MPICH2 v1.0.6 build without errors, however, there is no shared library: /usr/lib/libmpich.so.0. Building MPICH2-1.2.7_p1 with the same settings results in shared libs in the usually place (/usr/libs64/). Reproducible: Always Actual Results: no file /usr/lib/libmpich.so.0 Expected Results: presence /usr/lib/libmpich.so.0 file

Now fixed in portage...
Sorry, I could've sworn that was a different bug... I can't reproduce this; when I build with (almost) all the USE flags enabled: [ebuild R ] sys-cluster/mpich2-1.0.6 USE="crypt cxx doc fortran mpe mpe-sdk pvfs2 romio threads -debug -fast" 0 kB You should always get the normal shared (and static) lib (the C interface), and adding the cxx and fortran USE flags should give you the C++ and Fortran libs, respectively (the mpe* USE flags will give you additional libs, but that's not the point). I get the following from the above build: $ ls /usr/lib64/libmpich* /usr/lib64/libmpich.a /usr/lib64/libmpichcxx.so /usr/lib64/libmpich.so /usr/lib64/libmpichcxx.so.1 /usr/lib64/libmpich.so.1 /usr/lib64/libmpichcxx.so.1.1 /usr/lib64/libmpich.so.1.1 /usr/lib64/libmpichf90.a /usr/lib64/libmpichcxx.a $ ls /usr/lib64/libfmpich* /usr/lib64/libfmpich.a /usr/lib64/libfmpich.so.1 /usr/lib64/libfmpich.so /usr/lib64/libfmpich.so.1.1 This ebuild has a new .so version because the MPI-PVFS2 interface was updated, and it's not backward compatible. I also committed a fix to another bug, so you can try the updated ebuild and see how that works for you (although it wasn't really a related problem). Please try with and without the cxx/fortran USE flags, and do a qlist of the package after the build and post the libs it creates; if you build with USE="-doc -mpe -mpe-sdk" the package will be a lot smaller...
In a log emerge log file (mpich2-1.0.6) I found something interesting: -------------------------------------- make lib/libmpich.so make[1]: Entering directory `/var/tmp/portage/sys-cluster/mpich2-1.0.6/work/build' (cd lib && /var/tmp/portage/sys-cluster/mpich2-1.0.6/work/build/src/util/createshlib --mode=link -version-info "1:1" -o libmpich.la -rpath /usr/lib64 -L/usr/lib64 -laio ) /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -laio collect2: ld returned 1 exit status ------------------------------------------ I haven't emerged libaio. Emerging libaio resolve my problem. Now I have /usr/lib64/libmpich.so.1.1 and it works (tested with my MPI program). Conclusion: - mpich2-1.0.6 requre libaio dependences (previous version doesn't) - I thing, something is wrong with the ebuild, I haven't obtain any warning or error in emerge summary about this situation tested with the following settings: sys-cluster/mpich2-1.0.6 USE="crypt cxx doc fortran mpe -debug -fast -mpe-sdk pvfs2 -romio -threads"
The shared libs are a little touchy, and there doesn't seem to be a way to get the mpich2 configure stuff to ignore pvfs2 if it's actually installed when you try to build mpich2 without it, as well as other stuff. So it seemed cleanest right now to make libaio a hard dep and remove the romio USE flag, at least until I can get a better configure patch. There's an updated ebuild now if you want to test it...
