I've had the same issue as @domanov. Build fails during python setup.py build with segmentation fault. Any suggestions what can be done to narrow this down?

Hi, @domanov I can't reproduce your problem. You can install the binary build from https://mirrors.tuna.tsinghua.edu.cn/arch4edu/

Hi, I am not able to compile mxnet, it fails with segmentation error at the end when python setup.py
PKGBUILD: line 39: 17500 Segmentation error (core dump created) python setup.py build
Any hints?

It's strange. In my system the build is successful. If I remove cblas or -lcblas flag, I get the same error on 'cblas_ssyrk'. readelf -Ws /usr/lib/libcblas.so | grep cblas_ssyrk confirms that the symbol is there and I believe the linking should be sucessful.

I have cblas and blas installed, still get the cblas_ssyrk error.

I guess you might not install cblas package. In Arch blas (libblas.so) is a fortran library and cblas (libcblas.so) is a C library. libcblas.so from cblas package contains the symbol cblas_ssyrk and may solve your build problem. For the dependency, you are right. I had some trouble with openblas and numpy and I thought that it was a dependency problem. But it was my mistake and is not a dependency problem.

I get
ld: build/src/operator/tensor/la_op.o: undefined reference to symbol 'cblas_ssyrk'
/usr/lib/libcblas.so.3: error adding symbols: DSO missing from command line
with USE_BLAS=blas ADD_LDFLAGS=-lcblas USE_LAPACK=1.
So I use openblas-lapack to build the package.
And openblas-lapack doesn't break dependencies.

Cuda 9 does not support gcc 7 which is the default gcc in the current Arch linux. So we need gcc-6 as a dependency and flags CC=gcc-6 CXX=g++6 to compile the package.
Why openblas? The blas package in the official repository should be used (USE_BLAS=blas ADD_LDFLAGS=-lcblas). Openblas breaks several dependencies of the standard packages such as python-numpy. If one really needs openblas, it could modify the PKGBUILD and do appropriate preparations. This must be optional and the standard blas must be the default.

Eventually I think it could be a good idea to extract the mklml library to its own AUR package, and make it an optional dependency for this one.

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.
