X11 problems

[Steve Kirkby]

Beginner here. Perhaps someone, including Paulo Moura, could help with my
problem. Mac G5. OS 10.5.8.

With Nicolas Pelletier's help (for which many thanks) I have got SWI-Prolog
to launch. (That is, swipl runs). I launched the X11 that came with my Mac
and downloaded X11Quartz and ran that (both in my applications/Utilities
folder). At first I managed to create a small data base:

[user].
loves(simon,mary). etc., and ask questions:

loves(X,mary). Also, help(help) worked.

Then, for no reason I could see, I cannot even do that. Entering data into
the database immediately results in an error message about unknown
something. (I cannot reproduce the message for the reason in the next
paragraph).

Now, I can't even get X11 to launch. When double-clicking on the Mac OS X11
I get a message box stating that "X11 failed to load, do I want to
re-launch?" Accepting that repeats the message and even if I dismiss the
massage box it reappears repeatedly at five second intervals and I have to
restart my computer to get rid of it.

In using X11 I tried the following variations:

Mac OS X11 only; Mac X11 + X11Quartz; Mac X11 + X11Quartz + Mac X11 SDK
(suggested by Nicolas); X11Quartz only; X11Quartz + Mac X11 SDK; Mac X11 +
Mac X11 SDK.

I have also tried running X11Quartz before running Mac OS X11 and after.

When I first ran X11Quartz the icon for Mac OS X11 changed to include an
orange circle and there was no sign of X11Quartz. In all later attempts the
circle has not appeared but X11Quartz has, and I have run that as well.

If I do help(help). I get text surrounded with asterisks telling me that X11
has not been run, followed by lots of error messages.

I conclude from this that X11 is not running, or not running properly.

Can anyone advise on what the problem is and how to cure it? Please note
that although I have programmed in BASIC for many years I am totally
unfamiliar with Terminal, and indeed terrified by it because it is so
unforgiving.

Thanks for any help.

Steve Kirkby.

Maybe you modified you account settings to launch X11 at login? If
that is the case, it is started every time you login, and there is no
need to launch it with the X11 icon. Long shot, though...

Xquartz installs its X11 server under the name X11, too. You will not
get a separate icon.

Could you show us the exact error messages?

I put X11 in my Startup Items at first but did not alter any of that area of
my computer. Since that time I manually launched it each session by
double-clicking on it in my applications/Utilities folder.

I can't see the error message anymore because X11 will not load. Instead it
immediately produces the error box "The application X11.bin quit
unexpectedly. Click relaunch etc." The error box returns repeatedly unless I
restart my computer.

I have now found the following error message from a written record that I
had kept, which occurred after I had got X11 to run temporarily, and got
SWI-Prolog to accept a simple database and queries on it:

Well, the message rather says that X11 is not running properly. Did
you ask the Xquartz developers for help in diagnosing/fixing the
problem?

Hello,

I have the following problem when installing swi-prolog 5.8.0 on a mac intel :

the  installation works fine and swi launch  but manpce. gives an error as libraries are not found  in /opt/local/lib. 

I installed the latest version of Xquartz X11-2.4.0.dmg and reinstalled swipl 5.8.0

and the same problem happens : the librairies expected by swipl to be found in

/opt/local/lib

are (on my system) located in

/usr/X11/lib

I tried to copy the first of them 

 /usr/X11/lib/libXpm.4.dylib

in 

/opt/local/lib

and this seems to work as the first error concerns now libXinerama :

ERROR: /opt/local/lib/swipl-5.8.0/xpce/prolog/boot/pce_principal.pl:97:

'$open_shared_object'/3: dlopen(/opt/local/lib/swipl-5.8.0/xpce/lib/i386-darwin9.8.0/pl2xpce.dylib, 1): Library not loaded: /opt/local/lib/libXinerama.1.dylib

Any suggestion ?

Thanks in advance

Could you try the SWI-Prolog 5.9.1 installer and report back if the  
problem persists? The installers are built such that /usr/lib is  
searched before /opt/local/lib so this is not an expected problem.

Cheers,

Paulo

both running leopard) and on the macbook pro :

Hello Paulo,
i tried a workaround both on swipl-5.9.1 and on swipl-5.8.0
and made some progress on the  "X11 librairies not found" problem :

I have added manually the /usr/X11/lib path by running :
---
bash-3.2$ export DYLD_LIBRARY_PATH=/usr/X11/lib
---
and now the first error encountered with "manpce." is no more a matter  
of not finding libraries, but an incompatibiility problem : (same in  
5.8.0)


---------------
ERROR: /opt/local/lib/swipl-5.9.1/xpce/prolog/boot/pce_principal.pl:96:
        '$open_shared_object'/3: dlopen(/opt/local/lib/swipl-5.9.1/xpce/lib/
i386-darwin9.8.0/pl2xpce.dylib, 1): Library not loaded: /opt/local/lib/
libX11.6.dylib
   Referenced from: /opt/local/lib/swipl-5.9.1/xpce/lib/i386-
darwin9.8.0/pl2xpce.dylib
   Reason: Incompatible library version: pl2xpce.dylib requires  
version 10.0.0 or later, but libX11.6.dylib provides version 9.0.0

----------

I also tried not setting DYLD_LIBRARY_PATH but rather :
--
bash-3.2$ export DYLD_FALLBACK_LIBRARY_PATH=/usr/X11/lib
---
which is may be a better choice ( libraries are searched there only  
whenever they were not found)

with the same result mentionned aboved

---------------------

as recommended I use the last Xquartz package  X11-2.4.0

do anybody succeded in installing swipl-5.8.0 on a mac running leopard ?


best regards

Correct. See below.

Looking at the history of the MacPorts portfiles used for building SWI-
Prolog installers it seems that a MacPorts maintainer decided to  
commit changes that have undone the previous work by me and Jan to  
make SWI-Prolog use the libraries in /usr/X11/lib. Those changes have  
gone unnoticed until now. Apparently, the changes are made in order to  
build SWI-Prolog against the "xorg-libs" port, which is a workable  
solution when using MacPorts for installing SWI-Prolog from sources  
but is overkill when using MacPorts for building a SWI-Prolog binary  
installer (as it would lead to include the X11 binaries along with the  
SWI-Prolog binaries, exploding the size of the installer). The  
solution is to defined two variants in the SWI-Prolog portfiles, one  
for installing from sources (which would be the default one) and one  
for building binary installers. I will try to find some time to define  
these variants and rebuilt the installers this week. Thanks for your  
help in diagnosing this problem.

Cheers,

Paulo

Hello,
thanks Paulo,
so there is some hope ;-)
However in a companion e-mail on the mailing list I discuss a  
workaround :

> bash-3.2$ export DYLD_LIBRARY_PATH=/usr/X11/lib
that results in an incompatibility error

> ---------------

so I am afraid that repairing the path is not enough ....
best regards,
