Qt4/C++ - Adding a 'C' program - missing stdarg.h

Hello,

I'm trying to add an existing 'C' file to my Qt4 project, and have a header missing - 'stdarg.h'.

I can find matching file files on my system.

sudo find -name stdarg.h
./usr/include/c++/4.6/tr1/stdarg.h
./usr/lib/gcc/arm-linux-gnueabihf/4.8/include/stdarg.h
./usr/lib/gcc/arm-linux-gnueabihf/4.6/include/stdarg.h

I can put the full path in the 'C' file, but would prefer not to change the 'C' file, if possible.
Would it be reasonable, just to copy the header to my source directory?
This would still need a change to the 'C' source. <stdarg.h> to "stdarg.h".
Would it be possible to add it to the .pro file, as a +=include?

Regards

What platform are you building on? A Linux I assume.
What platform are you building for?

Does this program:

Code:

---

/* test.c */
#include <stdarg.h>
 
int main(int argc, char **argv) { return 0; }

---

compile with:

Code:

---

gcc -v -c test.c

---

or whatever your C compiler is actually called? The verbose output will tell you exactly where it will look for stdarg.h.

Hello,

Thanks for your reply.

It produces a test.o file

Hello,

A solution I've found that seems to work is :-

Add INCLUDEPATH += /usr/lib/gcc/arm-linux-gnueabihf/4.6/include/ to the pro file.
