pgcc vs. gcc question - using <complex.h>

[Don Tucker]

Hello, I have the following test program that I can compile with gcc,
but when I try to compile with the portland group compiler, pgcc, I
get a stream of errors.

#include <stdio.h>
#include <complex.h>

int main(int argc, char **argv){
complex double a={2.3+1.4*_Com plex_I};
printf("a=%lf + i%lf\n",creal(a ),cimag(a));
return 0;
}

I am able to use <complex> instead, and use the C++ complex class and
compile with pgCC, but since I eventually want to pass an array of
complex numbers to a Fortran function, this method is not appealing.
Is there some compiler directive that I need to use in order not to
get all of the errors?

Is complex.h part of ISO C? If it's a gcc thing, you'd be better off
asking in one of the appropriate gnu newsgroups.

It's part of C99.

Don, what sort of errors are you getting?

No, it's all quite valid. The only problem is that it needs a C99
compliant compiler, which pgcc appears not to be. He would have
found out (I think) with gcc if he used -ansi -pedantic which
restricts to C90. He could also have used --std=C99 -pedantic and
had things work.

Minimum gcc flags for portability: -W -Wall -ansi -pedantic

Perhaps PGCC ships without a C99 library. Comeau C/C++ is advertised as
having "amazing C99 support," but is dependent on something like Dinkum
for full C99 support.

Both Comeau and Dinkum are commercial things and cost a little money.
Greg and PJ are apparently cooperating to provide a C99 compiler product
to those who want it. What's the problem with Comeau + Dinkum?

which makes it non-conforming for a hosted impementation.
