Brad King e498527f1d Pass Mac linker flag through all compilers with -Wl,
The Mac linker defines flag -headerpad_max_install_names but not all
front-ends recognize the flag and pass it through (many did in the past,
such as the Apple port of GCC).  Use the -Wl, option prefix to tell
front-ends to pass it through without trying to interpret it.

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
"-Wl,-v" to pass "-v" to the underlying gcc compiler to get verbose link
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.

The expectation of users of the MSVC60, MSVC70, MSVC71, MSVC80, MSVC90

build trees using Makefile generators. It also fixes the one mismatch
in that expectation to be found in the Visual Studio generator world:
previously, the VS 7.1 generator would set *both* MSVC70 and MSVC71;
now, it only sets MSVC71.

When the value of CMAKE_OSX_DEPLOYMENT_TARGET is the empty string, the -mmacosx-version-min flag should not show up on the compiler command line. The logic for selecting default value of CMAKE_OSX_SYSROOT is orthogonal to and independent of the value of the deployment target. The default value for CMAKE_OSX_SYSROOT is the SDK that corresponds to the current version of Mac OSX on which cmake is running. 2010-01-29 11:56:35 -05:00
Brad King 3684f62340 Do not export all symbols from DLLs on Cygwin
In commit "use export all symbols on cygwin" (2003-01-21) we started

cygwin exports all symbols automatically if no symbols are explicitly
exported.  When symbols are explicitly exported we want to honor that
narrow interface.  Therefore this flag should not be passed.

Brad King e46e8fb937 Do not find cyg*.dll on Cygwin
While Cygwin supports linking directly to .dll files, the behavior is
now discouraged.  All Cygwin packages now provide import libraries of
the form lib*.dll.a and CMake has built the import libraries for years.

We believe it is now safe to stop explicitly searching for .dll files
because their import libraries will always be available when the
corresponding header files are available.  Users can always set
find_library cache entries to point at a .dll file by hand if they
really must use one.

Commit "Find locally installed software first" made /usr/local the first
prefix searched to be consistent with the Filesystem Hierarchy Standard:

  http://www.pathname.com/fhs/

The standard also implies that the root prefix "/" should not have any
package or development files.  The "/bin" and "/lib" directories should
have only minimal contents to boot the system.  No "/include" ever
exists.  This commit re-orders the search path prefix list from

  /usr/local
  /
  /usr

to

  /usr/local
  /usr
  /

to prefer package and development files over low-level system files.
See issue #10136.

On Cygwin /usr/lib == /lib and /usr/bin == /bin.  This change also makes
search results report locations as "/usr/..." instead of "/lib/...".

Brad King 9ef3f8e820 Restore -rdynamic in Linux build rules
The commit "Drop -rdynamic from Linux build rules" removed default use
of the flag on Linux.  It was expected to be compatible because any
project using plugins should set ENABLE_EXPORTS on its executables to
export their symbols for use by the plugins in a cross-platform way.
However, it is possible to build without ENABLE_EXPORTS and load plugins
that do not link to any symbols from the executable explicitly.  These
plugins may need to see RTTI and other executable symbols needed by the
language implementation.  Executables using such plugins were broken by
the change.

If we want to remove the -rdynamic flag in the future we should do so in
a compatible way.  At that time we should also remove equivalent flags
on other platforms (like -bexpall on AIX).  We will either need a policy
or an explicit API to disable symbol exports on executables.

The primary purpose of the above-mentioned commit was to avoid passing
the -rdynamic flag to compilers on Linux that do not support it.  In
this commit we restore the flag but only on GNU and Intel compilers
which are known to support it.

See issue #9985.

The problem was that we were setting the initial SDK value based on our own internal default value for deplyment target rather than the user's environment variable choice. The solution is to base the default value for the SDK on the deployment target variable after initially caching the deployment target...

We consolidate duplicate code from Platform/Linux-Intel-<lang>.cmake
files into a macro defined in Platform/Linux-Intel.cmake.

Brad King 77ded39645 Fix GNU C and Fortran flags on SunOS
The commit "Split GNU compiler information files" intended to move GNU
flags from the platform-wide Platform/SunOS.cmake module into

  Platform/SunOS-GNU-<lang>.cmake

using a helper module Platform/SunOS-GNU.cmake to consolidate flags.
However, it accidentally put Fortran flags in the C language module and
left out the Fortran module altogether.  This fixes those mistakes.

Brad King 3e37ca8ecc Move GNU flags from SunOS.cmake to SunOS-GNU.cmake
The GNU-specific link-type flags do not belong in the platform-wide
file.

Brad King 4d72006bd6 Reduce duplication in Platform/<os>.cmake files
Several platform-wide linker flag variables are defined in
Modules/Platform/<os>.cmake files for C and then copied by the
Modules/CMake<lang>Information.cmake file for each language.
We now use this approach for the variables

  CMAKE_EXE_EXPORTS_${lang}_FLAG
  CMAKE_SHARED_LIBRARY_SONAME_${lang}_FLAG
  CMAKE_SHARED_LIBRARY_CREATE_${lang}_FLAGS

to avoid duplication for multiple languages in each platform file.

