Hi,

Thanks for the report. I do not have access to macOS Mojave, so I won't be able to reproduce the error and fix it. Maybe one day Homebrew will include Scotch in core, right now, you can skip the library installation (it you do not plan to use Scotch decomposition.)

Hi,
Thanks for the response.
How can I install this library manually, is there any other option?
I have tried a couple of times to install version 5.0 and 4.1 but the compilation stopped at some point. Not same location in both cases. Mixing scotch has to do anything with that ?
I followed the instructions as mentioned for here
https://github.com/mrklein/openfoam-os-x/wiki/OpenFOAM(R)-release-&-Homebrew
Also, the version numbering needs to be updated in your guide. The 5.0 is 5-0 on OpenFOAM server if the new download is required.

just wondering, do you have a reason to go through the painful self compilation instead of using the docker containers? They should have all libraries required. I am using the docker containers successfully on macOS 10.13.6 (High Sierra), but don't see a reason why they shouldn't work on Mojave, as that's the idea of container-ization.

[aqeelahmed168]

I am already using docker. I though direct compilation would create an environment like we get in Linux. Able to directly run through terminal and use multi presserros.

[mrklein]

@aqeelahmed168 I need more details. Theoretically missing Scotch should not interfere with compilation (as build scripts check library availability and skip corresponding part if library is not installed). Could you post the error message?

Concerning initial error, since in fact it is not a problem of compilation, but a problem of running tests, maybe you can remove tests from scotch formula (comment out everything between test do and corresponding end in scotch.rb).

brew install scotch --without-check

[matteoicardi]

same problem here, everything compiles, including scotch with this link [https://raw.githubusercontent.com/jslee02/homebrew-core/3ec5109c8d7bddb6631e9b76f3c540d66f61357f/Formula/scotch.rb],
but then decomposePar and all other parallel utilities give me "section not supported" on the scotch dylib

[mrklein]

I have pushed 13ee435 to address the issue. Could you test formula file?

[AleksZhuravlyov]

@mrklein, I had scotch, which was installed as "brew install scotch --without-check". I've made "brew remove scotch" and "brew install scotch.rb" using 13ee435 and scotch was installed without errors.

[mrklein]

@AleksZhuravljov, Thank you. Did you have problems with scotch decomposition, described by @matteoicardi ?

[AleksZhuravlyov]

@mrklein I didn't. I guess it can depend on the solver which is used. And I actually don't use parallel utilities. I can test a project where can be such a problem if you pick up one.

[mrklein]

@AleksZhuravljov: well, if you do not decompose a case, you should not encounter the error. Let's wait for someone, who does decompose their cases.

[matteoicardi]

Thanks @AleksZhuravljov , it works now!

[mrklein]

Since, it seems, formula works now, closing the issue.
