pgcc version inconsistencies

Accelerated Computing HPC Compilers Legacy PGI Compilers
#1

I compile the following example code using both pgcc 11.4 and 12.3:

#include <stdio>
#include <float>

int main ()
{
  printf("DBL_MIN = %e\n", DBL_MIN);
  printf("DBL_MAX = %e\n", DBL_MAX);

  return 0;
}

pgcc Version 11.4 is successful:

I do not know if this is a problem with our installation of 12.3 or is a bug. Any help is appreciated.[/code]

I thought at first that your mistake is leaving out the “.h” extension to the header files. But after typing my reply I discovered that this wonderful forum removes the extensions inside the code tags.

So assuming you actually did include the <stdio.h> and <float.h> headers correctly, I was able to compile this test code with no errors using PGI 10.9, 11.1, 12.1 and 12.4. They all gave the same answer as well.

I did include the .h extensions in test code. Interesting that the forum software hides them.

Thanks for the feedback. I will look into a faulty installation of the compiler.
