lightly.  However:

(1) If a given build really needs specific compilers one should specify
    them explicitly e.g. by setting CC, CXX, and FC in the environment.

(2) The motivating case is to prefer the system Clang on newer OS X
    systems over the older GNU compilers typically also installed.  On
    such systems the names "cc" and "c++" link to Clang.  This is the
    first platform known to CMake on which "c++" is not a GNU compiler.
    The old behavior selected "gcc" for C and "c++" C++ and therefore
    chooses GNU for C and Clang for C++ by default.  The new behavior
    selects GNU or Clang consistently for both languages on older or
    newer OS X systems, respectively.

(3) Other than the motivating OS X case the conditions under which the
    behavior changes do not tend to exist in default OS installations.
    They typically occur only on non-GNU systems with manually-installed
    GNU compilers.

(4) The consequences of the new behavior are not dire.  At worst the
    project fails to compile with the system compiler when it previously
    worked with the non-system GNU compiler.  Such failure is easy to
    work around (see #1).

In short this change creates a more sensible default behavior everywhere
and fixes poor default behavior on a widely-used platform at the cost of
a modest change in behavior in less-common conditions.

In almost all cases, this means duplication of the

assumed pie equivalent for the _PIE case.  Note that the GNU compiler
has supported -fPIE since 3.4 and that there is no -fPIC on GNU for

There is a possibility that the _PIE variables are not correct.
However, as there is no backwards compatibility to be concerned about
(as the POSITION_INDEPENDENT_CODE property is not used anywhere yet),
the current state suffices.

Modestas Vainius e1409ac59b Support building shared libraries or modules without soname (#13155)
Add a boolean target property NO_SONAME which may be used to disable
soname for the specified shared library or module even if the platform
supports it.  This property should be useful for private shared
libraries or various plugins which live in private directories and have
not been designed to be found or loaded globally.

Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and
hard-coded -install_name flags with a conditional <SONAME_FLAG> which is
expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG
definition as long as soname supports is enabled for the target in
question.  Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in
rules in case third party projects still use it.  Such projects would
not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be
expanded.  Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well.  Since
-install_name is soname on OS X, this should not be a problem if this
variable is expanded only if soname is enabled.

The Ninja generator performs rule variable substitution only once
globally per rule to put its own placeholders.  Final substitution is
performed by ninja at build time.  Therefore we cannot conditionally
replace the soname placeholders on a per-target basis.  Rather than
omitting $SONAME from rules.ninja, simply do not write its contents for
targets which have NO_SONAME.  Since 3 variables are affected by
NO_SONAME ($SONAME, $SONAME_FLAG, $INSTALLNAME_DIR), set them only if
soname is enabled.

Xcode 4.3 installs into "/Applications" by default, from the Mac App Store.

Also, the paths to the available SDKs changed: they are now within the

PackageMaker is installed as a separate program, and may be installed
anywhere. It is not installed with Xcode 4.3 by default anymore.
Download the "Auxiliary Tools for Xcode" to get PackageMaker.
Put PackageMaker inside the Xcode.app bundle, in its nested Applications
folder, or put it alongside Xcode in "/Applications" and CMake will find
it.

Update references to "find" paths: add new possible locations for finding
Xcode.app and PackageMaker.app. Prefer the most recent version's locations
first, but keep the old locations as fallback search paths, too.

Brad King 5d9934312d Do not link private dependent shared libraries on OS X > 10.4
The default OS X 10.4 linker incorrectly searches for dependencies of
linked shared libraries only under the -isysroot location.  It fails to
find dependencies of linked shared libraries in cases such as the
ExportImport test.  It produces errors like:

 /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning can't open dynamic library:
 libtestLib3Imp.dylib
 referenced from: /.../ExportImport/Root/lib/libtestLib3lib.1.2.dylib
 (checking for undefined symbols may be affected) (No such file or directory, errno = 2)
 /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: Undefined symbols: _testLib3Imp
 referenced from libtestLib3lib expected to be defined in
 libtestLib3Imp.dylib

or with CMAKE_SKIP_RPATH off to enable install_name in the Export side:

 /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning can't open dynamic library:
 /Developer/SDKs/MacOSX10.4u.sdk/.../ExportImport/Export/impl/libtestLib3Imp.dylib
 referenced from: /.../ExportImport/Export/libtestLib3lib.1.2.dylib
 (checking for undefined symbols may be affected) (No such file or directory, errno = 2)
 /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: Undefined symbols:_testLib3Imp
 referenced from libtestLib3lib expected to be defined in
 /.../ExportImport/Export/impl/libtestLib3Imp.dylib

Note how "/Developer/SDKs/MacOSX10.4u.sdk" is prepended to the dependent
library path.

Commit 2cff26fa (Support linking to shared libs with dependent libs,
2008-01-31) and commit 82fcaebe (Pass dependent library search path to
linker on some platforms, 2008-02-01) worked around the problem by
defining platform variable CMAKE_LINK_DEPENDENT_LIBRARY_FILES.  It tells
CMake to link to dependent libraries explicitly by their path thus
telling the linker where to find them.

Unfortunately the workaround had the side effect of linking dependent
libraries and defeats most benefits of LINK_INTERFACE_LIBRARIES.
Fortunately OS X 10.5 and above do not need to find transitive
dependencies at all so we can avoid the workaround on Modern OS X.

Brad King 5720e1f634 HP: Drive shared library linking with compiler front end
Previously we linked C, Fortran, and ASM shared libraries compiled with
the HP compiler using a direct invocation of the linker (ld).  This
behavior was left historically from support for an ancient HP C compiler
that did not know how to create shared libraries.  Fortran shared
libraries need to be linked with the compiler to get the language
runtime library dependencies as is already done for C++.

Update the HP-UX-HP* platform information to use the compiler front end
when linking shared libraries.  This works on modern HP tools and
produces correct behavior.  If there is a need to support older tools
again we can add a special case for them.
