Some questions. (I don't know the answers and the questions may be idiotic -
especially given that I've never used Solaris.):
Are you sure that you're using gcc ? The compiler reports 'cc' ,and whilst
that may just be an alias for 'gcc', I would expect that on a Solaris box,
it could really *be* cc. Does /usr/include contain gcc's header files or
does it contain cc's header files ?
make clean
perl Makefile.PL CC=gcc
make
How does 'crypt.h' get #include'd ? And why does crypt.h declare
'des_crypt' ? On my linux box, /usr/include/crypt.h contains no mention of
'des_crypt'. (I don't think 'crypt.h' is even being #include'd, but I'm not
sure. It's certainly not being #include'd on my Win32 box, because there's
no such file.)
I would probably try something ghastly and unrecommended - like
*temporarily* replacing every occurrence of 'des_crypt' in 'crypt.h' with
some other term (eg '__des_crypt'). Then start again with:
make clean
perl Makefile.PL (with 'CC=gcc' if necessary)
make
If 'crypt.h' is not *really* needed, then that would probably work. But if
'crypt.h' really *is* needed, and if 'crypt.h' really *does* need to
declare 'des_crypt', then it may not work :-) In that case I think you'd
have to look at renaming 'des_crypt' to something else within the
Crypt::DES source files.
If you do make changes to 'crypt.h', don't forget to undo them once you've
finished. (Best to save a backup copy of 'crypt.h'.)
Cheers,
Rob
