The XL toolchain supports shared object files stored in archives. Since CMake lists libraries on link lines by full path it is common for a shared library link line to contain the path to an archive file. When linking a shared library the compiler front-end by default runs CreateExportList to construct the list of symbols to be exported. Unfortunately it passes all files found on the command line to the tool so archive and library files get processed along with the object files. The tool returns a list of all symbols in all objects, archives, and libraries on the command line. This causes the linker to copy every object file out of every archive into the shared library whether they are dependencies of the original object files or not. Work around this problem by running CreateExportList ourselves with just the original object files intended for inclusion in the shared library. Then pass the list it produces on the link line to prevent the compiler front-end from constructing its own. This tells the linker to export only the symbols provided by the original source files of the shared library.
This is CMake, the cross-platform, open-source make system. CMake is distributed under the BSD License, see Copyright.txt. For documentation see the Docs/ directory once you have built CMake or visit http://www.cmake.org. Building CMake ============== Supported Platforms ------------------- MS Windows, Mac OS X, Linux, FreeBSD, Solaris, HP-UX, IRIX, BeOS, QNX Other UNIX-like operating systems may work too out of the box, if not it shouldn't be a major problem to port CMake to this platform. Contact the CMake mailing list in this case: http://www.cmake.org/mailman/listinfo/cmake If you don't have any previous version of CMake already installed -------------------------------------------------------------- * UNIX/Mac OSX/MinGW/MSYS/Cygwin: You need to have a compiler and a make installed. Run the bootstrap script you find the in the source directory of CMake. You can use the --help option to see the supported options. You may want to use the --prefix=<install_prefix> option to specify a custom installation directory for CMake. You can run the bootstrap script from within the CMake source directory or any other build directory of your choice. Once this has finished successfully, run make and make install. So basically it's the same as you may be used to from autotools-based projects: $ ./bootstrap; make; make install * Other Windows: You need to download and install a binary release of CMake in order to build CMake. You can get these releases from http://www.cmake.org/HTML/Download.html . Then proceed with the instructions below. You already have a version of CMake installed --------------------------------------------- You can build CMake as any other project with a CMake-based build system: run the installed CMake on the sources of this CMake with your preferred options and generators. Then build it and install it. For instructions how to do this, see http://www.cmake.org/HTML/RunningCMake.html
