When not using + default clause or when using default(shared), this makes no difference, but + if using default(none), previously the choice was not specify the const + qualified variables on the construct at all, or specify in firstprivate + clause. In GCC 9 as well as for OpenMP 4.0 compliance, those variables need + to be specified on constructs in which they are used, either in shared or + in firstprivate clause. Specifying them in firstprivate clause is one way to + achieve compatibility with both older GCC versions and GCC 9, + another option is to drop the default(none) clause. + + This patch thus drops the default(none) clause. + + See https://gcc.gnu.org/gcc-9/porting_to.html#ompdatasharing + + Signed-off-by: Robert-André Mauchin <zebob.m@gmail.com> + +diff --git a/intern/elbeem/intern/solver_main.cpp b/intern/elbeem/intern/solver_main.cpp +index 68f7c04cd54..514087b6130 100644 +--- a/intern/elbeem/intern/solver_main.cpp ++++ b/intern/elbeem/intern/solver_main.cpp +@@ -381,7 +381,7 @@ LbmFsgrSolver::mainLoop(const int lev) + GRID_REGION_INIT(); + #if PARALLEL==1 + const int gDebugLevel = ::gDebugLevel; +-#pragma omp parallel default(none) num_threads(mNumOMPThreads) \ ++#pragma omp parallel num_threads(mNumOMPThreads) \ + reduction(+: \ + calcCurrentMass,calcCurrentVolume, \ + calcCellsFilled,calcCellsEmptied, \ +@@ -1126,7 +1126,7 @@ LbmFsgrSolver::preinitGrids() + GRID_REGION_INIT(); + #if PARALLEL==1 + const int gDebugLevel = ::gDebugLevel; +-#pragma omp parallel default(none) num_threads(mNumOMPThreads) \ ++#pragma omp parallel num_threads(mNumOMPThreads) \ + reduction(+: \ + calcCurrentMass,calcCurrentVolume, \ + calcCellsFilled,calcCellsEmptied, \ +@@ -1164,7 +1164,7 @@ LbmFsgrSolver::standingFluidPreinit() + GRID_REGION_INIT(); + #if PARALLEL==1 + const int gDebugLevel = ::gDebugLevel; +-#pragma omp parallel default(none) num_threads(mNumOMPThreads) \ ++#pragma omp parallel num_threads(mNumOMPThreads) \ + reduction(+: \ + calcCurrentMass,calcCurrentVolume, \ + calcCellsFilled,calcCellsEmptied, \ |
