Pgi compiler Error: "shared_ptr" is ambiguous

Hello, I’m trying to compile some software package named “xios” with fcm. And it compiles well with g++, but I could not make it work with pgi compiler. I got the following error.

“/usr/local/xios-2.5/inc/object_template.hpp”, line 85: error: “shared_ptr” is
ambiguous
shared_ptr getShared(void) ;

Hi y.juntao,

While I’m not familiar with XIOS, I did find the source from this page: https://forge.ipsl.jussieu.fr/ioserver/wiki/documentation

I copied the “arch-GCC-LINUX” files to a “PGI” version, then updated the fcm file to include the flags you have above and configured it to use Boost 1.68. I’m using nvc++ 20.5 and have it configured to use the GNU 9.2 STL. For good or bad, the code compiles fine for me.

What pgc++ version are you using? What GNU STL version do you have it configured to use (by default it will use the system GNU)? What version of Boost are you using?

I can try again to reproduce the error once you give more details, but I suspect that you’re configured using an older GNU (like 4.8.5) which did not fully support C++11. You might try again on a system with a newer GNU, such as 4.9.3 or later. Though you may need a newer Boost version as well.
