Re: [perl-win32-gui-users] How can I install Win32-GUI-DIBitmap without MSVC?

Your PPM install is probably good because you can load Win32::GUI::DIBitmap.

I think problem come from how you run demo.pl script.
This script don't work if current directory isn't samples directory.
Because it try to load a bitmap in bmp subdirectory using a relative path.
If you aren't in samples directory, Win32::GUI::DIBitmp new methods return
undef. So, ConvertToBitmap don't work because $dib is undef.

You need Visual C++ for build from source because DIBitmap isn't a pure perl
module. It's build a special perl dll from C source code (like Win32::GUI).

You must build source with FreeImage Static lib Project with MSVC.
Generaly, static lib can be found in FreeImage\Source\FreeImageLib\Release
directory.

You probably use import library for FreeImage.dll.
I don't know if it work using extrenal freeImage.dll.

Look good here ;)

Strange ??
It's look like a auto-extractable exe file.
nmake command it's for build module in current directory.

You must have Visual C++ and have Visual C++ bin directory in your path.
Generaly, you can run a VCVARS32.bat file from Visual C++ bin directory for
setup environement.

If you don't have Visual C++, it's possible to build compatible ActivePerl
extention using MinGW (free).
Look, to my web page for an howto with MinGW and Win32::GUI.
http://perso.club-internet.fr/rocherl/HowTo/howto-mingw.html
I never test to build DIBitmap with MinGW.
