Hi! When building MPICH 3.1.4 with ./configure options --enable-checkpointing --with-hydra-ckpointlib=blcr, as specified at: https://wiki.mpich.org/mpich/index.php/Checkpointing I'm get the error: CC src/pmi/simple/lib_libmpi_la-simple_pmiutil.lo CC src/pmi/simple/lib_libmpi_la-simple_pmi.lo GEN lib/libmpi.la /usr/bin/ld: cannot find -lblcr collect2: error: ld returned 1 exit status Makefile:16217: recipe for target 'lib/libmpi.la' failed make[2]: *** [lib/libmpi.la] Error 1 make[2]: Leaving directory '/tmp/tmp.stowinstall.kvTp' Makefile:40727: recipe for target 'install-recursive' failed make[1]: *** [install-recursive] Error 1 Looking at ./configure.ac, on line 5515, I find the string -lblcr. Shoudn't that be -lcr. As far as I know, the BLCR shared library filename is libcr.so, on my Debian system as well as in a BLCR RPM file I found at pkgs.org. The -lblcr string was introduced in configure.ac on GIT revision 51db1a05720c3d1a51eff58084a02b6b6c66e80f http://trac.mpich.org/projects/mpich/changeset/51db1a05720c3d1a51eff58084a02... If I change it to -lcr in configure.ac and run autoconf, I can build successfully, and mpiexec.hydra ends up correctly linked to libcr.so.0. I don't think I have an MPICH TRAC account, so I couldn't submit this as a bug report.
