Linker error - Can't use stdlib.h or math.h functions!
« on: March 04, 2013, 05:37:33 pm »
When I try to use stdlib.h functions (regardless of whether I #include <stdlib.h> or not), I get linker errors like these:
Code: [Select]
bullets.o: In function '_freeList':
bullets.c:(.text+0x384): undefined reference to '_free'
bullets.o: In function '_createNode':
bullets.c:(.text+0x39c): undefined reference to '_malloc'
Same for math.h functions. I also have the fxcglib installed. Are these functions not implemented yet?

Thanks in advance!

How did you compiled your program? What's the gcc command line used to compile this?

Both malloc and free are implemented in <stdlib.h>, but try including the raw library in your build folder and using
Code: [Select]
#include "stdlib.h" to see if that fixes the problem. Otherwise, you're not calling the linker properly.

However, I can't change this because the make.bat file calls make.exe in the /bin folder.

Will try!


Edit: tried it, and got the same error.

Try -lc in the command line?

Well, I use the make.bat file, which calls make.exe, so using -lc here doesn't work.

Deleting the -nostdlib flag in /common/prizm_rules and calling make.bat again resulted in these errors:
Code: [Select]
...: In function 'stack_k':
(.text+0x50): undefined reference to '_stack'
..._end_k; end
_main_k; __setup_argv_and_call_main
_atexit_k; _atexit
And it goes on and on.
