I had GSL (Gnu Scientific library) installed on my Ubuntu 14.04 and it was working fine. I then upgraded to Ubuntu 16.04 and now if I try to compile C++ code using GSL I obtain the error message
g++ -c FILE.cpp In file included from FILE.cpp:1:0: FILE.h:3:28: fatal error: gsl/gsl_matrix.h: No such file or directory compilation terminated. Makefile:42: recipe for target 'FILE.o' failed make: *** [FILE.o] Error 1
How do I fix this issue?
