VFS Linking errors

[Paul Weaver]

After successful tests on a linux machine, we're trying to deploy a VFS module onto a solaris x64 machine.

Initial problem was we couldn't compile. Downloaded the source for 3.0.28, ran through configure and make. The VFS object compiled fine, but then wouldn't connect

/usr/sfw/sbin/smbd --version
Version 3.0.28

[2008/09/18 15:18:26, 0] smbd/vfs.c:(66)
  Failed to register vfs module.
  The module was compiled against SMB_VFS_INTERFACE_VERSION 134502736,
  current SMB_VFS_INTERFACE_VERSION is 21.
  Please recompile against the current Samba Version!


So we removed the prepackaged samba completely and installed 3.0.28 (the version we'd tested on on x86 linux)

/usr/local/samba/sbin/smbd --version
Version 3.0.28

and recompiled the vfs module

We could then connect to the server, but then hit a snag
ld.so.1: smbd: fatal: relocation error: file /usr/local/samba/lib/vfs/media_harmony.so: symbol __unsafe_string_function_usage_here__: referenced symbol not found

The compiled version seems fine, aside from this vfs module. 

Now I understand that this function is defined in safe_string.h. It compiles fine, appears to link fine

/usr/sfw/bin/gcc -c -g -O2  -fPIC -Iinclude -I/export/home/npf/mediaharmony/samba/samba-3.0.28/source/include -I/export/home/npf/mediaharmony/samba/samba-3.0.28/source/popt -I/export/home/npf/mediaharmony/samba/samba-3.0.28/source/lib/replace -I/export/home/npf/mediaharmony/samba/samba-3.0.28/source/lib/talloc -I/export/home/npf/mediaharmony/samba/samba-3.0.28/source/tdb/include -I/export/home/npf/mediaharmony/samba/samba-3.0.28/source/smbwrapper -I/export/home/npf/mediaharmony/samba/samba-3.0.28/source/librpc -I/export/home/npf/mediaharmony/samba/samba-3.0.28/source -I. media_harmony.c
/usr/sfw/bin/gcc -shared  media_harmony.o -o media_harmony.so 
~/mediaharmony $ echo $?
0


I assume it's because I'm compiling with gcc, and Solaris isn't GNU. I've looked at running crle and added the gcc library to no avail
bash-3.00# crle

Configuration file [version 4]: /var/ld/ld.config  
  Default Library Path (ELF):   /usr/sfw/lib:/lib:/usr/lib
  Trusted Directories (ELF):    /lib/secure:/usr/lib/secure  (system default)

Command line:
  crle -c /var/ld/ld.config -l /usr/sfw/lib:/lib:/usr/lib

As far as I can see strncmp seems to work fine (the opendir function works), the error occurs with strcmp -- smbclient works fine and I assume that uses strcmp. I'm not a C programmer, so I'm not keen on the idea of swapping strcmp with strncmp if there's a better way.

Any ideas?
