I'm still learning how linux works too... :-)

If you cd to the directory:

/lib/x86_64-linux-gnu or /usr/lib/x86_64-linux-gnu/

Can you list libX11 files?  ls -l libX11*

On my Ubuntu machine I see:

-rw-r--r-- 1 root root 2209016 Oct  2 15:13 libX11.a
lrwxrwxrwx 1 root root      15 Oct  2 15:13 libX11.so -> libX11.so.6.4.0
lrwxrwxrwx 1 root root      15 Oct  2 15:13 libX11.so.6 -> libX11.so.6.4.0
-rw-r--r-- 1 root root 1306280 Oct  2 15:13 libX11.so.6.4.0
lrwxrwxrwx 1 root root      19 Oct  2 15:13 libX11-xcb.so.1 -> 
libX11-xcb.so.1.0.0
-rw-r--r-- 1 root root   14048 Oct  2 15:13 libX11-xcb.so.1.0.0

If you don't see these, maybe your libx11 files are located somewhere 
else? If you can find that location, you can add a link time flag to 
point to it.

Aside: In official versions of POV-Ray there is a file in the unix 
directory with more information on the packages to install, but it's out 
of date and I've never gotten around to updating it. So, the yuqk 
tarball doesn't ship with it. Maybe I should bump up the priority there. 


FWIW, it should be you can configure with '--without-x' and get a text 
only version of the 'povray' executable which the yuqk script wraps. It 
will then have no preview display as the Simple Direct Media 'sdl' 
options (like the x11 preview display) also need x11 to work... 'make 
check' should run - and if so, you would be able to render to output 
image files.

Yes, exactly the same thing

I'm going to check the unix distribution to see if there's any
additional information.

I'll take a look at it too...

strange that the linker does not "see" the X11 libraries.  the linker works off
a set of cached directories, if you still have the same problem, have a look at
'/etc/ld.so.conf' and the files in '/etc/ld.so.conf.d/', are your library paths
listed ?  (if yes, the cache may need refreshing ( run 'ldconfig')).

also, wondering what (exact) arguments were given to './configure'.

everything looks good for '/etc/ld.so.conf' and the files in
'/etc/ld.so.conf.d/'. Library paths are present.


> also, wondering what (exact) arguments were given to './configure'.

in accordance with 'INSTALL.txt' doc :

./configure -q COMPILED_BY="name" CXXFLAGS="-O2" --prefix=/tmp/yuqk_427af17e


no strange argument.

finally, rebuilding the cache with ldconfig solved the problem.
(I should have used -v to track what was going on).


so :
running ldconfig, then ./configure, then make, then after a long long
list of messages : no error :)

last messages on terminal :




cat ./povray.ini.in | sed
"s,__POVLIBDIR__,/tmp/yuqk_427af17e/share/povray-3.8,g" > ./povray.ini







As everything is ok, i run make check
I can see the rendering of an image which also closes when finished.
I don't know where it's saved (or not).

Then run make install.
No error :)



I think all these problems come from the fact that I made a
'./configure' and 'make' with the missing X11 library. Necessary links
and cache to the right shared libraries have become corrupted.



**THANKS** for all Jr.

you wrote you're "new to Linux".  recommend getting to know 'script(1)'.  for
instance when you render a scene, you can "record" all terminal i/o, eg:
  $ script -c 'povray myscene.pov' log-file
and you have a full "transcript" in the 'log-file'.

hum... hum...

Big differences between nntp and http.
I made screenshots of both interfaces:
