Robert, do you have development packages installed: GCC and such? 
It's way easier to compile from source in your situation
I would actually use my Builder build system for Syllable to compile 
this PERL on Linux. However, you would have to install Ruby. Don't 
know if that's easily available for RH 7.2

I got following under my Fedora Core 1 Linux, when trying to run 
cgi, with rebpro (when run only in -c mode, I got only REBOL - Security 
violation). Am  I able to call librarie under CGI?

[[root-:-linux] jablunkovsko.cz]# ./index.cgi
REBOL - Security Violation
./index.cgi jablunkovsko.cz]#
** User Error: SQLite near "100": syntax error
** Near: make error! reform ["SQLite" error]
ah, I got syntax error in my sql statement, sorry. Now CGI runs in 
linux console by pressing enter in midnight commander, but not from 
the browser :-)

The browser can only run CGI scripts through a web server, not directly.

you can't call it CGI if you run it from the console can you?
BrianH

[703]
Yeah, I was a little surprised that such a script could run at all 
from the console.
Pekr

[704x2]
I can, if it has 755 permission ...
well, I run it from Midnight Commander, maybe it is why I can run 
it .... I just press enter on script. In fact, that is how I verify, 
if the script works at all in CGI mode ...
BrianH

I suspect that the environment variables and input are not filled 
when you run it directly.
Pekr

ah, yes, of course, I just use it for basic check that permissions 
are ok, that my path to interpreter is ok, simply that cgi mode works 
....
now I looked at Apache log - premature end of script headers .... 
hmm, now if I would remember what it means :-) I already met with 
such an error (permission or hidden chars caused by Win-Lin script 
traversal ...)
hmm, I start to think, that if having Linux server (although it runs 
for 2 years or more without the assistance), is good for me. I simply 
have to struggle with getting into it every time I need to config 
something and maybe it is upon my skills :-( .... for occassional 
things, maybe I would better go with plain Windows XP profi plus 
some free Sendmail, FTP server and Apache ....

Have you done the line ending conversion?
Pekr
1-Aug-2006
[711x3]
no ... but I face some strange problems. I put print "Content-type: 
text/html" print newline at the beginning of the script and now it 
does not run even under console, it just says "REBOL - security violation"
ah, it is because I removed -s, sqlite wants to write to log ...
can I lower permission just for that one log file?
BrianH
1-Aug-2006
[714]
Use -s, and then restrict your security to what you should be able 
to do first thing.

now I get following in browser:


** Access Error: Cannot open /home/web/jablunkovsko.cz/sqlite.log 
** Where: connect ** Near: write/append/lines join log-path %sqlite.log 
reform
simply put, sqlite driver wants to write to log, but it does not 
have enough permission to do so?
Volker

[717]
Sounds like that. Or the path is invalid. Does the script run as 
another user, and/or run as chroot?
Pekr
1-Aug-2006
[718x3]
dunno, well, Apache is configured so it runs as particular user ...
when I run script from console, it of course runs, as I am root, 
and then sqlite.log is of root owner ....
maybe I need to configure apache, so it would allow to write files 
in directory other than cgi-bin, dunno ....
Volker

can you make a folder where everyone can write, and create a file 
from cgi? that should show which user.
Or maybe going windows is the better idea?
Pekr
1-Aug-2006
[723x2]
there is no option going Windows currently, I would have to redo 
all my server, I run several domains there etc. I just pray the server 
does not have hd crash one day :-)
what would be rebol code for lowering security for particular file?

secure[path-to-directory allow]
But i guess the error-message would be "security", not "cant write".
(the path-to-directory must be copypasted, vars do not work)

I give up, I will edit sqlite driver and disable loging at all ....
it does not respect log?: false, so what to do about it .... I can't 
expect ppl using it for cgi as having other permissins than usual. 
And if it can't be fixed by setting variable, or by some secure [%sqlite.log 
allow] or something like that code, then it is not suitable for cgi
Volker

if you run with -cs, it has no security anyway. then its some permission- 
or path-problem.
Pekr
1-Aug-2006
[733x2]
yes, I run it with -cs, or it gives REBOL - security violation message 
....
I am going for cgi-based template system, and I expect to use index.cgi 
in my doc-root directory ....
Volker

[735]
can you write something in /tmp? there everyone can write usually.
Pekr
1-Aug-2006
[736]
well, yes, I will probably fix ti by redirecting logging, it is just 
that I would like the sqlite driver to work in such cases, as sqlite 
is cool, handy, and I will have to adapt the source with each release. 
So I would expect setting log?: false to take care of disabling logging 
;-)
Volker

[737]
i understand. but i never looked in sqlite :)
Pekr
1-Aug-2006
[738]
well, it is really handy ... it is SQL, that is importand ... and 
it is completly portable - imagine having small apps, you just need 
cgi-bin site and you can have your rebol app wherever .... no need 
for admin to configure mysql for you, etc., I like it. For small 
to middle stuff it is pretty ok ...
Volker

i would set log-path to %/tmp/, make sure /tmp/sqlite.log does not 
exist  and give it a last try.
actually i rarelly looked in any sql, as for my simple uses files 
are enough.
else i would look in sqlite, because the people here like it :)
Pekr
1-Aug-2006
[742]
yes, of course, no problems. I really liked RebDB - imo really cool 
piece of code ... but unless you need join multiple tables and have 
some more relations ....
Volker

[743]
or need locking or.., like you, then yes :)

ok, going to sleep, 1:45 am here :-) Commented logging on few places 
in driver ...
