Further investigation revealed this was just me being stupid and running out of space in /tmp, so the check() function couldn't create /tmp/rand.dat. Sorry about the noise, everything seems to work fine now.

Can you try cloning the repo for this package and building somewhere other than tmp?

AsmundEr commented on 2017-04-03 11:29

To be specific, I am installing using yaourt, and the check() function failed saying

./test_common_random /tmp/rand.dat 0
ERROR: main: cannot replay random sequence

Is this just a file it can't find during testing?

What does the check function do? I know the maintainer of scotch was receptive to improvements in the build system. I already pointed him at all the hacks in the PKGBUILD...

AsmundEr commented on 2017-04-03 11:27

I may have just cracked the riddle: when it failed for me, it first failed in the check() function saying "cannot replay random sequence". So I commented that out, and restarted the build, upon which it gave the error message mentioned on 2017-03-29. But now I tried a fresh build where I commented the check() out before the first build, and it now works fine!

For me, SCOTCH_archInit is defined in "src/scotch_6.0.4/src/libscotch/library_arch.c".

Ah right. I have nothing to do with "scotch_esmumps" nor "OpenFOAM". But, I did help maintain this package because it was a bit broken before, and I used OpenFOAM 3.x for a while.

I just tried building the package again and it is working for me. That's odd. I looked for the specific line you quoted, and I have it, and it works fine.

What version of GCC are you using? Is your system up to date?

AsmundEr commented on 2017-04-03 10:53

@ioquatix When I tried to install OpenFOAM, I had scotch installed from an old package "scotch_esmumps" that provides "scotch", so when OpenFOAM PKGBUILD checks "is scotch provided?" the answer is "yes", but then their PKGBUILD calls "pacman -Q scotch" to get the scotch version, and that command fails and stalls the build.

What details do you need about my system? It is an up-to-date 64bit Arch box with Intel Core i7-3770, 32 GB memory.

@AsmundER Thanks for the update. Please report problem to OpenFOAM and let me know what happens. This package is called scotch, so I'm a little bit confused about the problem you are having.

I have not seen that error before. Can you provide some more details about your system?

I also had a "scotch problem" when installing OpenFOAM, which led me here. It's not actually a problem with this package, but with OpenFOAM trying to determine the scotch version by using `pacman -Q scotch`. This obviously fails if the user has installed a package that is not named "scotch" but provides scotch. I will report the bug on the OpenFOAM package.

As for building this package, I have not been able to get it to work, it fails at:
