[Trilinos-Users] [EXTERNAL] FW: compiling Trilinos with clang and c++11

[Drake, Richard R]

Thanks Andrew, I saw that after I sent the email.  I think the clang install will have to be rebuilt, because just setting the PATH to a GCC 4.7.2 doesn't work (like it does for Intel).

Hi ​Richard,


This: "include/c++/4.4.7" implies the problem is the gcc compatibility. Looks like gcc 4.4.7 headers are being used. Min version for C++11 is 4.7.2. How to fix that depends on the system, but a start is to look at what gcc's are available on the system.

Does Trilinos build with clang?  I'm trying clang 3.5 with -std=c++11 but the configure fails in the C++11 probe.  The top of the CMakeFiles/CMakeError.log file shows this:
