[Openmp-commits] [Openmp-dev] Large Refactor of CMake build system

[C Bergström]

My observation is that it's not consistently working and that's why
I'm even more upset and nervous about this change.

Further, "it works for me" is a very bad reason to go screw up a
stable branch and to continue to advocate that it so strongly.

The reason the release branch (before the merge commits) "works for
me" is because we have a wrapper cmake around the the project which
sets things correctly.
-------------
Here's what I see

>From cmake # Everything would appear to look good, right? (Also know
that it says g++, but in fact it's really pathcc.. I don't quite
understand that)
-------------------
checking whether we are using the GNU C++ compiler... yes
checking whether /opt/ekopath/bin/pathCC accepts -g... yes
checking whether g++ accepts -static-libstdc++ -static-libgcc... no
checking for gnatbind... no

....

and guess what happens during make
--------

------------

Lastly, thank you for testing with pathcc, but pretty please read the
instructions on the website. I'd strongly advise to update the date in
the URL and download a more recent version. Using 5.0.x is really old
and a significant number of fixes have been made since then - I
suspect this is the reason you may be seeing failures from the Release
branch (without the merged changes).
