Enet and gcc compiling
 

Sorry I'm lazy. I installed enet 1.3.13 and was trying to compile the host.c file but run into errors:

[bkeane@localhost enet-1.3.13]$ gcc -o host host.c `pkg-config --libs libenet`
Package libenet was not found in the pkg-config search path.
Perhaps you should add the directory containing `libenet.pc'
to the PKG_CONFIG_PATH environment variable

Does anyone know the gcc command to manually link enet and what files I need?

Try this:
Edit: You should find out if you actually installed libenet from source, or installed it from binary package, or didn't install at all.

If you did
... then you get /usr/local/lib/pkgconfig/libenet.pc

Either copy libenet.pc to /usr/lib/pkgconfig/

Or do ..

if you have no libenet no gcc command can help you. Probably you need to install enet or enet related development package.

Yeah, I keep forgetting that distributors split packages into 'base' and 'devel' parts (sometime more), eg 'libenet7' and 'libenet-dev'

May I ask why you are trying to compile that file individually? It is part of the source code of the library.

I'm compiling the host.c program to verify the install. Is there a better way?

look: I'm a bit confused, at this moment I have no idea what do you want to achieve.
First: what OS is it? What did you install exactly, and how (you told you installed enet 1.3.13)?
What is in your enet-1.3.13 directory? Why do you think host.c is a program? or What do you mean by that?

As others have said, it is really unclear what you are trying to accomplish.

Please try to restate your question and include:

* Your distro and version
* What, exactly you are trying to accomplish - you ultimate goal, not the goal of the gcc command
