Use ImageMagick 7 or GraphicMagick

[swdmnd]

Is it possible to build this using ImageMagick 7 or GraphicMagick?

To build against ImageMagick 7, you can remove this override: https://github.com/libvips/build-win64-mxe/blob/50edec409a6bfaf4f34300966dfdb2cc131b53a3/build/overrides.mk#L41-L45

To build against GraphicsMagick, you can replace imagemagick with graphicsmagick in vips-all_DEPS: https://github.com/libvips/build-win64-mxe/blob/50edec409a6bfaf4f34300966dfdb2cc131b53a3/build/vips-all.mk#L11-L14

And use --with-magickpackage=GraphicsMagick while configuring libvips. This is now done automatically, see: https://github.com/libvips/build-win64-mxe/blob/8f930b90e7a02b279ae2b8b9093ff7128a418726/build/vips-all.mk#L89

Thank you for your guide. I have tried building against GraphicsMagick.

However, there is a linker error during building GraphicsMagick:

ld.lld: error: undefined symbol: xmlNanoFTPNewCtxt
>>> referenced by coders/.libs/magick_libGraphicsMagick_la-url.o:(ReadURLImage)

ld.lld: error: undefined symbol: xmlNanoFTPConnect
>>> referenced by coders/.libs/magick_libGraphicsMagick_la-url.o:(ReadURLImage)

ld.lld: error: undefined symbol: xmlNanoFTPGet

ld.lld: error: undefined symbol: xmlNanoFTPClose
>>> referenced by coders/.libs/magick_libGraphicsMagick_la-url.o:(ReadURLImage)

I have tried adding libxml2 libxml2-dev to Dockerfile, but it still produces this error. How do I solve this error?

It looks like that was fixed with commit https://sourceforge.net/p/graphicsmagick/code/ci/e05b8a44b22780e58bbe41127c703f3c37792538/.

I just updated and fixed the GraphicsMagick build with commit https://github.com/libvips/build-win64-mxe/commit/8f930b90e7a02b279ae2b8b9093ff7128a418726.

Thank you, I have successfully built with gm.

Now I'm trying to build against ImageMagick 7, and it gives me this error:

checking if libltdl package is complete... no
configure: error: in `/data/mxe/tmp-imagemagick-x86_64-w64-mingw32.shared.posix.all/ImageMagick-7.0.8-63.build_':
configure: error: libltdl is required for modules and OpenCL builds

and it seems the version is quite old.

I think upgrading ImageMagick to the latest version should fix that.

 # alternatively, one could build libvips with GraphicsMagick

Successfully built.

Though magickload doesn't behave exactly the same as installed imagemagick 7, but I guess it's on the libvips. Thanks again for your help!
