a general issue. Our autobuild system ensures that git master and
v4-0-test always compile and test in at least Ubuntu 10.04, and it is
incredibly rare that it not work on at least Linux without it being a
specifically local issue.
You should ensure your module depends on glusterfs, by changing that to
+
+bld.SAMBA3_MODULE('vfs_glusterfs',
+ subsystem='vfs',
+ source=VFS_GLUSTERFS_SRC,
+ deps='samba-util',
+ init_function='',
+ internal_module=bld.SAMBA3_IS_STATIC_MODULE('vfs_glusterfs'),
+ enabled=bld.SAMBA3_IS_ENABLED_MODULE('vfs_glusterfs'))
adding deps='glusterfs samba-util' (and making that match what the
conf.check_cfg finds and stores).
I tried that. I added uselib_store='glusterfs' and included 'glusterfs' in deps= line. However while building I get this error:
[avati@blackbox samba]$ make
WAF_MAKE=1 python ./buildtools/bin/waf build

I am not familiar with waf, and trying to figure out how it works. I don't understand how the check_cfg() in wscript and source3/wscript_build's bld.SAMBA3_MODULE() actually integrate internally.

module. Instead, please just make it automatic based on finding
glusterfs.
OK, I will just leave things to check_cfg() detection then?

to make uselib_store='glusterfs' (not sure).
As mentioned above, I tried this but still get the dependency error. Not sure what I am missing..
