60 | (description |
61 | "pkg-config is a helper tool used when compiling applications and | |
62 | libraries. It helps you insert the correct compiler options on the | |
63 | command line so an application can use gcc -o test test.c `pkg-config | |
64 | --libs --cflags glib-2.0` for instance, rather than hard-coding values | |
35b9e423 | 65 | on where to find glib (or other libraries). It is language-agnostic, so |
c44899a2 LC |
66 | it can be used for defining the location of documentation tools, for |
