Hello Johannes, It turned out, the solution was REALLY simple: First I used "locate" to search for libbz2.so.1: *[laptop@worklaptop build]$ locate libbz2.so.1/home/laptop/.hashdist/bld/bzip2/yhn7t7sdxdfd/lib/libbz2.so.1.0/home/laptop/.hashdist/bld/bzip2/yhn7t7sdxdfd/lib/libbz2.so.1.0.6/home/laptop/.hashdist/bld/profile/vyafxmz2waou/lib/libbz2.so.1.0/home/laptop/.hashdist/bld/profile/vyafxmz2waou/lib/libbz2.so.1.0.6/lib/libbz2.so.1/lib/libbz2.so.1.0.4/lib64/libbz2.so.1/lib64/libbz2.so.1.0.4* Then I tried to build with LD_LIBRARY_PATH: *[laptop@worklaptop build]$ LD_LIBRARY_PATH="/home/laptop/.hashdist/bld/bzip2/yhn7t7sdxdfd/lib" make[100%] Building CXX object CMakeFiles/demo_poisson.dir/main.cpp.oLinking CXX executable demo_poisson[100%] Built target demo_poisson* No errors this time! I then tried to run the poisson-demo: *[laptop@worklaptop build]$ ./demo_poisson ./demo_poisson: error while loading shared libraries: libbz2.so.1.0: cannot open shared object file: No such file or directory* Once again, I realized I should use LD_LIBRARY_PATH: *[laptop@worklaptop build]$ LD_LIBRARY_PATH="/home/laptop/.hashdist/bld/bzip2/yhn7t7sdxdfd/lib" ./demo_poisson Solving linear variational problem.* AND IT WORKS!!! You've been a huge help. I write the solution to my problem here so other people could/would maybe find the solution from later, if anyone experiences the same issues... I'm grateful for the help and suggestions - I think there's a pretty remarkable speedup from using CPP in comparison with Python (I mean for executing the code, not for writing it)... Thanks all - everything is fine, I think! Now I'll try to learn more from this...
