Problem building Python 2.5.2 curses module on HP/UX 11.11

[Mike Kent]

I'm having a problem building the Python 2.5.2 curses module on HP/UX
11.11 using gcc 3.3.6, and was hoping someone had a solution.
Compiling Modules/_cursesmodule.c is giving several warnings, but no
errors. The relevant compile/link output is below. The key output
line is:

*** WARNING: renaming "_curses" since importing it failed: dynamic
module does n
ot define init function (init_curses)

So, given that there are no actual errors during the compile, and the
warnings are probably benign, does anyone know what would cause the
resulting compiled module to NOT have the init function?

Full build output:

So, given that there are no actual errors during the compile, and the

warnings are probably benign, does anyone know what would cause the
resulting compiled module to NOT have the init function?

Can you do nm(1) on the module? It's now called _curses_failed.sl
