Hi there,

After experimenting with other functions included in <math.h>, I found
that none of the function in <math.h> can be linked into my program.

I have the libm.a libc.a libpc.a libm_p.a libc_p.a libc_p.a and more
files in my lib directory. I don't have a FPU so I used
set GO32 = emu d:/djgpp/emu387/emu387 in my autoexec.bat file.

The following program will not compile (it compiles in UNIX using gcc -lm ..)
"math.c"
#include <stdio.h>
#include <math.h>
extern double sqrt( double );
 
void main() {
 
(void) printf("%f", sqrt(123.456));
return;
}

When compile with 
gcc -Wall -ansi -lm -lc math.c 

I got the following error messages:

In file included from d:/djgpp/include/varargs.h:7, from d:/djgpp/include/stdio.h:239, from math.c:1:
d:/djgpp/include/stdarg.h:38: warning: built-in function `__builtin_saveregs' redeclared
math.o: Undefined symbol _sqrt referenced from text segment

Does anyone have this problem? Do I have to recompile my libm.a file?
Where can I get a make.exe that will work on the makefile included?

Thanks in advance.
