fl_filename_list() in version 1.1.7 produces a file name list with empty names. 1.1.6 and prior work just fine.

   dirent **files;
   int num_files = fl_filename_list(m_directory.c_str(), &files);

OS: Gentoo Linux

Does the file chooser demo work?

Negative, Mike. Filechooser shows the empty filelist, and this is another machine already (P4 laptop).

Is the current directory local or a networked filesystem?

Local. I stumbled about the same thing just this second. When adding the trailing slash to filanems that are actually a directory, the list gets destroyed. I just can't figure out, how.

Also, local.

OK, I think I know what the problem is. FLTK is now by default compiled with the following symbols defined in the command line:
_LARGE_FILE_SOURCE
_LARGE_FILE_SOURCE64
_FILE_OFFSET_BIT=64

If FLTK is linked to an application that has these flags not set, the "dirent" structure is different and the filenames are swallowed (actually d_name is pointing at the wrong position).

Fixed in Subversion repository.

OK, since this broke binary compatibility in 1.1.x, I'm making the default to be --disable-largefile. If you use --enable-largefile, then fltk-config will also report the necessary definitions so that apps are compiled correctly.
