It should work without setting any environment variable. You can even dispense with PATH: C:\tmp>PATH '' C:\tmp>PATH PATH='' C:\tmp>type hello.c #include <stdio.h> void hello() { printf("hello, world!\n"); } int main() { hello(); return 0; } C:\tmp>C:\MinGW-20060119\bin\gcc hello.c C:\tmp>a hello, world!

It depends on the command being used for compiling. For example, without setting any path or environment variable, one can build some projects using a command such as the following (the stuff below is all in one line): x:\hacking\mingw\bin\mingw32-make.exe -f the_make_file THE_DEFIN=its_val CC="x:/hacking/MinGW/bin/gcc -Ix:/hacking/MinGW/include -Lx:/hacking/MinGW/lib" Because of this message that you are seeing > "randint.c:1:19: no include path in which to search for > stdio.h". I suspect you need to start by specifying the right include path via. -I<path> (then you might start seeing linking errors about not finding libraries -- try resolving that with -L<path> and/or -l<value>). --Suresh ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

The issue is probably that your new computer has Vista installed. Search the archives for discussion of the _access() function on Vista. The solution is to download patched versions of the gcc.exe, g++.exe drivers that work as expected on Vista.

I hadn't thought about it as a problem before, but yes, this is a Vista machine. I found <http://www.nabble.com/environment-hosed-during-upgrade-t3305745.html>; where should I put the xgcc-3.4.5.exe I've downloaded, and should I rename it to something else? Is this in fact the patched gcc you were referring to? --Joel ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

Is this in fact the patched gcc you were referring to? Yes. Here is a more convenient set of patched binaries, provided by Brian Dessent, whom I quote: ---------------------------------- If it helps anyone else, I took the three patched drivers that Danny posted (gcc, g++, collect2) and copied them to their various aliases (e.g. c++, mingw-g++, etc) and put them in the appropriate directory structure, and made it a tarball: http://dessent.net/tmp/gcc-vista-3.4.5-20060117-1.tar.gz $ tar ztvf gcc-vista-3.4.5-20060117-1.tar.gz -rwxr-xr-x brian/None 86016 2007-05-18 18:41 bin/c++.exe -rwxr-xr-x brian/None 86016 2007-05-18 18:41 bin/g++.exe -rwxr-xr-x brian/None 83456 2007-05-18 18:40 bin/gcc.exe -rwxr-xr-x brian/None 86016 2007-05-18 18:41 bin/mingw32-c++.exe -rwxr-xr-x brian/None 86016 2007-05-18 18:41 bin/mingw32-g++.exe -rwxr-xr-x brian/None 83456 2007-05-18 18:40 bin/mingw32-gcc-3.4.5 -rwxr-xr-x brian/None 83456 2007-05-18 18:40 bin/mingw32-gcc.exe -rwx------ brian/None 85504 2007-05-18 18:41 libexec/gcc/mingw32/3.4.5/collect2.exe If you unpack this in your MinGW root folder (e.g. /mingw) just like all the other gcc-foo tarballs it should install the files in all the right places. I tested this on a Vista copy running VMware and it worked fine for compiling and linking C and C++. ---------------------------------- --Joel ------------------------------------------------------------------------ - This SF.net email is sponsored by: Microsoft Defy all challenges.
