There doesn't seem to be a documented way to make install rdma-core, at least in the README file. However trying the obvious $ bash build.sh $ cd build $ sudo make install seems to work, almost. After a few 100 lines of promising output I get CMake Error at librdmacm/cmake_install.cmake:76 (file): file INSTALL cannot find "/home/rpearson/src/rdma-core-git/build/lib/librdmacm.so.1.3.31.0": No such file or directory. Looking I see # ls -l build/lib .... -rwxrwxr-x 1 rpearson rpearson 263384 Aug 10 12:31 libqedr-rdmav25.so lrwxrwxrwx 1 rpearson rpearson 14 Aug 10 12:31 librdmacm.so -> librdmacm.so.1 lrwxrwxrwx 1 rpearson rpearson 21 Aug 10 12:31 librdmacm.so.1 -> librdmacm.so.1.3.31.0 -rwxrwxr-x 1 rpearson rpearson 138536 Aug 10 12:31 librspreload.so -rwxrwxr-x 1 rpearson rpearson 112488 Aug 10 12:32 librxe-rdmav25.so .... with no librdmacm.so.1.3.31.0 as advertised. On the other hand if you stop after bash build.sh and before make install you get: -rwxrwxr-x 1 rpearson rpearson 263384 Aug 10 12:31 libqedr-rdmav25.so lrwxrwxrwx 1 rpearson rpearson 14 Aug 10 12:31 librdmacm.so -> librdmacm.so.1 lrwxrwxrwx 1 rpearson rpearson 21 Aug 10 12:31 librdmacm.so.1 -> librdmacm.so.1.3.31.0 -rwxrwxr-x 1 rpearson rpearson 608632 Aug 10 12:31 librdmacm.so.1.3.31.0 -rwxrwxr-x 1 rpearson rpearson 138536 Aug 10 12:31 librspreload.so So the make install seems to be deleting the .so file. Nothing like this is happening to the other libraries. Any help would be appreciated. I would like to be able to install this version of rdma-core on the system. Bob Pearson
