Description Christian Walther 2006-02-01 08:39:52 UTC
I recently tried to get Samba 3.0.21a and 3.0.21b running on Solaris 9 several
times, using different build environments. The compilers in use where
Sun Forte Version 11 and gcc 3.4.2. The binaries where compiled for 64
bit, using CFLAGS="-m64" for gcc for example. I just used

configure --prefix=<path>

The core file analysis of the latest build shows that strlen() is called:

# mdb core

tried with latest SVN (rev 13772) on SLES9 x86_64, built as 64-bit, no problems.  I don't have access to a sparc box.  Any chance you can attach a level 10 debug log?

Output of the truss command while running net join...

truss is a command being used for debugging programs. It traces system calls and sends its' output to STDOUT.
Comment 4 Christian Walther 2006-03-02 07:53:38 UTC
After I received the bug update today, I compiled Samba again, this time using 3.0.21c. It didn't make any difference.

To make sure that my built environment is sane I removed gcc, and installed gcc 4.0.2 again. Compiler details (gcc -v):

Reading specs from /opt/csw/gcc4/lib/gcc/sparc-sun-solaris2.8/4.0.2/specs
Target: sparc-sun-solaris2.8
Configured with: ../sources/gcc-4.0.2/configure --prefix=/opt/csw/gcc4 --with-local-prefix=/opt/csw --without-gnu-as --with-as=/usr/ccs/bin/as --without-gnu-ld --with-ld=/usr/ccs/bin/ld --enable-threads=posix --enable-shared --enable-multilib --enable-nls --with-included-gettext --with-libiconv-prefix=/opt/csw --with-x --enable-java-awt=xlib --with-system-zlib --enable-languages=c,c++,f95,java,objc,ada
Thread model: posix
gcc version 4.0.2

I used the following set of environment variables:

export CFLAGS="-mcpu=v9 -m64 -D_LARGEFILE64_SOURCE=1"
export LDFLAGS="-mcpu=v9 -m64"
export PATH=/opt/csw/gcc4/bin:/opt/csw/bin:/usr/sbin:/usr/bin:/usr/ccs/bin
export LD_LIBRARY_PATH_32=
export LD_LIBRARY_PATH_64=

I found information on the net that gcc 4.0.2 contains a bug related to Solaris 64 binaries. So I added -pthreads to CFLAGS and LDFLAGS, as was advised. 
Didn't help either. :-(

Any chance you've tried this lately?  I still don't have a sun system..
Comment 6 Karolin Seeger 2009-12-02 04:18:08 UTC
Is that still an issue in Samba 3.4?
Comment 7 Jim McDonough 2010-03-04 19:44:38 UTC
no response in years..
