2.3 Troubleshooting dependencies

Sometimes, ./configure says it cannot find a library while the library is installed. Really, it may just not find its headers which live in a separate package. Many modern operating system distributions split a library into two packages:

1. A package with binary files, say a libfoo package, which contains the files necessary to run programs which use libfoo.
2. A development package, libfoo-dev or libfoo-devel, which contains the files necessary to compile programs which use libfoo.

If you’re having problems, make sure that you have all of the necessary development packages installed.