Brad King 58d6057a52 Fix OS X dylib and module GNU flags
The commit "Split GNU compiler information files" broke the settings of

  CMAKE_SHARED_LIBRARY_CREATE_${lang}_FLAGS
  CMAKE_SHARED_MODULE_CREATE_${lang}_FLAGS

and started using just "-shared" for them.  This worked when tested on newer
Mac machines, but older ones really need "-dynamiclib" and "-bundle" (which are
the documented flags anyway).

Brad King aff3147917 Modernize GNU compiler info on Windows
This moves GNU compiler info on Windows into new-style modules

Brad King 1f06c33f8e Drop -rdynamic from Linux build rules
This is a GNU-specific option that should not be specified for all
compilers on Linux.  It tells the GNU compiler to pass -export-dynamic
to the linker to export symbols from executables for use by plugins.
Since we provide the ENABLE_EXPORTS target property to do the same thing
in a cross-platform way, there is no need to pass -rdynamic always.

Since the option is not useful for GNU tools and breaks other tools on
Linux we simply remove it from CMAKE_SHARED_LIBRARY_LINK_<lang>_FLAGS.
This also allows us to stop setting the variable in other Linux compiler
files just to erase the bad flag.

See issue #9985.

Brad King 4f43c1f276 Singly-quote target names for Watcom linker
The Watcom tools do their own command-line parsing and do not accept
double-quotes.  Instead we single-quote the target output name when
invoking wlink and other Watcom tools.  This fixes support for spaces in
the target output directory path when it is not under the build tree.

Brad King 537906b467 Fix flags for Intel Fortran on Windows
We replace "/MD" with ifort-specific flags as follows:

  /MD  -> /threads /libs:dll
  /MDd -> /threads /libs:dll /dbglibs

We also enable the "/MD" equivalent for all Fortran configurations.
Previously multithreaded dll runtimes were used for release builds and
threaded static runtimes for debug builds.  For mixed Fortran C/C++
projects, this led to link warnings for Debug but not for Release.

See issue #8744.

Brad King ccdd3e943d Fix Intel Fortran SHARED libraries on Linux
The Intel Fortran compiler needs options '-i_dynamic' and '-nofor_main'
to create shared libraries on Linux (for at least one architecture).

Brad King 707d05e936 Fix Intel and MinGW Fortran DLL import libraries
We add Intel and MinGW Fortran linker options to create the import
library portion of a DLL.  This allows other binaries to link to a
Fortran DLL.

We also update the Fortran test to use a .def file to specify exports
since there is no __declspec(dllexport) markup syntax in Fortran.

Brad King 0653286dc6 Split Borland compiler information files
This commit re-writes Borland compiler build rules.  We split the rules
into modern <os>-<id>-<lang> information modules but share a common
macro between languages to avoid duplication.

We also address a bug in the previous rules that would build some target
types against the static Borland runtime and others against the shared
Borland runtime in one build tree.  Now we always use the shared runtime
as is the default in the rules for MS tools.

Brad King f98a4e63fd Avoid (Unix|Windows)Paths.cmake multiple include
Block multiple inclusion because "Modules/CMakeCInformation.cmake"
includes "Platform/${CMAKE_SYSTEM_NAME}" even though the generic
module "CMakeSystemSpecificInformation.cmake" already included it.

The extra inclusion is a work-around to address issue #4772 without
intrusive platform file changes.  Once those changes are made the
work-around and these include blockers can be removed.  See issue #9656.

so that locally-installed software is preferred.

This makes the search consistent with the Filesystem Hierarchy Standard:

Brad King 451d68b7e3 Support GNU/kFreeBSD
GNU/kFreeBSD = FreeBSD kernel + userspace with glibc.  Linux.cmake
doesn't contain anything too OS specific, so we can forward to it.

Here are outputs of /bin/uname on author's machine:
  uname -p ==> i386
  uname -o ==> GNU/kFreeBSD
  uname -s ==> GNU/kFreeBSD
  uname -r ==> 5.4-1-686

Brad King 180c60a86f Fix check for -isysroot on OS X
Previously we checked for this flag by parsing the version number of GCC
out of 'gcc --version', but this is not reliable because the format can
vary greatly.  Now we run 'gcc -v --help' and look for '-isysroot' in
the list of options.

We also now store the result on a per-language basis in the per-compiler
info file "CMake<LANG>Compiler.cmake".  This is necessary to make it
accessible from try-compile projects so that they generate correctly.

Brad King b5e558e291 Fix XL C++ compiler flags on Linux
In Platform/Linux.cmake we add GNU flags as default for the platform
which breaks non-GNU compilers.  Later we should refactor these flag
files to put compiler-specific flags only in files loaded for each
compiler.  Until then this commit fixes the XL C++ compiler flags on
Linux by erasing the GNU flags.  See issue #9469.
