Hello there!,
I saw people looking for a way to save the error output messages when compiling
I'm currently using this trivial program (Borland C synatx &libs)
#include <dos.h>
#include <stdio.h>
#include <io.h>
#include <stdlib.h>
#if !__COMPACT__
#error Must use compact memory model
#endif
int main(void) {
char far *cmd, *t;
// Parse command line
cmd=MK_FP(_psp,0x81);
while ((*cmd==' ') || (*cmd=='\t')) cmd++ ; // skip leading blanks
for (t=cmd; *t && *t!='\r'; t++) ; // look for terminating return
*t = '\0'; // convert to null
dup2(fileno(stdout),fileno(stderr));
return system(cmd);
}
You use it simply prepending it to the real command and you get stderr and
stdout on the sam redirection.
something like:
errout gcc -c whatever whith options >foo.err
will send error messages and normal output to foo.err
beware that not always the two files are merged right, so if you send to file
the output of a makefile it can happen that the errors come before the line
that caused them I haven't found a clen way to overcome this, but I don't think is a real
problem.
have fun!
