Steps to repro : 1. Clone latest rdma-core from github. 2. Checkout latest master 3. Install dependencies of cmake3, pandoc. 4. Build : [root@CentOS ~]# cd rdma-core/ [root@CentOS rdma-core]# sh build.sh 5. Execute make in build directory: [root@CentOS rdma-core]# cd build [root@CentOS build]# make [root@CentOS build]# ls -lh lib/librdmacm.so* lrwxrwxrwx 1 root root 14 Mar 5 00:22 lib/librdmacm.so -> librdmacm.so.1 lrwxrwxrwx 1 root root 21 Mar 5 00:22 lib/librdmacm.so.1 -> librdmacm.so.1.2.23.0 -rwxr-xr-x 1 root root 404K Mar 5 00:22 lib/librdmacm.so.1.2.23.0 6. Now when we run "make install" it fails : [root@CentOS build]# make install -- Installing: /root/rdma-core/build/share/man/man3/ibv_dereg_mr.3 CMake Error at librdmacm/cmake_install.cmake:72 (file): file INSTALL cannot find "/root/rdma-core/build/lib/librdmacm.so.1.2.23.0". Call Stack (most recent call first): cmake_install.cmake:51 (include) make: *** [install] Error 1 [root@CentOS build]# 7. The librdmacm.so.1.2.23.0 library is cleaned-up or deleted : [root@CentOS build]# ls -lh lib/librdmacm.so* lrwxrwxrwx 1 root root 14 Mar 5 00:22 lib/librdmacm.so -> librdmacm.so.1 lrwxrwxrwx 1 root root 21 Mar 5 00:22 lib/librdmacm.so.1 -> librdmacm.so.1.2.23.0 [root@CentOS build]# git describe v22-118-g0ea43f6 [root@CentOS build]# uname -r 5.0.0-rc8 [root@CentOS build]# cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core) -- Cheers Manu K S
