We've run into another issue with the way FindHDF5 works.On Cray systems, h5fc -show gives:ifort -fPIC -I/opt/cray/hdf5/1.8.5.0/hdf5-intel/include -L/opt/cray/hdf5/1.8.5.0/hdf5-intel/lib /opt/cray/hdf5/1.8.5.0/hdf5-intel/lib/libhdf5hl_fortran.a /opt/cray/hdf5/1.8.5.0/hdf5-intel/lib/libhdf5_hl.a /opt/cray/hdf5/1.8.5.0/hdf5-intel/lib/libhdf5_fortran.a /opt/cray/hdf5/1.8.5.0/hdf5-intel/lib/libhdf5.a -lz -lm -Wl,-rpath -Wl,/opt/cray/hdf5/1.8.5.0/hdf5-intel/lib -L/usr/lib64The FindHDF5 complains it can't find the libraries because it looks for the -l* portions and doesn't find the lines giving the .a files.I will try to think of a general way to make this work, but I'm not very well versed in cmake. So if anybody has any suggestions or knows how to fix it, we'd sure appreciate it!
This will only work for a Unix link line, but most of the compile line reading stuff will only work on a Unix system anyway. But, the regular expression
\(\/[^ \/]*\)*.\.aWill match full paths to static libraries on the link line. I could add something to the _HDF5_parse_compile_line macro to match that expression and append those paths to the candidate set. Do you think that would solve the problem?

Will, Sorry for the delay in responding. We tested the FindHDF5 you attached and it correctly located the Fortran libraries. Thanks for including it in the updated version!

But I think in #3 you're definitely doing something wrong. It took me quite a while to figure out, because the documentation is rather sparse, but whenever there is a hdf5-config.cmake file, you should not read that from a Find*.cmake file. Whenever there is such a file present, what should happen is that CMake finds it and reads it and that's that. Even more precise: whenever a user writes find_package(HDF5) and the hdf5-config.cmake exists, CMake will read that file and will NOT go look for FindHDF5.cmake. The hdf5-config.cmake should then explicitly set all the (cached) variables you normally would have to 'calculate' in the FindHDF5.cmake file. So to be short: the FindHDF5.cmake file should never be required to look for hdf5-config.cmake - CMake should be left to be the one to do that. The HDF5 installer should be the one that installs the hdf5-config.cmake into for example <prefix>/share/HDF5/cmake or some similar path (look for documentation of find_package for possible locations where CMake will look)From previous instructions by the Kitware developers, I was under the impression that I needed to do something likefind_package( HDF5 QUIET NO_MODULE )from the FindHDF5.cmake module. It looks like FindVTK does this. Either way, the HDF5 CMake build does not set the standard *_INCLUDE_DIRS and *_LIBRARIES variables in the config file, so I have to do something. Can a Kitware person shed some light on this?Thanks, WillBut again: I haven't read the actual file you created :P Maybe I'm overlooking some details of this particular package.Greetsz, Jakob Will Dicharry wrote:Hi All,I neglected the FindHDF5 module for a while because I was shifted to another project that was kind of far from CMake work, but there were a few requests for fixes features to the module. I think I have a file that has the important ones. It's attached to this message. Brad, I know I had CVS access, but I don't think I have Git access. If you'd like me to push my commits, I can but I think I'd need you to reauthorize me to do so.The changes to this module are: 1. Tim Gallagher's (cc'd) patch to handle the HDF5 Fortran library.2. hdf5_hl is now an optional component that can be requested like the language bindings. 3. If I can find hdf5-config.cmake from the native HDF5 cmake build, I use it.I'd like it if the people I cc'd (who appear to be interested in at least one of these features) could try it and see if it works for them. I'd also like to know if I did #3 correctly, since there don't really appear to be any modules in the CMake repository that wrap around config files that don't set the variables defined in the Find module.Thanks, Will ------------------------------------------------------------------------ _______________________________________________ Powered by www.kitware.comVisit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.htmlPlease keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQFollow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake_______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
