Re: EGCS Mingw32 1.0.2 - compilation problem - undefined referenceto a function

Hi!

try:

bash$ gcc w.c -o w.exe -lgdi32 -luser32

The error messages you are attaching to your mail, is error messages from
the linker (not the compiler). BTW there are some errors in the code as
well. when you type #include<windows.h> in the top of your code, this is
just a message to preprosessor to include declarations of the library file.
After compiling, you need to link the library code. This is done with
-lgdi32 and -luser32.
You can also do this in two steps:

bash$ gcc -c w.c

This will just compile your source, and make the object file w.o

bash$ gcc -o w.exe w.o -lgdi32 -luser32 

This will link the files together to make an executable file.

Regs,
Øystein Johansen

BTW: I think you need to edit yuor code a bit aswell
     -- and, you do not need ; after }
