gmsh @2.8.4: error: read-only variable is not assignable

[dershow]

I just upgraded to OS 10.13 and migrated. Now gmsh will not build. However, I tried to xcode-select to use xcode 8.3.3 and that does allow it to build. So, it fails with 9.1

Could you attach the main.log, please?

[dershow]

I had to uninstall and rebuild, since I had gotten it to install with Xcode 8.3.3. It is attached.

[ryandesign (Ryan Carsten Schmidt)]

Confirmed with Xcode 9.0.1 on Sierra.

Looks like the gmsh port hasn't been updated since 2014, and there have been many releases of gmsh since then. Maybe this issue would be fixed by updating the port to a newer version.

Note that Xcode 8.3.3 is not meant to work with High Sierra. If it worked for compiling gmsh, great, but you shouldn't leave it selected because it will probably cause other ports to fail to build.

Thanks. I had some other code that won't build with Xcode 9. Openmodelica, that uses macports, but has its own repository. So, I had downloaded the old Xcode, and just used Xcode-select to use it for a bit. In that case, it seems to be an issue with pthread that I have found on a few other projects with the switch to Xcode 9.

3.0.6 seems to build fine but I get this link error on HS

While building 3.0.6 under Sierra (Xcode 9.1), under trace mode, I also see the same error, along with

sh: /bin/ps: Operation not permitted

Without trace mode the linking succeeds.

I don't get the same /bin/ps error when upgrading to 3.0.6 so I'm hoping that's fixed with the newer release. However, I do run into the same problem @kurthindenburg ran into with an invalid link command. It seems just re-running the exact same command succeeds, though, making this a bit more difficult to debug.

[seanfarley (Sean Farley)]

update to 3.0.6 -- errors with linking

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #55678.

[ryandesign (Ryan Carsten Schmidt)]

gmsh was updated to version 4.0.0 in [b75bfd254a4d9783a3b58df2a95d7daf69f011e2/macports-ports]. Does that work for you?

[dershow]

Yes, it does now work. Thank you.
