Also, out of interest, has anyone else been able to compile statically using this package? I just get a long list of: cannot find -lopencv_stitching341... etc.

It works if I do it dynamically (i.e. not with the -static flag). Even if I point the compiler to the *.a files directly it still seems to compile dynamically, which is especially weird.

It also seems like there's a small mistake in the packages pkg-config file. If I run: x86_64-w64-mingw32-pkg-config --libs opencv

I get: -L/usr/x86_64-w64-mingw32//usr/x86_64-w64-mingw32/lib -lopencv_stitching341 ...

Although if I fix this path manually things still don't work :-(

Actually you need both packages in makedepends. If you're using an AUR helper you can easily have a situation where you have lapack but not cblas (as I did), because the lapack package is a split package. Users won't necessarily install the whole group by default.

@xantares, it is statically linked, it is needed only to compile not at runtime

xantares commented on 2018-05-03 06:56 (UTC)

then it should be in depends, not just makedepends

@billypilgrim, this error was fixed in this commit

3859586138f7

lapack (that contains cblas) is already a makedep since then.

I'm getting the following build error: make[2]: *** No rule to make target '/usr/i686-w64-mingw32/lib/libcblas.dll.a', needed by 'bin/libopencv_core341.dll'. Stop.

Anyone got any ideas?

edit: Heh, missing dependency. @maintainer would you mind adding mingw-w64-cblas as a makedep? Ta!

The failure I just mentioned goes away if you downgrade mingw-w64-gcc to 5.3.0-1. Please update your build time dependencies accordingly.
