samba - Feb 2002 - Solaris 8, 64-bit compile problems with CVS SAMBA_2_2 as of 2002/02/05 16:13 EST

I've run into the following problems compiling the SAMBA_2_2 label
with Sun WorkShop 6, Update 2 as a 64-bit build

My configure line

CC=cc CFLAGS='-xtarget=ultra2 -xarch=v9a' ./configure 

1. 64-bit swat is still broken because the crypt function isn't
   prototyped correctly. I first report this in April 2001

   http://marc.theaimsgroup.com/?l=samba-technical&m=98708044014344&w=2

   I had some private correspondence with Jerry Carter about this. THe
   workaround was to add CPPFLAGS="-D__EXTENSIONS__"

   I pursued this with Sun and eventually found it as a bug in the
   crypt man page. The man page says to include unistd.h. You should
   include crypt.h instead. /usr/include/crypt.h exists on Solaris
   2.6, Solaris 7 and Solaris 8. I don't have access to earlier
   versions of Solaris to check.

   This could probably be handled by configure.


2. 64-bit build fails on libnss_winbind

   so
   make: *** [nsswitch/libnss_winbind.so] Error 1

After changing the rules in the Makefile, I see

cc  -h nsswitch/libnss_winbind.so -G -o nsswitch/libnss_winbind.so
nsswitch/winbind_nss.po nsswitch/wb_common.po nsswitch/winbind_nss_solaris.po

ld: fatal: File processing errors. No output written to
nsswitch/libnss_winbind.so
make: *** [nsswitch/libnss_winbind.so] Error 1

The problem is that the CFLAGS='-xtarget=ultra2 -xarch=v9a' need to be
included in the command line. It seems like this should probably be
done for most shared libraries, or at least when SHLD=${CC}. This is
probably the *WRONG* thing to do for HP-UX, perhaps CFLAGS needs to be
included in LDSHFLAGS. I'll let other more familiar with the platforms
make the best decision.

Here's a potential patch

The prototype mismatches seemed be cause by function calls using
size_t as the type for buflen when the function prototypes specify
"int *buflen".
