error in make -j 8

[siyu-cu]

Hi,

Thanks for this fantastic work. I follow the instruction and run "make -j 8" or "make -j 2", there's always errors like:
[ 0%] Built target doc
[ 1%] Linking CXX executable ../samos
ld: warning: -L path '/opt/local/lib/libgsl.dylib' is not a directory
ld: library not found for -lgsl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [samos] Error 1
make[1]: *** [src/CMakeFiles/samos.dir/all] Error 2
make: *** [all] Error 2

Could you please help me to figure it out? Thanks very much!

Best,
Siyu

You need to edit the GSL path in the ccmake GUI from /opt/local/lib/libgsl.dylib to /opt/local/lib. I then got another error regarding Qt5 which could be solved by adding the flag such that ccmake -DQt5_DIR=$(brew --prefix qt5)/lib/cmake/Qt5 ../.
