Title: Default sdl code won't compile in Code::Blocks
Post by: Jerrac on August 09, 2009, 09:19:09 pm

I am using the default SDL code provided by the SDL wizard in Codeblocks. It will not compile. Keeps giving me "undefined reference" errors for all the SDL_ functions.

I am using Ubuntu 9.04.

If I compile it manually like this:

Quote

david@tux-alteria:~/workspace/ProjectWhite$ g++ `sdl-config --cflags` -c main.cpp
david@tux-alteria:~/workspace/ProjectWhite$ g++ -o main `sdl-config --libs` main.o

It works fine.

How can I get it to find the functions correctly?

Please post the build log after changing compiler logging to full commandline (change "Settings -> Compiler and debugger... -> Global compiler settings -> [the compiler you use] -> Other settings(rightmost tab)" "Compiler logging" to "Full commandline") .

Did you install the libsdlx.x-dev package after creating the project ?
C::B caches the backticked expressions if they are first used.
If you install the appropriate package after the first use of the expressions, you have to close and reopen C::B (not only the project).

Ah, I did install the sdl dev package afterwards. Restarting Codeblocks worked. Thanks!
