Building under MinGW, need step by step guide

[dannyyy]

Hi ! HAPPY HALLOWEEN !!!

I took a shortcut...the only file I really needed was really "wmfconfig.h", so I just renamed the file wmfconfig.h.in which was inside the WMF folder and altered some defines.

Now ImageMagick is compiling perfectly using MinGW and CodeBlocks. Later I will make the files available and write a detailed README.

The only problem I'm having now is about the debug version. On the file "nt-base.h", lines 38 to 40, there is the following:

Code: Select all

#if defined(_DEBUG)
#include <crtdbg.h>
#endif

...but MinGW doesn't has this header. What can I do in this case ?

Oh, and thanks for the help so far !

Try changing the conditional compile statement to:

• #if defined(_DEBUG) && !defined(__MINGW32__)

and let us know if that fixes the problem.

It returned the following errors:

Are those functions VC++ specific ? Or I can find it on the MinGW/GCC headers ?

Change the conditional compile in that area to

• #if defined(_DEBUG) && !defined(__BORLANDC__) && !defined(__MINGW32__)

Sometimes the Windows environment is interpreted in a Visual C context and other times in a Unixy/gcc context. We have not compiled ImageMagick under MinGW lately so you are tripping across a few compatibility issues. Thanks for alerting us to these problems.

We downloaded the latest release of ImageMagick under the MSYS shell and ImageMagick compiled without complaint as follows:

• bunzip -c ImageMagick-6.3.7-2.tar.bz2 | tar xvf -
  cd ImageMagick-6.3.7
  ./configure --disable-shared
  make
  make -k -i install
  convert logo: logo.miff
  identify -verbose logo.miff

We tried compiling with --enable-shared but an internal compiler error exception was thrown.
