[...] For my FreeEOS project I developed FindBLAS.cmake and FindLapack.cmake and a helper file called CheckFortranFunctionExists.cmake to deal with the issue of finding BLAS and LAPACK on my Linux platform. However, my solution didn't deal with other platforms very well because I didn't have the required platform-dependent BLAS and LAPACK expertise. Fortunately, though, Alin Elena was much more in the know about these issues so he took over my efforts and vastly improved them. I understand the result works well on the Mac now since he is particularly interested in that platform. To see his latest version, look for the above files in http://www.cmake.org/cgi-bin/viewcvs.cgi/Modules/?root=CMake. I am completely tied up with something else for the next month or so. Therefore, Jerry, if you are anxious for a quick solution you will have to learn how to use those files for yourself. The basic procedure would be the following: (1) Copy the above files to cmake/modules so that PLplot can access them since we use CMake 2.4.x at the moment rather than the cvs version of CMake. (2) Change ada.cmake in cmake/modules to extract library locations from those files into CMake variables LAPACK_LINKER_FLAGS and LAPACK_LIBRARIES. Follow the last few lines of free_eos.cmake (which can be found at http://freeeos.svn.sourceforge.net/viewvc/freeeos/trunk/cmake/modules/free_eos.cmake?view=log). These first two steps should be completely straightforward, and the two message lines you copy from free_eos.cmake will tell you the resulting values of LAPACK_LINKER_FLAGS and LAPACK_LIBRARIES, i.e., will tell you if CMake found everything properly on your Mac OS X platform If there is any problem with that, then you may need to modify the three files appropriately, but I suspect everything will be fine. (3) Change our Ada library link code (and possible examples as well?) to use LAPACK_LINKER_FLAGS and LAPACK_LIBRARIES appropriately. This step will require a good overview of our build system (so you know where our Ada library and examples are built and with what commands) and will probably require some experimentation to get right. Jerry, good luck with this! Although I am pretty busy at the moment, I am always available to answer a quick question if you run into any roadblocks with the above.
