Modestas Vainius 1ed19bcb25 multiarch: Set CMAKE_LIBRARY_ARCHITECTURE_REGEX for Linux|Hurd|kFreeBSD
* Fix linux CMAKE_LIBRARY_ARCHITECTURE_REGEX to support armel-linux-gnueabi.
* Add CMAKE_LIBRARY_ARCHITECTURE_REGEX on kFreeBSD.
* Add CMAKE_LIBRARY_ARCHITECTURE_REGEX on GNU (Hurd).

Also regex is improved to support quadlets.  Even if I have not seen this
in the wild yet, reportedly they are possible.

Brad King b41ad3b399 Teach find_(library|package) about Linux multiarch (#12037)
Implement support for multiarch as specified here:

  http://wiki.debian.org/Multiarch
  https://wiki.ubuntu.com/MultiarchSpec

Detect the <arch> part of <prefix>/lib/<arch> from the implicit library
search path from each compiler to set CMAKE_<lang>_LIBRARY_ARCHITECTURE.
Define CMAKE_LIBRARY_ARCHITECTURE using one of these values (they should
all be the same).  Teach the find_library and find_package commands to
search <prefix>/lib/<arch> whenever they would search <prefix>/lib.

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.

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 e28c16b482 Split GNU compiler information files
This moves GNU compiler flags into new-style modules

  Compiler/GNU-<lang>.cmake
  Platform/<os>-GNU-<lang>.cmake

We use language-independent helper modules

  Compiler/GNU.cmake
  Platform/<os>-GNU.cmake

to define macros consolidating the information.

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.

Bill Hoffman 6a1a1b632d BUG: fix for bug 4772, enable_language should now work on linux with correct flags 2008-10-01 13:24:51 -04:00
Brad King fd37a6ec3d ENH: Better linker search path computation.
- Use linker search path -L.. -lfoo for lib w/out soname
    when platform sets CMAKE_PLATFORM_USES_PATH_WHEN_NO_SONAME
  - Rename cmOrderRuntimeDirectories to cmOrderDirectories
    and generalize it for both soname constraints and link
    library constraints
  - Use cmOrderDirectories to order -L directories based
    on all needed constraints
  - Avoid processing implicit link directories
  - For CMAKE_OLD_LINK_PATHS add constraints from libs
    producing them to produce old ordering

Brad King 82fcaebe28 ENH: Pass dependent library search path to linker on some platforms.
- Move runtime path ordering out of cmComputeLinkInformation
    into its own class cmOrderRuntimeDirectories.
  - Create an instance of cmOrderRuntimeDirectories for runtime
    path ordering and another instance for dependent library
    path ordering.
  - Replace CMAKE_DEPENDENT_SHARED_LIBRARY_MODE with explicit
    CMAKE_LINK_DEPENDENT_LIBRARY_FILES boolean.
  - Create CMAKE_LINK_DEPENDENT_LIBRARY_DIRS boolean.
  - Create variables to specify -rpath-link flags:
      CMAKE_SHARED_LIBRARY_RPATH_LINK_<LANG>_FLAG
      CMAKE_EXECUTABLE_RPATH_LINK_<LANG>_FLAG
  - Enable -rpath-link flag on Linux and QNX.
  - Documentation and error message updates

Brad King eab81489f1 ENH: Added global property FIND_LIBRARY_USE_LIB64_PATHS to allow lib64 paths to be searched optionally. Turn off the feature on debian systems. This addresses debian report 419007. 2007-06-27 12:07:34 -04:00
Brad King 96232d4052 BUG: Detect debian with existence of /etc/debian_version so things work in a chroot install. This is suggested in bug#4805. 2007-05-07 18:17:32 -04:00
