finding libpcre.so.3 has to be easier way
 

hi-

# /home/thirdshift/abyssws/htdocs # haxelib install flex
Called from EReg.hx line 31
Uncaught exception - load.c(223) : Failed to load library : /usr/lib/neko/regexp.ndll (libpcre.so.3: cannot open shared object file: No such file or directory)

i have pcre and pcre-devel checked in package mgr as installed.

the .so file is in the pcre package summary of files list

well...there are a zillion pcre downloads to try from
an ftp site. and once i install my pcre and pcre-devel
am i suppose to just start picking from the ftp with
an eductated guess and ./configure make make install
and if it is not right get rid of it from package mgr and move on to the next one. now that would be frustrating!

i am thinking this one but what does the 3 at the end of
pcre-7.3 mean? would that be the one and why?
pcre-7.3.tar.bz2

well i am going to try if it will let me to uninstall the
pcre and pcre-devel and then install the archive and see.

thanks for any tips.

jim

drats.

didnt work. i will report this at the haxe community or mail list.

What does ls tell you about the installed pcre-libs?
Or even a

'libpcre3' seems to be a special Debian construction.
You can download the source here :
http://packages.debian.org/etch/i386/libpcre3
(pcre3_6.7+7.4-3.diff.gz and pcre3_6.7+7.4.orig.tar.gz)
Unpack the ..tar.gz file and the ..diff.gz file to some folder.
Rename folder pcre-7.4 to pcre3-6.7+7.4 and apply the patch with:
'patch -p0 < pcre3_6.7+7.4-3.diff'
Then you can compile and get 'libpcre.so.3
g++ (c++) is needed.
Good luck !

i followed your instructions which were great.
there is a catch though. still get the same msg.
the new .so file it generated when i followed your
steps was libpcre.so.3.12.0

i get this error:
#:~/abyssws/htdocs> haxelib install flex
Called from EReg.hx line 31
Uncaught exception - load.c(223) : Failed to load library : /usr/lib/neko/regexp.ndll (libpcre.so.3: cannot open shared object file: No such file or directory)

i copied the new generated libpcre.so.3.12.0 to
/usr/lib and /usr/local/lib. i thought that would do it.
hmmmm......wonder why??
but that was really cool. i never saw a patch applied
before like that.

i crossposted at haxe.org mail list with your tips to see if that gave them any ideas.

thanks for helping me out.

Usually you'll have a series of symlinks created for
libs, hence my question with the locate above. For
you it might have been as trivial as to
ln -s /usr/lib/libpcre.so.3.12.0 /usr/lib/libpcre.so.3


Not quite sure where knudfl's libpcre3 and debian came from ;}

This official Debian package libpcre3 is quite different from others.
From 'README.Debian
Links are included in the install result, but may be your application
is not looking in /usr/local/lib

Quite possible ... it's just that he nowhere mentioned libpcre3
or debian in this thread, and his profile speaks of SuSE.

Tinkster :
Seems odd, you are right, but nobody else except the Debian people makes the source
for this library. The "patch" is some 16000 lines.

PS: libpcre.so.3 comes from "libpcre3" only, AFAIK.

hi again-

~> $echo $PATH
bash: /opt/kde3/bin:/home/thirdshift/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/X11R6/bin:/usr/games:/usr/lib/jvm/jre/bin:/usr/lib/mit/bin:/usr/lib/mit/sbin:/usr/local/lib:/usr/local/lib: No such file or directory

I typed in man ln in terminal. i will read that topic
again in my suse linux book.

yes. i think i remember links included when it created
the actual library file.

and that ln command is cool. thanks for that example.

haxe.org mailing list remains silent for reasons unknown.

well i did what i could and it is really cool you helped
me out with this. i will keep an eye on the haxe list
for a few days and see if anything comes across.

i have a few alternatives if i cant get haxe with flex to work
like use haxe without flex, use the aptana plug-in for AIR, or never mind flex altogether.

i am going to enjoy sunday and put this aside.

it was very cool to receive the help,

:~> echo $PATH
/opt/kde3/bin:/home/thirdshift/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/X11R6/bin:/usr/games:/usr/lib/jvm/jre/bin:/usr/lib/mit/bin:/usr/lib/mit/sbin:/usr/local/lib:/usr/local/lib

path looks like this. i made a cut and paste error and didnt catch it.

Dynamically linked executables *don't* look for their libs in the
$PATH, but in $LD_LIBRARY_PATH or in /etc/ld.so.cache (which is
populated by ldd with libs from paths that are found in /etc/ld.so.conf).

/usr/X11R6/lib/Xaw3d
/usr/X11R6/lib
/usr/lib/Xaw3d
/usr/i386-suse-linux/lib
/usr/local/lib
/opt/kde3/lib
include /etc/ld.so.conf.d/*.conf

thanks. i didnt know that.
this is what is in my /etc/ld.so.conf

the shared library i generated with the patch is
in /usr/local/lib.

i will think it over a few days and decide
what to do. this new book may be on its way
back to amazon soon in the used section :-)
i might not keep it because i dont know what
other things could go wrong and i dont want to
stick around to find out.

thanks Tink-
later

When you run an
ldd -v | grep libpcre
.... what output do you get?

hi Tink and everyone,

very happy to say that i finally got it installed and working.
i reinstalled but this time instead of using an installer
followed a step by step tutorial on compiling with ocaml
and using cvs.

this is what i was able to do (from the tutorial - a quote)

"Our AS3 based Flex application is creating a new instance of our haXe based HaxeApplication class and calling a method on it, which in turn is creating and returning an instance of a Flex AS3 class. We can now communicate bidirectionally between haXe and Flex/AS3."

i am keeping haxe, neko and geany. the problem must be with me as i
am not a linux expert and doing this proves that it does work.

haxe with flex

the only bad thing is i screwed up my editors for kde.
i was able to get an rpm from a repository either on cd or web
and install a new one. kate, and one version of kwrite are screwed up!

thanks!
jim
