I setup SDL the other night so i cant start learning to make games.

I'm using the tutorials from Lazy Foo. I did lesson 2. And it worked fine. I tried to do it again tonight, and I get ALOT of errors in compiling. This is just SOME of the message I get. The list is larger than can be shown on one terminal screen, even when scrolling up and down. See below.

It looks like your compiler can no longer find the correct X libs or their headers to link everthing up together. Have you updated recently?

These are the kind of errors I get, when try to compile as static. Can you post the command you used to compile? E.g. gcc ?.....?

well, i had to reinstall fedora anyways, and i started messing with the SDL again. Fedora 2 comes with an earlier version of sdl installed. I did the tutorial again, and it worked with the other version. Then I downloaded the new version and did "rpm -U SDL.rpm" and thats when everything quits working. I was wondering if I maybe should have used "rpm -F"?

Anyways, now I'm thinking it might be easier to remove SDL from my computer all together, and install the rpm from scratch with no previous versions. Would this fix the problem? and if so, how do I remove the current version from my pc??


Thanks for your help,
Michael

BTW, I'm compliling with:
g++ -o les2 lesson02.cpp -lSDL

And it worked fine before I updated the SDL.rpm

It's better to use
`sdl-config --cflags --libs` will than be replaced by the output from sdl-config. You can try it in your terminal.
I don't think that this will solve the problem you have, but it's a better way to link against all needed libraries.
