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. > > then I tryed to install this module from scratch, how it wrotten in > Readme.txt : > > SP> INSTALLATION > SP> > SP> Download FreeImage source code at http://freeimage.sourceforge.net/ > SP> Build the FreeImage static lib with MSVC project. > SP> Copy the FreeImage.lib and FreeImage.h in the extlib directory. > > Instead I am copied FreeImage\Dist\FreeImage.lib in extlib directory. > Is it the same file??? 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. > > SP> To install this module type the following: > SP> > SP> perl Makefile.PL > ..... > Writing Makefile for Win32::GUI::DIBitmap Look good here ;) > SP> make # nmake > Searching EXE: E:/WINDOWS/EXE/NMAKE.EXE > Inflating: NMAKE.ERR > Inflating: NMAKE.EXE > PKSFX: (W18) Warning!

It's look like a auto-extractable exe file. nmake command it's for build module in current directory. > SP> make install # nmake install > ..... > Der Befehl "cl" ist entweder falsch geschrieben oder # from German: > konnte nicht gefunden werden. # cl not found > > NMAKE : fatal error U1077: 'C:\WINDOWS\system32\cmd.exe' : return code '0x1' > Stop. > > Have I to have a linker programm too? > 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. Laurent.
