World: r3wp

there is no special reason why nobody would not be able to run pdflatex, 
in principle. there may be security rules in effect though (most 
distribution come with some kind of security extension to the usual 
Unix stuff), I wouldn't be surprised if Apache was being restricted 
to what it can do to avoid default installs being easily vulnerable.

you should search around on the web - I'm sure someone else in the 
world did what you're trying to do as well.

Hi, I have just joined. Is there a way to increase the font size 
on my screen. I can barely read this text?

try clicking the A icon in the icon bar above the text area.

Clicking on the A icon? Ahah! Got it. Thanks Henrik.

I found this at http://www.wikipublisher.org/wiki/Wikipublisher/InstallationExperiences


Well - I�ve just tracked it down. As you predicted in your comments 
on 00098 this is nothing to do with the XSLTPROC errors - it is all 
to do with PDFLATEX. The script was being prevented from doing the 
necessary by SELINUX, which controls access not just by permissions 
(which were sufficiently open) but by running process. A command


chcon -R -h -t httpd_sys_script_rw_t /usr/share/texmf/* has opened 
things up enough to sort it out.

but that doesn't do anything on ubuntu

On the twiki site http://twiki.org/cgi-bin/view/Plugins/GenPDFLatexAddOn

I found this

#  Setup the Latex rendering software


    * Ensure that a latex document preparation system is available to 
    the user name (uid) running the twiki web server.

    * Install any custom latex style files needed. The best suggestion 
    is to create a local texmf tree accessible by the server. For example, 
    for an apache server running as 'nobody' on a linux system:

          o create the directory /home/nobody/texmf/tex/latex, with reasonable 
          permissions.

          o Place the custom .cls and .sty latex files in this directory

          o as user root or nobody, run texhash /home/nobody/texmf to create 
          the ls-R latex database file for the /home/nobody/texmf/ tree.

I documented my installation so can anyone see if I did anything 
wrong?

http://rebol.wik.is/Wikipublisher

What is a pity is that this software uses Apache2, php5, and perl 
scripts to achieve the outcome when potentially it could all be done 
by Rebol.

there might even be some java there too that transforms the wiki 
markup to xml

Fixed my wikipublisher install ... the default config was for mac 
and I had to use the linux one

Does anyone know which linux distros the SDK works on? I had it working 
on Ubuntu 9.10. After upgrading to 10.04 nothing worked. I have installed 
the required libraries, which did the trick on 9.10. Did not work 
on 10.04. I might have to revert to 9.10 just to get my Rebol programmes 
working again.

64 bit?

2.7.6 or 2.7.7 ?

64 bit, Ubuntu 10.04, Kernal 2.6.32-22-generic, Gnome 2.30.0.

presumably the 32bit libraries are loaded ?

LDD ?

this is funny http://cr.yp.to/daemontools/start.html

a perfect example of why I love to hate linux in general.

Qi Ben NanoNote http://sharism.cc/Now we have a need for MIPS Linux 
builds for REBOL :)

Thanks Graham, the 32-bit libraries were not loaded.  This sent me 
on a 24-hour excursion into Ubuntu Linux land where I discovered 
all kinds of things about loading 32-bit libraries into a 64-bit 
operating system that I never thought I needed to know.  After much 
exploration, several trips up and down the Ubuntu Linux technical 
Amazon, I eventually found in a dark, murky backwater the exact technical 
information I needed to complete my journey:


https://bugs.launchpad.net/ubuntu/+source/ia32-libs/+bug/431091?comments=all

On successful completion of the obligatory wget command

cd /tmp

wget http://security.ubuntu.com/ubuntu/pool/universe/i/ia32-libs/ia32-libs_2.7ubuntu6.1_amd64.deb
dpkg-deb -x ia32-libs_2.7ubuntu6.1_amd64.deb ia32-libs
sudo cp ia32-libs/usr/lib32/libstdc++.so.5.0.7 /usr/lib32/
cd /usr/lib32
sudo ln -s libstdc++.so.5.0.7 libstdc++.so.5


And the other commands above, I was delighted to find that rebcmdview 
now works on Ubuntu 10.04 on my laptop.  So, once again, thank you 
Graham for pointing me in the right direction.  I would never have 
figured this out for myself without the 32-bit library information. 
Much appreciated.

You're welcome.

Thanks for posting that caelum!  Do you mind if I repost those instructions 
in the tutorial at http://re-bol.com?

Please do. And thanks for writing that tutorial. One of my great 
Rebol learning experiences. I use it often. I watched all the videos 
too.

I found a second solution and have posted it on my website (so I 
don't lose it.)
http://www.francisayley.org/rebol_on_Ubuntu10.htm

No, the second solution above is for the libstdc++5 libs, not the 
ia32-libs. (I think I need some sleep)

Of note, I think Linux Mint comes with the 32 bit libs preinstalled.

Does anyone know if you can use Rebol/View on linux server for scripting 
with X-windows installed?

if running view in non-gui mode ... does it still need those libraries? 
 Can some dummy library stubs be created?

Reason being that core with ssl has not been released as a free product 
... ( I do have it though as I have the sdk )

rebol/view on linux is certainly usable without an X server running

you'll need to have a bunch of X libraries installed, though

(and you'll probably need to use Xvfb)

btw, didn't find a way to start REBOL view without my error:
** User Error: Bad face in screen pane!
** Near: size-text self


all I can do right now is use rebface, which doesn't do any graphics 
code on init.

even   rebcmdview -vs   fails with the above error.


note that I'm using rebol within a remote ssh with no desktop setup 
(though I have the Xlibs installed IIRC)

As Andreas said... you probably need to run Xvfb.

ok will check that out

Can someone tell me what this means?

Seems something is crashing but I don't know what.

Some process exhausting memory.

Robert, the kernel will kill processes that take too much memory 
to avoid for the whole system to crash

check out that you have enough swap space for the processes you are 
running - this will prevent the kernel killing processes, although, 
if you are swapping a lot the system may get so slow that you get 
a worse situation than what you have now. much better would be to 
have enough RAM to fit everything.

Thanks. I have cross-checked. This is a system running in a xen VM. 
I have raised the memory, and updated the app that caused the problem. 
Not it works.

Hi, need an advice. I am setting up very simple CGI, and I use ClearOS, 
and CZ installation. But one of CGI scripts seems to be in UTF-8 
or so, and I think error I am getting has nothing in common with 
Apache or its config. When I press enter on the file in Midnight 
Commander, I get following error (the text is my english translation, 
no exact wording):


./test.cgi: line 1: #!/usr/local/rebol-sdk-cmd/bin/rebol: not 
a file nor a directory


It seems like file is containing an unicode BOM marker at the very 
beginning, so even shebang line can't be interpreted? How can I solve 
it, apart from converting file into some CZ compatible charset?

Second question - my server is behaving quite strangely - following 
script sometimes works, sometimes it does not. Sometimes ls -l is 
showing me files, sometimes it shows strange output. Is fsck safe 
tool to check filesystem integrity?

Have you checked if the file does start wth a BOM? My str-enc-utils.r 
at rebol.org includes a BOM? function. 


 Apache will process a file with a correct BOM - https://issues.apache.org/bugzilla/show_bug.cgi?id=16687

http://sankuru.biz/en/blog/8-joomla-configuration-issues/46-crushing-the-head-of-the-bom-marker-monster.html

- has a 'grep' line that checks if a file contains the BOM, and a 
bash script that can remove it from all files in a directory.

Untested, as I've not seen this myself before.

Can you give an example of the odd 'ls' output?
