PGI’s preprocessing shows odd behavior.
$ pgcc -E main.c
Works, but omits file information from the preprocessing (from which file a declaration came) (pgcc -### -E foo.h also yields a completely different call than for main.c)
$ pgcc -E foo.h
We want this file information (and intel and gcc supply it)
$pgc++ -E main.cc
Fails, with error:
PREPRO-F-0206-Can’t find include file iostream (foo.hpp: 1)
PREPRO/x86-64 Linux 16.4-0: compilation aborted
(And again $ pgc++ -### -E foo.hpp looks very different from main.cc)
$ pgc++ -E foo.hpp
Although the four files have the same content, the preprocessor is invoked differently.
- It doesn’t give file information for headers
- It fails for a c++ header
Gcc, and intel are fine with this.
Personally, I can’t see the reason why this difference exists.
We don’t really want to add a workaround for our tool to rename a file, just because one compiler can’t preprocess headers.
Is this intended, or should I file a support request / bug?
Thanks for your help and best regards,
