Problem with 2d complex double array

Accelerated Computing HPC Compilers Legacy PGI Compilers
1

Hi,

the following code compiles fine with gcc 5.2, but does not with pgi 17.7 (using PGI_LOCALRC=/opt/pgi/linux86-64/17.7/bin/localrc.50200, i.e. pgi with gcc 5.2 compatibility):

  const int N = 5;
  std::complex<double> M[N][N];
  for(int i=0;i<N;++i){
    for(int j=0;j<N;++j){
      M[i][j] = 1.;
    }
  }

The compiler output is:

"/opt/pgi/linux86-64/17.7/bin/pgc++" -fastsse --c++11 -Minform=warn -o pgi_vs_gcc.C
PGCC-S-0073-Too many initializers for M (pgi_vs_gcc.C: 15)
PGCC/x86 Linux 17.7-0: compilation completed with severe errors

where line 15 corresponds to the statement std::complex M[N][N];

However, using double instead of complex neither gcc nor pgi complains. Also, not setting PGI_LOCALRC and using compatibility with a older version of gcc works.

Is this example not compliant with the standard or is it a compiler bug or anything else I am doing wrong?

Thanks,

I need a whole program. I do not see the point of guessing how you
filled in the area around the code fragment you sent.


In addition, I need to know what the default gcc is on your system, and
see the output dialog of
g++ -std=c++11 -v foo.cpp -c

then run it with the 5.2 g++

g++ -std=c++11 -v pgi_vs_gcc.cpp -c
then I want to see the output dialog

pgc++ -std=c++11 -v pgi_vs_gcc.cpp -c



It looks like you used “addlocalrc”. Did you originally
install the PGI compilers with a “Network Install”? If not,
using other gcc compilers for addlocalrc generated localrc will fail.

The whole program is

#include <complex>

int main(){
  const int N = 5;
  std::complex<double> M[N][N];
  for(int i=0;i<N;++i){
    for(int j=0;j<N;++j){
      M[i][j] = 1.;
    }
  } 
  return 0;
}

The output of the system compiler:

We have used a “Network Install” and so far haven’t run into any comparable issues with our real world code.
