Fails to build on opensuse 13.1

I had to manually modify the Makefile to continue.

Did you get something that works and passes tests? (make testall)

[dilawar]

Nope.

But I was able to compile (make) and install (sudo make install) it. I am not sure if I should trust this build.

[mschauer]

This is a 32-bit system? Then the test error is unrelated to your troubles with the build process.

[ivarne]

Can you find out what your $(ARCH) variable is set to? (eg change the error to $(error "unknown arch for openblas cross-compile ($(ARCH))"))

Also (unrelated comment), the standard way to change the make variables is to create a file named Make.user in the root of the repository. It will automatically be included and override the variables set in Make.inc

[dilawar]

"unknown arch i586 for openblas cross-compile". Stop

Hi dilawar,

Yesterday I could finally build Julia in openSUSE Build Service (see Issue #5920). However, the problem was related to KVM only and I have never seen your problem since I could always build Julia locally. You can check the rpm spec here https://build.opensuse.org/package/view_file/home:Ronis_BR/julia/julia.spec?expand=1

Maybe it can help you to fix your problem. Otherwise, you can try the package that I built and tell me if everything is working fine. Notice that I set the configurations to build Julia using systems' BLAS instead of openblas.
