And about this package, I've splitted it into mxnet{,-cuda,-mkl}. And it will take lots of time and space to compile.

The pre-built binaries of mxnet{,-cuda,-mkl} and their dependencies can be found in arch4edu.

You learn something new every day. Building in a chroot environment definitely helped to resolve dependency issues. I did not know about that either. I really appreciate your feedback, thank you! The PKGBUILD should be updated to work correctly now.

No, you will get: /usr/bin/ld: cannot find -lcuda if you build it with a clean chroot enviroment. See more: https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_Clean_Chroot (I'm using a modified extra-x86_64-build to have cudnn in my custom repository)

Why would I need to add that to ldflags? Everything builds fine without it.

Thanks for reply. I'm not familiar with mxnet so I trust your decisions. And one more thing needs fixing in PKGBUILD: please add echo "ADD_LDFLAGS = -L/opt/cuda/lib64/stubs" >> config.mk in prepare() for "-lcuda"

@petronny I recall that libmxnet.so is linked to libmklml_intel.so and does not check for libmklml_gnu.so which I prefer. While my approach works, it might not be entirely correct. Removing -j$(nproc) is resonable, I didn't know you could set it in the makepkg config file. And wget should be in the makedepends. I could look into optdepends and different blas versions. In the current version of mxnet I dont think you can use intel-mkl together with mklml, which gives a huge performance benefit at least on my computer. Since I dont use any of hadoop, caffe or torch I can't really add the feature to the PKGBUILD since I have no way of confirming that it works. You can add it yourself if you need it, and send me a git diff and I will push it.

Is line 59: install -D "$srcdir/mklml/lib/libmklml_gnu.so" "$pkgdir/usr/lib/libmklml_intel.so" correct? And I think you can remove the -j$(nproc) option in line 53. It should have been set in /etc/makepkg.conf. And wget should be in the makedepends cblas, openblas-lapack, atlas, intel-mkl should be detected and set in prepare(), and added to optdepends hadoop, caffe, torch should be added simliarly to opencv Please fix the PKGBUILD. PS. you can find some compiled packages, such as hadoop, caffe-git, torch in https://mirrors.tuna.tsinghua.edu.cn/arch4edu/
