[SOLVED] Missing vncviewer binary in tigervnc-1.16.0-1

I just updated from tigervnc-1.15.0-3-x86_64 to tigervnc-1.16.0-1-x86_64 and I'm now missing the binary for vncviewer.

Is this expected?

➜  ~ ls /data/tmp/tigervnc/
tigervnc-1.15.0-4-x86_64.pkg  tigervnc-1.15.0-4-x86_64.pkg.tar.zst  tigervnc-1.16.0-1-x86_64.pkg  tigervnc-1.16.0-1-x86_64.pkg.tar.zst
➜  ~ find /data/tmp/tigervnc/ -name vncviewer
/data/tmp/tigervnc/tigervnc-1.15.0-4-x86_64.pkg/usr/bin/vncviewer

I see no mention of removing vncviewer from tigervnc, at least not here: https://github.com/TigerVNC/tigervnc/bl … README.rst

Re: [SOLVED] Missing vncviewer binary in tigervnc-1.16.0-1

It seems to actually be a build problem.
When trying to rebuild the package, I see:

         FLTK NOT found. TigerVNC viewer disabled.

It's probably a issue with fltk1.3 not being found in /usr/lib/fltk1.3, so it gets automatically disabled and built without.

Edit:

That seems strange:

$ fltk-config1.3 --libs
/usr/lib/libfltk.so

$ readlink -f /usr/lib/libfltk.so
/usr/lib/libfltk.so.1.4.4

That seems to be the wrong version (after installing fltk, otherwise the so is not found).
The config script produces the wrong path.
I thougt adding some cmake options would help, but still leads to an error

    -D FLTK_CONFIG_SCRIPT=/usr/bin/fltk-config1.3 -D FLTK_INCLUDE_DIR=/usr/lib/fltk1.3

so it's an error in fltk1.3, libdir in fltk-config-1.3 needs to be

libdir=${exec_prefix}/lib/fltk1.3

See https://gitlab.archlinux.org/archlinux/ … 03e6fd1c3a which removes tigervnc-1.15.0-fltk1.3.patch rather than updating it.

is not needed if the config script is used and outputs the right path to the correct .so version, it's a symptom of the script doing the wrong thing.
Otherwise this works:

I guess actually something in this patch fails to correctly patch the generation of the config script:
https://gitlab.archlinux.org/archlinux/ … type=heads

`fltk-config1.3 --libs` pointing to `/usr/lib/libfltk.so` is for sure wrong, since it doesn't provide that symlink

Re: [SOLVED] Missing vncviewer binary in tigervnc-1.16.0-1

Please open an issue on Arch's gitlab instance against fltk1.3 if you want the config fixed and as issue against tiger-vnc for the missing viewer.
