Chuck Atkins e750761857 OpenBSD: Work-around static/runtime linker inconsistency
Detect the runtime linker's search path and add to the compile time
linker's search path.  This is needed because OpenBSD's static linker
does not search for shared library dependencies in the same places as
the runtime linker.

Brad King 4eba05de42 Suppress GNU flag -fPIC on Windows
Commit "Modernize GNU compiler info on Windows" (2009-12-02) reorganized
GNU flags on Windows but let -fPIC slip through for compilation of
objects in shared libraries.  While this flag is valid on most GNU
compiler platforms we need to suppress it in Windows-GNU.cmake just as
we already do in CYGWIN-GNU.cmake.

David Cole 6ee87b2e5c Fix issue #10155 - default value of CMAKE_OSX_DEPLOYMENT_TARGET should always be the empty string. 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
passing -Wl,--export-all-symbols when linking shared libraries.  Now
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.

Change based on patch from issue #10122.

Brad King 41024b006b Fix CMAKE_DL_LIBS on Cygwin
The variable should contain the name of a library needed to link the
symbol equivalent to dlopen.  On Cygwin no special library is needed,
and certainly not "gdi32".

Change based on patch from issue #10122.

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.

Change based on patch from issue #10122.

Brad King 12dcf9e4fb Search prefix /usr before root prefix /
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/...".
See issue #10122.

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.

David Cole 8d88de4b4a Fix issue with SDK not matching initial deployment target chosen by setting the MACOSX_DEPLOYMENT_TARGET environment variable. 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... Every time I'm in this code I think I leave it cleaner, only to be proven otherwise. Let's give this one a whirl. Bleh. 2009-12-23 12:08:25 -05:00
David Cole a830786c44 Fix issues #9959 and #9898 - do not set CMAKE_OSX_DEPLOYMENT_TARGET if CMAKE_OSX_SYSROOT is set.
Default to "" for CMAKE_OSX_DEPLOYMENT_TARGET if CMAKE_OSX_SYSROOT is set. Also, add new error message to detect the case where there is a deployment target, but no SDK has been set. Fix args to STRING REGEX call so that it works even if _sdk_path variable is empty inside sanity check function.

Brad King af14f1f2c3 Remove GNU-specific flags from Linux.cmake
We remove the shared library compile/link flags "-fPIC" and "-shared"
because they are not provided by all compilers on Linux.  This allows us
to drop code from the Linux-XL-*.cmake files that erases the bad flags.
All other supported compilers already provide their correct flags for
Linux in their own platform information files.

and invoke the macros from

  Compiler/PGI-<lang>.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 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 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 707d05e936 Fix Intel and MinGW Fortran DLL import libraries
We add Intel and MinGW Fortran linker options to create the import

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.

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.
