I am trying to build GCC6.1 with openacc offloading support. I am using the following script. https://github.com/olcf/OLCFHack15/blob/master/GCC5OffloadTest/auto-gcc5-offload-openacc-build-install.sh I have used the same script previously to build gcc5.2 as well. I modified and used it to build gcc 6.1 on my machine with Linux Mint. It built successfully. This was using gcc 4.8 The problem is when I try to build it on another machine. It stops giving the error, /bin/bash /test/Nvidia/OpenACC/OLCFHack15/gcc6/src/gcc/libgcc/../mkinstalldirs /test/Nvidia/OpenACC/OLCFHack15/gcc6/install/lib/gcc/x86_64-pc-linux-gnu/6.1.0/include /usr/bin/install -c -m 644 unwind.h /test/Nvidia/OpenACC/OLCFHack15/gcc6/install/lib/gcc/x86_64-pc-linux-gnu/6.1.0/include make[2]: Leaving directory `/test/Nvidia/OpenACC/OLCFHack15/gcc6/build/gcc6/x86_64-pc-linux-gnu/libgcc' /bin/bash: line 3: cd: x86_64-pc-linux-gnu/libstdc++-v3: No such file or directory make[1]: *** [install-target-libstdc++-v3] Error 1 I thought it maybe was a problem with the gcc version. But the machine had gcc 4.4 and gcc 5.2. I used both of them, but they gave the same error. I then manually copied libstdc++ and then configured and compiled it, and reran the script and then it gets stuck at libsanitizer. I don't know whether the manual process will work for the whole thing, so I am raising this question. I know that another person has also experienced the same issue. Any ideas. Thanks, Vikram
