I used a very simple hello.c program as listed below and tried compiling with pgcc.
It gave the following warning:
PGC-W-0156-Type not specified, ‘int’ assumed (hello.c: 2)
PGC/x86-64 Linux/x86-64 6.2-4: compilation completed with warnings
The PGI version I’m using is:
pgcc 6.2-4 64-bit target on x86-64 Linux

Is there any clue? Thanks.
