Using ImageMagick with a 32-bit Qt/C++ app built on Windows 10 using MinGW

Post by smoyer » 2018-05-02T06:52:53-07:00

I have a 32-bit Qt/C++ app built on Windows 10 using the MinGW compiler, and I want to start using ImageMagick APIs with this app.

I tried to use the ImageMagick-7.0.7-29-Q16-x86-dll.exe Windows binary release and discovered that dlls built with MSVC are not compatible with MInGW binaries.

I then downloaded the ImageMagick-i686-pc-mingw32.tar.gz binary release listed under Unix Binary Releases and am getting unresolved reference errors:

Any recommendations on how I can do what I want to do?
