Linking nheqminer failed Ubuntu 17.04

[brentmsmith]

I compiled with gcc-5 and g++-5 and all seems to compile fine but the make dies at the last stage: make -j 8 [ 27%] Built target cpu_xenoncat [ 27%] Built target cuda_djezo [ 27%] Linking CXX executable nheqminer /usr/bin/ld: /usr/lib/x86_64-linux-gnu/librt.a(shm_open.o): relocation R_X86_64_32 against ``.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: /usr/lib/x86_64-linux-gnu/librt.a(shm_unlink.o): relocation R_X86_64_32 against ``.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: final link failed: Nonrepresentable section on output collect2: error: ld returned 1 exit status CMakeFiles/nheqminer.dir/build.make:502: recipe for target 'nheqminer' failed make[2]: *** [nheqminer] Error 1 CMakeFiles/Makefile2:68: recipe for target 'CMakeFiles/nheqminer.dir/all' failed make[1]: *** [CMakeFiles/nheqminer.dir/all] Error 2 Makefile:127: recipe for target 'all' failed make: *** [all] Error 2 Not sure exactly what this is telling me. Any advice would be appreciated.

I am able to reproduce this failure on Ubuntu Zesty 17.04 even after adding -fPIC to the compiler flags.

cmake .. \
  -DCUDA_NVCC_FLAGS="-ccbin gcc-4.9" \
  -DCMAKE_C{XX,}_FLAGS="-fPIC" \
  -DBUILD_SHARED_LIBS=ON && \
    make -j $(nproc)

I'm working off of HEAD@b9900ff except for the following change to allow the "build" dir to exist inside the working copy:

Probable duplicate of #300

Same issue, but I've realized that there exist

/var/lib/dpkg/info/libboost-log1.62-dev.list

instead of

/var/lib/dpkg/info/libboost-log1.62-dev:amd64.list

I worked around this by: ../cmake find ./ -type f -exec sed -i 's/librt.a/librt.so/g' {} \; make -j $(nproc)
