Easiest Way to Check for Librarys before Compiling
 

For instance when compiling an application there are some build requirements. Whats the easiest way to see if I have those installed. I am using Slackware.

Edit: Wow I spelled libraries wrong. I'm an idiot.

Isn't it the role of ./configure?

But say for instance a build needs libglib2.0-dev >= 2.6 but 2.10+ is highly recommended.

Have you got any particular problem compiling something specific or is it a general question?

It's not that I've got any extensive experience with dependencies but I don't remember ever seeing anything like
it. If it says that 2.10+ is required then anything lower will fail. If it says that 2.0 is required, anything higher will
work as well. If the developers of a program decided that using 2.0 would make the program unstable or lacking some functionality, I assume they would completely abandon 2.0 support and clearly state that 2.10 is required.
Having said that, I'm not a developer so ...

Just curious.

.... should send you off here first.
