Running GCC from within my program

Hello all. I am writing a program to be a sort of gcc/g++ frontend. OF course, to do this, i need to be able to run gcc and/or g++. I also need to be able to capture the output and the return value of it, so i can determine whether i have to show the user the errors, or whether it exited ok.

I don't know of any ways to capture the output, thats why I am asking, but i was thinking this: I could have it > to a file, and then read tha, if all else fails... Tell me what you think, if the other isn't a possibility. Thanks in advance.

Wow. I had no idea it would be that easy. I'm still waiting for my shell account to be activated (cause idon't currently have a working linux) but that looks simple enough to work. Man, you are like the god of the forum...

Thanks!

Everything works except this one part:

Code:

---

(newdecad@grex:~/prog)$ g++ -o epile epile.cpp
epile.cpp: In function `int main(int, char **)':
epile.cpp:85: implicit declaration of function `int pclose(...)'

---

Any ideas?

Code:

---

  79:          fGcc = popen( sCompileString, "r" );
  80:          if( fGcc ) {
  81:                  iGccBufLine = 0;
  82:                  while( fgets( sGccBuf[iGccBufLine], 128, fGcc ) ) {
  83:                          printf( "%s", sGccBuf[iGccBufLine++] );
  84:                  }
  85:                  printf( "%d\n", pclose( fGcc ) );
  86:          }

Do you think it matters that i am using g++ and

Code:

---

#include <cstdio>

---

?

[EDIT/] STill didn't work, trying prototyping


[EDIT] That doesn't seem to work either:

Code:

---

(newdecad@grex:~)$ g++ -o epile epile.cpp
ld: Undefined symbol
  pclose(_iobuf *) 
collect2: ld returned 2 exit status
