Dear all, I use an Ubuntu Linux system and have extracted the gsl files into ~/Programme (thus ~/Programme/gsl/* are all the downloaded files) and have installed anything into the basic structures.
My blub.cpp lies in the ~/Programme/testprogramme and I looked into the /usr/local/lib folder and have found the files you have mentioned. If I use now the command g++ -L/usr/local/lib -lgsl -lgslcblas -lm blub.cpp I still get the old error. Might it be possible that I need another package which might be necessary? Best regards, Benedikt ________________________________________ Von: Mark Galassi <m...@galassi.org> Gesendet: Donnerstag, 30.

So there might be the need for a bit more, but you should be able to use the instructions here: https://www.gnu.org/software/gsl/doc/html/usage.html#compiling-and-linking I note that you did a single instruction to compile and link, while the documentation shows separate ones. That means that you should put the link instructions in your single command. You could try: g++ -I ../gsl-2.6 blub.cpp -o blub -L../gsl-2.6/lib -lgsl -lgslcblas -lm Note that I made the guess that your libraries were installed in ../gsl-2.6/lib, but I really don't know if that's where they are. You should use the -L option to point to where files like libgsl.so and libgslcblas.so are located.
