I unzipped into C:\_64\mingw64 - which is not a top level folder as you have
recommended.
I don't know if that's significant, but let's give it a try.
Firstly I remove the C:\_64\mingw64 folder entirely.
Then unzip mingw-w64-bin_x86_64-mingw_20080507.zip into C:\mingw64.
===================================
C:\C>path
PATH=c:\ruby\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\batch
C:\C>type hello.c
#include <stdio.h>
int main(void) {
printf("Hello World\n");
}
C:\C>gcc -o hello.exe hello.c

C:\C>gcc -o hello.exe hello.c
gcc: CreateProcess: No such file or directory
===================================
Yep - we're on Windows Vista (oh, joy !!). But I can fix that error:
===================================
C:\C>set PATH=C:\mingw64\libexec\gcc\x86_64-pc-mingw32\4.4.0;%PATH%
C:\C>gcc -o hello.exe hello.c
hello.c:1:19: error: no include path in which to search for stdio.h
hello.c: In function 'main':
hello.c:4: warning: incompatible implicit declaration of built-in function
'printf'
C:\C>
===================================
I can fix that, too, by setting the CPATH environment variable.
Only problem is there are 2 instances of the standard headers - one instance
in C:\mingw64\mingw\include, and one in
C:\mingw64\x86_64-pc-mingw32\include.
Which instance needs to be found ? I'll try putting the latter first:
===================================
C:\C>set CPATH=C:\mingw64\x86_64-pc-mingw32\include;C:\mingw64\include
C:\C>gcc -o hello.exe hello.c
ld: crt2.o: No such file: No such file or directory
C:\C>
===================================
Need to set the LIBRARY_PATH environment variable, too:
===================================
C:\C>set LIBRARY_PATH=C:\mingw64\x86_64-pc-mingw32\lib
C:\C>gcc -o hello.exe hello.c
ld: cannot find -lgcc
C:\C>set
LIBRARY_PATH=%LIBRARY_PATH%;C:\mingw64\lib\gcc\x86_64-pc-mingw32\4.4.0
C:\C>gcc -o hello.exe hello.c
C:\C>hello
Hello World
C:\C>
===================================
Ok - let's return to try.c:
===================================
C:\C>type try.c
#include <windows.h>
int main(void) {
return 1;
}
C:\C>
===================================
First attempt at building that produces a mass of errors beginning with:
C:\mingw64\x86_64-pc-mingw32\include/intrin.h:13:23: error: emmintrin.h: No
such file or directory
C:\mingw64\x86_64-pc-mingw32\include/intrin.h:14:23: error: xmmintrin.h: No
such file or directory
C:\mingw64\x86_64-pc-mingw32\include/intrin.h:15:22: error: mmintrin.h: No
such file or directory
So let's add the location of those includes to the CPATH environment
variable:
===================================
C:\C>set CPATH=%CPATH%;C:\mingw64\lib\gcc\x86_64-pc-mingw32\4.4.0\include
C:\C>gcc -o try.exe try.c -v

===================================
That seems to have compiled ok. I guess those "ignoring nonexistent
directory" messages might arise from having set the CPATH and LIBRARY_PATH
variables.
We'll just rewrite try.c so that it produces some output:
===================================
C:\C>type try.c
#include <stdio.h>
#include <windows.h>
int main(void) {
printf("At last !!\n");
}
C:\C>gcc -o try.exe try.c
C:\C>try
At last !!
C:\C>
===================================
Beautiful !!
As to what the problem *was* is now a little unclear to me. Perhaps it was
because I originally unzipped into C:\_64\mingw64 instead of a top level
folder. Or perhaps it was something to do with the way I had jumped through
all those hoops.
In the process of the re-installation, I've rewritten the batch file that
sets up the environment - so I can't even go back and take a look at how it
was. (Well, not easily, anyway.)
Is the order in which the various (CPATH and LIBRARY_PATH) locations are
listed going to be of importance ?
One way or another, progress has been made. Thanks for the assistance.
Cheers,
Rob
