Hello,
I use DJGPP 2 and try to compile and assmble to object files and =
generate the program:
test1.S:
...
.global _TestFunction
.align 4
_TestFunction: pushl %ebp
/* some stuff */
ret
test2.c
extern int TestFunction(int nr1);
void main()
{
...
TestFunction(4711);
...
}
I compile it:
gcc -c test1.S -o test1.o
gcc -c test2.c -o test2.o
ar rs all.a test1.o test2.o
gcc -o testprogram.exe all.a
but the link gives a undefined referenced TestFunction(int)! Can you =
help me?
