Hi guys,
The issue persists on my arch box, and converting the matrix from
sparse to dense takes up too much memory. Are there any temporary
workarounds, while waiting for the upstream fix?
The bug seems to be in Arch rather
Might be a good idea to package OpenBLAS for Arch, if you can't find an
existing PKGBUILD.

There is an AUR pkgbuild, but since Julia is in community we can not depend
on that. But yeah the system BLAS seems to be at fault. I added the Arch
maintainer of Julia to the conversation.
@Alexander.
There seems to be an issue with the BLAS implementation for Julia. Would it
be possible to
Ok, so here is the output from versioninfo() from inside the Julia REPL:

So building it from the PKGBUILD leads to the same error. I am now building
it with the same make options from the tar.gz on the Julia download page.
Andrei we probably have to build other parts that interact with suitesparse
from source instead of using the Arch ones. But if the problem

Make the problem go away. So it is the interaction between the system
blas/lapack and the built suitesparese. Are there any patches that julia
carries over suitesparse 4.4.1?

So I narrowed it down to combining the system's blas with Julia's
suitesparse. In the tests I made laplack has no influence. Should I file an
issue against Julia or with the Archlinux package? What are the Fedora
packages bundling?

I think the problem here is that we might be using something that requires
a certain version of BLAS or LAPACK, or possibly a patched LAPACK or
something. We get a patched LAPACK when we build OpenBLAS. I've directly

Hi all,
I recently upgraded to Julia Version 0.3.3 on my Arch Linux box and
sometimes get this strange error, followed by a kernel crash - what gives?
julia: symbol lookup error: /usr/bin/../lib/julia/libcholmod.so: undefined
symbol: zpotrf_
//A
You may need to clean and rebuild the dependencies as well as core Julia.

Ah, yes. If you haven't, try a `make -C deps distclean arpack-julia
distclean-openblas distclean-suitesparse`, then `make cleanall` and finally
`make`.

Where do i need to type all this? I must mention that I did not compile Julia
from source, but used my distribution's (arch linux) package manager (pacman).

A fellow archuser here. Under which circumstances does the error occur? Eg.
what code are you executing?
And what does
pacman -Qi julia blas lapack

If you didn't compile, then ignore my second message and Joao's. Running
`versioninfo()` from the julia prompt will give some information about your
system configuration, and Valentin's question, (running `pacman -Qi julia
blas lapack`) will be helpful to know the answer to as well.
