5 years ago @huihut No. I've got a mingw toolchain from an Arch repo which orignates from the (now-removed) official repo. I don't want to setup and build toolchains or opencv myself. I'll appreciate if you can provide a 64bit one.
@dongrama I don't care about versions as long as it works, and I assume that 3.4.x will work for me (even it doesn't work, I can change my code to adapt. I'm doing simple image template matching).
I've got the 32bit to link finally (using panic=abort). I don't know if it will work correctly because I'm still working on the code.
Edit: I'm cross-compiling from Linux.

5 years ago @lilydjwg I just tried to compile opencv3.4.1 for you using MinGW-w64, but the following error occurred. And I can't solve it now.

(I've taken a look at cross-compiling opencv, and it seems harder and more unclear than a GNU autotools build system. Also it seems that there are lots of dependencies to build.)

5 years ago Oh! It's the wrong annotation of the aviriff.h file. It's compiled now. The configuration is as follows. I uploaded to repo later

-----------------------------------------------------------------It worked, thanks!
I'm mainly targeting x86_64-pc-windows-gnu these days. And I get linking errors from rust with the 32bit due to the eh vs sjlj difference.
