Could you, please, be so kind to explain to me what these issues in the compiler output exactly mean (my compiler is pgi (pgc++) free version 17.4)?
Can you send the output of
pgaccelinfo
on your GPU machine, along with the
compile line you used that caused the problem?

The compiler output is:

How I configure my project: cmake …/src -DCMAKE_C_FLAGS=pgcc -DCMAKE_CXX_FLAGS=pgc++ -DCMAKE_CXX_FLAGS=“-acc -Minfo=all -ta=nvidia”.
I have one c++ source code file, which I configure.
What does this error mean?

Hi @and,
These are internal compiler errors (compiler bugs). Please send a reproducing example to PGI Customer Service (trs@pgroup,com) so we can investigate.
Thanks,
Mat
