Hi,

the "test/fc_omp " is crashing due to:

ilias@adf1:~/Work/programming/autocmake/test/fc_omp/build-2017-05-18-22-22-53/.cmake ..

Thanks Miro - can you try a later CMake version? Not sure which exactly but with latest it should not fail anymore.

Hi,

I installed cmake3 package (CentOS 7), but how to activate it for autocmake without manually introducing links ?

cmake3 is fine, see:

OK I think we should bump the minimum version in tests to 3.0 - do you agree?

miroi commented 7 years ago

Fine; let's demand cmake3 for this test.

But how to quickly arrange it on CentOS 7 where cmake2 is the default ?

bast commented 7 years ago

It should be relatively simple to install (download) the latest CMake also on CentOS 7. I am closing this but please re-open in case the issue is difficult to solve.
