MINGW32

MINGW32

[Uri Yanover]

Hello anybody!
I am a beginning programmer for Windows. I heard of GNU ports for
DOS/Windows. I chose MINGW32 , so I downloaded the binaries, the libraries,
the tools etc. I installed it (unzipped and set up the environment). Then I
compiled and linked a few examples (one from the SDK and one from Petzold)
using the main libraries (user32, gdi32, kernel32, comdlg32 and  comctl32),
like this.

SET DEFAULTLIB=c:\mingw32\lib
SET GUILIBS=-L%DEFAULTLIB% -luser32 -lgdi32 -lkernel32 -lcomdlg32 -lcomctl32
gcc -c hellowin.c
gcc -o hellowin.exe hellowin.o %GUILIBS%

It generally worked, but it shows up a console window. It is reported as
c:\windows\system\conagent.exe in its properties, but I guess it is not so
informative. I also know that each Win32 application has a console attached
to it, but as far as I know the startup code should normally get rid of it.
Unfortunately, I do not have enough experience to clear it all up myself, so
I would like to ask you. Any help would be appreciated.

What version are you running? The latest versions are at:

  http://www.xraylith.wisc.edu/~khan/software/gnu-win32/

No setup required, just run self-extracting executable to install, 
add the binary directory to PATH and go.

>SET DEFAULTLIB=c:\mingw32\lib

Not needed in the new releases (4 in the last 1-1/2 years or so).

>SET GUILIBS=-L%DEFAULTLIB% -luser32 -lgdi32 -lkernel32 -lcomdlg32 -lcomctl32

-luser32 and -lkernel32 are automatically linked in, so no need. `gcc -v'
when linking shows exactly what's being linked in, so that's a good 
diagnostic tool.

>gcc -c hellowin.c
>gcc -o hellowin.exe hellowin.o %GUILIBS%

Add -mwindows, which expands to the following, to avoid the DOS window: 
  -Wl,--subsystem,windows -lgdi32 -lcomdlg32

So, the following are equivalent:
  
  $ gcc -c hellowin.c
  $ gcc -o hellowin.exe hellowin.o -mwindows -lcomctl32

To see what's going on, add the -v option:

  $ gcc -v -o hellowin.exe hellowin.o -mwindows -lcomctl32

Mingw32 questions are probably best posted to the appropriate mailing
lists -

  - Cygwin -- http://sourceware.cygnus.com/lists.html ) -- Mingw and Cygwin
    share the same development tools, so the answers are the same.
  - Mingw32 -- http://www.eGroups.COM/lists/mingw32.html

Thanks for the helpful information!
I was using MINGW32 based on GCC 2.8.1 under Windows 95's DOS box and I
never knew that there was a newer vesion.
Thanks again,

Perhaps that first link should be " http://sourceware.cygnus.com/ml/ " ?
