Description

I maintain RMagick, the ImageMagick binding for Ruby.
To build the binding, it depends on CORE_RL_MagickCore_.lib.
Since ImageMagick-7.1.1-30, the installer no longer installs CORE_RL_MagickCore_.lib.
Therefore, our binding installation is no longer available....

Is it possible to get the CORE_RL_MagickCore_.lib installed again?

And ImageMagick 6 has same issue....

Thanks

We have removed the .lib files from the installer because you probably don't need those .lib files. I suspect that it is just being used to detect that ImageMagick is installed. I think you can fix this by tweaking the extconf.rb file. You don't need to link those .lib files those files are available as .dll files and should be referenced instead?

[Watson1978]

We are using C++ for bindings.
To resolve symbols for ImageMagick API when building source code, it requires the CORE_RL_MagickCore_.lib.

[dlemstra]

Those symbols are exported in the CORE_RL_MagickCore_.dll file. You should be able to reference those symbols with a dllimport instead?

[Watson1978]

Is the ImageMagick API interface immutable? It is a lot of work to keep up with every change, and we do not want to do it.

Previously, any changes to the interface would be noticed by an error at build time.

[dlemstra]

If you use a dllimport you are still using the same header files and this will result in a build error when the api changes. We don't change our API interface that often and when we do it will be a new method. You would need to do the same amount of work when you are using our .lib or .dll files. The only difference would be how the MagickCore library is linked.

OK, I try to change build proccess of our binding.
