Compiling source code in Windows

[el_supremo]

I tried to compile the current version 6.6.3-8 on Windows and ran into a few problems.

When building the CORE_magick project, the function InitializeCriticalSectionandSpinCount is undefined. The way to make windows define and link this function is to include this define:

Code: Select all

#define _WIN32_WINNT 0x0501

But this must occur before the include of <windows.h>. I got around this by putting the define in magick_config.h but there's probably a better way to do it.

When building CORE_lcms, the function sqrtf is undefined. In lcms2_internal.h I added a define inside an existing #ifdef:

Code: Select all

// Other replacement functions
#ifdef _MSC_VER
# ifndef snprintf
#       define snprintf  _snprintf
# endif
# ifndef vsnprintf
#       define vsnprintf  _vsnprintf
# endif
//PAH Added this
#define sqrtf(x) (float)sqrt((float)x)
#endif

In IM_MOD_wmf vsnprintf is undefined so I added this at the front of wmf/src/stream.h:

Code: Select all

#ifdef _MSC_VER
# ifndef vsnprintf
#       define vsnprintf  _vsnprintf
# endif
#endif

Thanks for the patches. We'll get them into the next point release of ImageMagick.

Something still amiss. I get the (probably) same error in 6.4.4-1:

I'll try Pete's #define trick in the morning...

I got around this by putting the define in magick_config.h

It worked (in magick-config.h, not magick_config.h). I have no idea why, but thanks, Pete.

Any prognosis for the problem?

Look for this patch in the next point release of ImageMagick.
