Unable to run pgprof in ArchLinux

Accelerated Computing HPC Compilers Legacy PGI Compilers
#1

Hello,
I just installed the PGI Community Edition compilers in my ArchLinux computer (kernel: 4.13.8-1-ARCH, gcc: 7.2.0, glibc: 2.26-6, PGI: 17.10-0 64-bit)

Installation went without trouble, but as far as I have started trying to use the compilers I see the following problems:

  1. I cannot compile a C++ simple code.
[angelv@comer 00-original]$ make
pgc++ -fast -Minfo=all,ccff main.cpp -o cg.x
"/usr/include/bits/floatn.h", line 61: error: invalid argument to attribute
          "__mode__"
  typedef _Complex float __cfloat128 __attribute__ ((__mode__ (__TC__)));

^

  1. The same version of the code, but in Fortran compiles and runs with no issues, but if I try to run the resulting executable from inside the profiler I first get this message when trying to “Open a New Session”
[angelv@comer 00-original]$ pgprof
Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /home/angelv/.eclipse/org.eclipse.platform_4.4.1_1739789791_linux_gtk_x86_64/configuration/org.eclipse.osgi/12/0/.cp/libvp_linux_x86_64.so whic\
h might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

Despite the message I can run the code and when finished I get information in the CPU Details tab, but double clicking in any of the functions never opens the source files. In the console I get the following:

Any idea how to solve these issues?

Many thanks,

It is a known issue that PGI compilers do not support gcc 7.2.
We are working on it.

See http://www.pgroup.com/resources/docs/17.10/x86/pgi-release-notes/index.htm

for information on which gcc/glibc versions we support.

OK, thanks.

I have now moved to another platform (FC26), where the issue with float128 does not show, but I’m still unable to open the source code files inside pgprof.

Any ideas if that can be solved?

Thanks,

#4

what is the output of

gcc --version ??

If it is 7.anything or 8.anything, it is not supported.

I am assuming FC26 is Fedora 26, which is gcc 7.2.
