pthread_* required on hpux10.20 on C++?

[Marco Manfai Yu <yumf@Ultimatech.COM>]

Hi,


    I've downloaded and built gcc 2.95.1 with standard as and ld. When
I compile a C++ program the linker complains about missing symbols
that start with pthread_. I don't use any threads in my code.
nm shows that libgcc.a contains unresolved reference to
pthreads. Am I missing something during configure or make?
I tried --disable-threads on my configure line but it doesn't seem to
do anything.

Any pointers or help is greatly appreciated.

Thank you,

Marco Yu

The following is my configure line and the C++ source code

Here's my C++ source code.


#include <iostream>

int
main (int, char**)
{
    unsigned k[] = { 10, 10 };
    cerr << k[0] << " " << k[1] << endl;
}
