| Under Linux it is not possible to build any application with the bundled image libs with Xft because libXft.so is linked to a shared version of libpng and indirectly to libz.
From my Ubuntu 18.04 system (edited to remove unnecessary details):
$ ldd /usr/lib/x86_64-linux-gnu/libXft.so.2 | egrep 'jpeg|png|libz'
libpng16.so.16 => /usr/lib/x86_64-linux-gnu/libpng16.so.16 (0x00..)
libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00..)
One possible solution would be to disable --enable-localpng and --enable-localzlib configure switches and corresponding CMake options if FLTK is configured to use Xft (which is the default). | |

"OK. I can replicate what you report under Ubuntu with test/native-filechooser."

| Giving at least a warning in such a case would be nice. | |

| Fixed in Git repository.
FTR: After recent issues caused by incompatible Xft and image libraries
we decided to prefix the bundled image libs with 'fltk_' to avoid
conflicts. References:
- STR 3347: prefixing embedded jpeg/png/zlib symbols
- STR 3514: Bundled image libs on Linux are incompatible with Xft
- GitHub Issue #232: [fltk 1.4.x/Linux] application invoking native
filechooser crashes under linux if fltk built with --enable-localpng

- Git merge commit: 796a9bf23e63dfc6834b9fd04c10c8c27f894941
@djcj/darealshinji: Thanks for the patches, particularly jpeg-9b.patch.
I used it in a modified form. | |
