[Trilinos-Users] [EXTERNAL] Re: Compilation fails on OSX with clang

[Phipps, Eric T]

I think this was due to changes in Tribits and was fixed in at least the development branch.

Ross:  did your DEPLIBS fix for Sacado get applied to the 11.12 release branch?

Thanks for the information. When building 11.12.1 with both clang and gcc 4.9.1 I get the error described here:

Hello,

Over at https://github.com/Homebrew/homebrew-science/issues/887 we're trying to write a solid Homebrew (https://brew.sh) formula for users to install Trilinos on OSX.

We haven't been able to build 11.12.1 so far and thought it might be safer to focus on 11.10.2. The build goes through with gcc 4.9 but it fails with clang with the following error:

It would be great if seasoned Trilinos users/devs chimed in on the thread above to comment on the formula and perhaps help us resolve build errors. This would make Trilinos widely available to OSX users.

Cheers,

Dominique
