Kitware Robot 77543bde41 Convert CMake-language commands to lower case
Ancient CMake versions required upper-case commands.  Later command
names became case-insensitive.  Now the preferred style is lower-case.

Run the following shell code:

cmake --help-command-list |
grep -v "cmake version" |
while read c; do
    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
xargs -0 sed -i -f convert.sed &&

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.

Store in new platform variables

  CMAKE_${lang}_COMPILE_OPTIONS_PIC

In almost all cases, this means duplication of the
CMAKE_SHARED_LIBRARY_${lang}_FLAGS for the _PIC case and using 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
Windows or Cygwin.

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.

2012-05-01 14:09:59 -04:00
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.

David Cole 4693cf8492 Xcode: Detect new default locations of Xcode 4.3 bits and pieces (#12621)
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
Xcode.app bundle.

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.

Thanks to all the contributors who provided and tested out various patches
for fixing this issue. Especially, but by no means limited to:

Brad King bdbbf763d6 Recognize Embarcadero compiler (#12604)
The Borland compiler was re-branded as CodeGear during 2007-2009 and
since 2009 is the Embarcadero compiler.  They offer predefined macros:

  http://docwiki.embarcadero.com/RADStudio/en/Predefined_Macros

and distinguish themselves by __CODEGEARC__ and __CODEGEARC_VERSION__.

Version 6.30 (C++Builder XE) changed the meaning of some flags:

  http://docwiki.embarcadero.com/RADStudio/en/C%2B%2B_Compiler_Option_Changes_for_XE

with flags matching the compiler version.  Leave the flags unchanged
for old Borland versions.  Always set the BORLAND toolchain indicator
for compatibility with existing projects that test it.  Also set the
EMBARCADERO indicator for newer toolchains.

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

 (checking for undefined symbols may be affected) (No such file or directory, errno = 2)

 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.

The GNU 4.x toolchain on MinGW (and therefore MSYS) allows compiler
options to be passed via response files.  Use this to pass include
directory -I options.  This allows the include file search path to be
very long despite shell and mingw32-make command line length limits.

Commit 6a61a8a5 (Honor module .def files with MinGW tools, 2011-02-21)
set CMAKE_LINK_DEF_FILE_FLAG to "-Wl," to enable passing .def files to
the linker on MinGW.  However, older GNU tools in the MSYS shell do not
know how to translate "-Wl,/c/..." to "c:/..." and complain that the
file does not exist.  Instead set the flag to just "" which tells CMake
it can pass the file through the front-end with no special flag.

Brad King 85c0a69a92 Cygwin: Do not define 'WIN32' (#10122)
One of Cygwin's goals is to build projects using the POSIX API with no
Windows awareness.  Many CMake-built projects have been written to test
for UNIX and WIN32 but not CYGWIN.  The preferred behavior under Cygwin
in such projects is to take the UNIX path but not the WIN32 path.

Unfortunately this change is BACKWARDS INCOMPATIBLE for Cygwin-aware
CMake projects!  Some projects that previously built under Cygwin and
are Cygwin-aware when they test for WIN32 may now behave differently.
Eventually these projects will need to be updated, but to help users
build them in the meantime we print a warning about the change in
behavior.  Furthermore, one may set CMAKE_LEGACY_CYGWIN_WIN32 to request
old behavior during the transition.

Normally we avoid backwards incompatible changes, but we make an
exception in this case for a few reasons:

(1) This behavior is preferred by Cygwin's design goals.

(2) A warning provides a clear path forward for everyone who may see
incompatible behavior, and CMAKE_LEGACY_CYGWIN_WIN32 provides a
compatibility option.  The warning and compatibility option both
disappear when the minimum required version of CMake in a project is
sufficiently new, so this issue will simply go away over time as
projects are updated to account for the change.

(3) The fixes required to update projects are fairly insignificant.
Furthermore, the Cygwin distribution has no releases itself so project
versions that predate said fixes tend to be difficult to build anyway.

(4) This change enables many CMake-built projects that did not
previously build under Cygwin to work out-of-the-box.  From bug #10122:

  "I have built over 120 different source packages with (my patched)
   CMake, including most of KDE4, and have found that NOT defining
   WIN32 on Cygwin is much more accurate." -- Yaakov Selkowitz

A fully compatible change would require patches on top of these project
releases for Cygwin even though they otherwise need not be aware of it.

(5) Yaakov has been maintaining a fork of CMake with this change for the
Cygwin Ports distribution.  It works well in practice.  By accepting the
change in upstream CMake we avoid confusion between the versions.

CMake itself builds without WIN32 defined on Cygwin.  Simply disable
CMAKE_LEGACY_CYGWIN_WIN32 explicitly in our own CMakeLists.txt file.

Brad King af2ad90991 Add NAG Fortran compiler information files
On Linux the NAG Fortran compiler uses gcc under the hood to link.  Use

output.  Detect the NAG Fortran directory (using -dryrun) and then honor
object files in the directory referenced in the implicit link line.
Pass real linker options with "-Wl,-Xlinker,".  The -Wl, gets through
the NAG front-end and the -Xlinker gets through the gcc front-end.
