--- Comment #5 from PeteVine <tulipawn at gmail dot com> --- You're right, sorry for the confusion. It seems I skimmed over the wall of errors too quickly while the last one came from a different source file. According to my own results in bug #77730, I was somehow able to build the benchmark with earlier versions of gcc 6/7 using the -std=f95 flag. Could you try the following steps? wget http://www.phoronix-test-suite.com/benchmark-files/dolfyn-cfd_0.527.tgz tar xvf dolfyn-cfd_0.527.tgz cd dolfyn-cfd_0.527/src/ sed -i 's/F90FLAGS = -O2/F90FLAGS = -O2 -std=f95/' Makefile make
