-Subject: [PATCH] Check for OpenMP version at configure time
|
|
|
-
|
|
|
-Only accept OpenMP >= 4.5, due to the "priority" clause that we use
|
|
|
-since commit 6f6f5e7, and also document that in the INSTALL file.
|
|
|
-
|
|
|
-If explicitly required with --enable-openmp, fail configuration if the
|
|
|
-version is not available.
