[rox-devel] fnmatch broken in gtk+

[Diego Z. <za...@ce...>]

Hi,

After banging my head against the wall for a while, I discovered that the 
fnmatch function (which tests to see if a filename matches a glob pattern) not 
only is included in gtk+, but it is broken.

fnmatch() is a standard function on Solaris (which I'm using), and I guess on 
Linux too. Gtk+ also includes it (arguably to have it even on systems where it 
does not exist), so when a program that uses fnmatch is linked against libgtk, 
it uses libgtk's version of fnmatch instead of the standard library's.

Unfortunately, the version of fnmatch included with Gtk+ is broken. It 
incorrectly matches slashes (/) with the asterisk (*), even when using the 
FNM_PATHNAME flag.

If your system has fnmatch (and assuming it works correctly), the workaround 
to this problem is to explicitly add -lc at the beginning of the libraries to 
link against. That way libc will be checked before libgtk, and the correct 
version of the function is used.

On my system, changing the following line in src/Makefile:

LDFLAGS = -L/usr/ceriaslocal/vfs/lib -R/usr/ceriaslocal/vfs/lib `${GTK_CONF
IG} --libs` ${LIBS} ${IMLIB_LIBS} ${VFS_LIBS}

to this:

LDFLAGS =  -lc -L/usr/ceriaslocal/vfs/lib -R/usr/ceriaslocal/vfs/lib 
`${GTK_CONF
IG} --libs` ${LIBS} ${IMLIB_LIBS} ${VFS_LIBS}

and recompiling fixed the problem.

I guess I'll be submitting a bug report to the Gtk+ folks soon :-)

Agh.
