RE: alphasort on HP-NonStop

[Joachim Schmitz]

Hi Bruno

Hmmm, as per config.log and config.h configure apparently found alphasort and 
#defined _HAVE_ALPHASORT, I wonder why?

configure:24953: checking for alphasort
configure:24953: cc -o conftest -g -I/usr/local/include  conftest.c  >&5
    return 0;
    ^
"/usr/local/Floss/gnulib/testdir-posix/conftest.c", line 302: warning(203):
          statement is unreachable


configure:24953: $? = 0
configure:24953: result: yes


Looks like a severe problem with my /usr/local/bin/cc wrapper script, using 
/usr/bin/c89 directly makes the linking fail, as it should.

Ah! Found it in a lib called zutildll! And that indeed  gets linked by my 
wrapper script. It is not documented anywhere, so I'm not sure whether it 
serves the purpose POSIX defined for this...
Not sure whether I'd need to do an #undef HAVE_ALPHASORT or just add it's 
prototype and where to do any of this.

I need to have a deeper look later, probably after X-mas.

Bye, Jojo

PS: Merry Christmas and a Happy New Year to all of you!

You mean add alphasort to gllib/dirent.in.h?

We don't have an alphasort elsewhere
And yes, we're quite a bit behind the current POSIX...

Gnulib has an 'alphasort' module that provides a replacement when the function 
is missing. The error message here makes me think that the function exists on 
your system but its declaration is missing.

Can you add the declaration to <dirent.h>?
