Hello,

I tried to build Samba today (using an automatic Debian package builder called "pdebuild"). However this resulted in a compiler error.

pbuilder: Failed autobuilding of package


It took me quite a while to figure out what caused the problem. The problem was that I explicitly specified the linker flags (LDFLAGS) as "-Wl,-z,defs" (which is the default for this package builder). No specifying the flags "solved" the problem although I think that there shouldn't be any undefined references in the source, should they?

Regards

that's normal for a vfs module. It wouldn't be normal for a library however :-)
