I am new to dealii. I installed deal.II 8.5.0 using the dmg package from dealii website on mac OS Sierra. When I tried to configure I got this error:
CMake Error at /Applications/
deal.II-8.5-brew.app/Contents/Resources/brew/Cellar/cmake/3.7.2/share/cmake/Modules/CMakeTestCXXCompiler.cmake:44 (message):
The C++ compiler
"/Applications/
deal.II-8.5-brew.app/Contents/Resources/brew/bin/mpicxx" is
not able to compile a simple test program.
It fails with the following output:
Change Dir: /Users/vikramb/Documents/dealII/svn_co/deal.II/examples/step-1/CMakeFiles/CMakeTmp

make: *** [cmTC_5fce3/fast] Error 2
To workaround this I changed the CXX compiler option though ccmake. I was able to successfully configure and build. However when I ran I got this error:
make[3]: *** [CMakeFiles/run] Illegal instruction: 4
make[2]: *** [CMakeFiles/run.dir/all] Error 2
make[1]: *** [CMakeFiles/run.dir/rule] Error 2
make: *** [run] Error 2
Can anyone tell what I am not doing right?
Thanks,
