xf4vnc-devel

[Yaroslav H. <li...@on...>]

I wanted to try xf4vnc since it seems to perform better than RealVNC for
GLX graphics in the application of interest in our group.

Unfortunatly there were no source tarball provided for 4.3.0.999 so I
could build it for amd64 architecture.

Is there a way to get a source snapshot of 4.3.0.999? I didn't mention
relevant cvs tags on files I've checked log for.

 I had to get all the sources of modular from CVS. After I've built it,
and installed locally in my account name (I had to adjust few Makefiles
manually to don't have make install attempt to install  under /etc/X11), I've
started it up with


/home/yoh/deb/misc/vnc/modular/bin/bin/Xvnc :6 -desktop X -auth /home/yoh/.Xauthority -geometry 1280x1024 -depth 24 -rfbwait 120000 -rfbauth /home/yoh/.vnc/passwd -rfbport 5906 -fp unix/:7100

Then I got it segfaulted after  authentication step

Program received signal SIGSEGV, Segmentation fault.

Probably it was built with optimization though so it might be trickier to
spot the problem...

Please advise either on how to get a source snapshot of the release or how to
fix current problem ;-)
