Gcc compiler not finding header files

I dont know if this is the right place to post this but...

Basicaly, i cant compile a simple program like:

Code:

---

#include <stdio.h>

int main() {
        printf("Hello world");
}

---

using the Mingws gcc c compiler, it just says that:
main.c:1: No include path in which to find stdio.h

i even tried to reinstall mingw with only the gcc compiler, but same error.

i can use a c++ compiler to compile it, but i really need the c compiler atm :\
any sugestions?

You likely have an bad MinGW GCC installation.
What folder/path is the MinGW installation in?
Does the file "stdio.h" exist under that path in a sub-folder?

NOTE: If you have multiple MinGW GCC installed; you MUST not have one installed in X:\mingw for any drive letter in place of X.

My path is D:\utils\mingw32
Its unlikely that i have a bad install of mingw, as i tried reinstaling it 2 times already ( and i also tried on the d:\mingw path)
and yes, stdio.h exists in the mingw/include folder :\

Open an Command prompt (cmd.exe)
Type in the following command; what version do you have?

Code:

---

gcc -v

---

Mine is

Code:

---

gcc version 4.4.1 (TDM-2 mingw32)

---

What does this return?

Code:

---

gcc -print-search-dirs

---

My result is this; the mingw base folder is "c:\greenapps\mingw_gcc4_4x_sjlj_tdm"

Code:

---

install: c:\greenapps\mingw_gcc4_4x_sjlj_tdm\bin\../lib/gcc/mingw32/4.4.1/
programs: =c:/greenapps/mingw_gcc4_4x_sjlj_tdm/bin/../libexec/gcc/mingw32/4.4.1/;c:/greenapps/mingw_gcc4_4x_sjlj_tdm/bin/../libexec/gcc/;/usr/libexec/gcc/mingw32/4.4.1/;/usr/libexec/gcc/mingw32/;/usr/lib/gcc/mingw32/4.4.1/;/usr/lib/gcc/mingw32/;c:/greenapps/mingw_gcc4_4x_sjlj_tdm/bin/../lib/gcc/mingw32/4.4.1/../../../../mingw32/bin/mingw32/4.4.1/;c:/greenapps/mingw_gcc4_4x_sjlj_tdm/bin/../lib/gcc/mingw32/4.4.1/../../../../mingw32/bin/

Note: The "install:" part is the important part for solving this problem.

Delete or rename the folder MinGW on the D drive or delete all other MinGW installations.

Try adding the include search path to directory. You could do this by

Code:

---

gcc -B <directory>

---

This will be included to the list of search paths which the compiler will look for.

Gee... did anyone happen to notice all those "wrong way" slashes in there?

Unless MinGw does something internally to fix them, that's not going to work on any windows install...

(Since I know this will come up... Yes, Win Vista and 7 will correct slashes for the UI elements of it's own browsers, but no version will fix broken environment variables)

Except of course, every Windows version (including MS-DOS) will correct forwards to backwards when passed to any file opening functions. Until they get there, it's just aesthetics. The only time it matters is if you call the Nt* file functions yourself, and no sane person not writing a driver does that.
