Compile/Link issues on MSYS2/MinGW-w64 of ImageMagick 7.0.3-4

[Emilyl]

I'm having trouble with compiling and linking ImageMagick under the MSYS2 (http://msys2.github.io/) environment using MinGW-w64 compiler. Here are the steps I've taken:

Code: Select all

git clone https://github.com/ImageMagick/ImageMagick.git
git checkout 7.0.3-4
./configure --prefix=/mingw64/ --disable-deprecated --disable-openmp --without-fontconfig --without-threads --without-perl --enable-shared --enable-static=no --with-modules --without-x --without-freetype && mingw32-make.exe -j8

I'm building for integration in a JNI library where IM is only used for loading images so I want to minimize dependencies, hence disabling stuff.

I get a lot of warnings during compilation:

Code: Select all

./MagickCore/nt-base.h:32:0: warning: "_CRT_SECURE_NO_DEPRECATE" redefined
./MagickCore/nt-base.h:98:0: warning: "MAGICKCORE_HAVE_ERF" redefined
./MagickCore/studio.h:129:0: warning: ignoring #pragma comment  [-Wunknown-pragmas]
 #pragma comment (lib, "ws2_32.lib")

Which indicate a problem, especially the pragma comment lib.

But the actual failure happens later:

Code: Select all

I have to use mingw32-make.exe as make fails with:

Code: Select all

$ make
CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/sh /d/work_java/ImageMagick/config/missing autoconf
sh: gitversion: command not found
' is already registered with AC_CONFIG_FILES.

Note, apparently MSYS2 team is maintaining a patchset for MinGW-w64 compilation:

https://github.com/Alexpux/MINGW-packag ... magemagick

Could parts of this be merged upstream?

We recently compiled ImageMagick 7 under MSYS2/MinGW-w64 without the need for patches. We make another attempt to confirm and report back in a few days.

I think there is more to this than simply compiling it. Part of this is that you might want to run ImageImagick programs from the command line, a bash script, or sometimes as part of a build process. In MSYS2, paths are specified more like they would be in Unix than Windows and there is a Unix-like File System HIerarchy. Arguably, there's actually three hierarchies each with their own individual toolchains.

/mingw32 - lib/ include/ bin/ etc/ source/ share/ and a few other things. Those are for MINGW 32-bit development. Native Win32 .exe and .dlls are an end-goal

/usr /etc /include /lib /dev /proc - The MSYS2 environment and stuff for building this environment and it's components.

There was a bug recently that caused ImageMagick not to locate some image modules. See: https://github.com/Alexpux/MINGW-packages/issues/1885 . The package was building coders in something "mingw32/lib/ImageMagick-7.0.3/modules-Q16HDRI/coders/". There was also abug that had to do with the strings namespace that had to be solved with a patch.
