MinGW Configure Question (WINGDI32_DELEGATE)

Hi, I know MinGW is not the focus of ImageMagick, but hopefully I have a very simple question to answer. When running ./configure on the latest version of ImageMagick in MinGW on Windows 7, I was curious about the following snippet (from the ./configure script):

Code: Select all

if test "${GDI32_LIBS}x" != 'x'; then
  $as_echo "#define WINGDI32_DELEGATE 1" >>confdefs.h
fi

if test "${GDI32_LIBS}x" != 'x' ; then
  WINGDI32_DELEGATE_TRUE=
  WINGDI32_DELEGATE_FALSE='#'
else
  WINGDI32_DELEGATE_TRUE='#'
  WINGDI32_DELEGATE_FALSE=
fi
When I build on MinGW, I get the following errors (which I think are related to the above snippet in the ./configure script):

Code: Select all

To solve the build error, I applied the following patch:

Code: Select all

-if test "${GDI32_LIBS}-x" != 'x'; then
  -$as_echo "#define WINGDI32_DELEGATE 1" >>confdefs.h
-fi
-
-if test "${GDI32_LIBS}x" != 'x' ; then
-  WINGDI32_DELEGATE_TRUE=
-  WINGDI32_DELEGATE_FALSE='#'
-else
   WINGDI32_DELEGATE_TRUE='#'
   WINGDI32_DELEGATE_FALSE=
-fi
It seems like many conflicts exist between the gdiplus header files (for example: gdipluspixelformats.h) and ImageMagick header files. And when I apply this patch, it seems to solve the build errors. However, I would love to hear somebody's thoughts on this error, and let me know how to avoid all the conflicting declarations between gdiplus and ImageMagick. And hopefully there is a simple explanation and solution. =)

Your build is broken because I recently integrated the code from emfplus.exe into the emf coder. This will be fixed in the next release.
