Question

For a C project I’m writing I need to use the GMP library, which I have untarred into my Home directory (using OpenBSD OS with bash). I’m working with others over git, so I can’t change the headers to relative files and at the moment the GCC is giving errors about not being able to find it. I don’t have root privelidges, so I can’t just install it.

How do I get the GCC to look for the GMP library in my home folder instead of the usual place?

Answer 1

When compiling use the argument -I to tell GCC where to look for header files, and -L to tell GCC where to look for libraires.

For example:

$ gcc -I/location/of/library/headers -c foo.c -o foo.o
$ gcc -L/location/of/library/libs foo.o -o foo -llibrary
