missing zlib compression library for compression module

levts · Post by **levts** » Mon Sep 29, 2003 2:10 am

Hi all,

i wonder me why there is no compression module
compiled. zlib is installed on my system and
working well (i think). Its an eggdrop1.6.15
on SuSE8.1 with TCL8.4. The Bot is running well.

any suggestions or hints ?

thx in advance
tom

I have exactly the same problem at Debian 2.6.9.

I have installed zlib1g, zlib1g-dev and zlibc, and:

robot:~# locate zlib.h
/usr/include/linux/zlib.h
/usr/include/zlib.h
robot:~#

Configure has exactly the problem reffered above...Any help would be extremely usefull, just to find out what goes wrong!

you don't have zlib installed in default places (compiler/linker default search paths: /usr/include, /usr/lib, /usr/local/include, /usr/local/lib)

solution:

use the environment variable CFLAGS to specify location of header zlib.h: -I/path/to/your/zlib/header

use the environment variable LDFLAGS to specify location of library archive libz.a (or libz.so): -L/path/to/your/zlib/library

(or do a sane zlib install

Errrr....If u see my message, when I locate it, locate founds it at /usr/include. I did the same trick I did with the tcl, edit /etc/ld.so.conf and put there /usr/include, and run "ldconfig" , it still denied to play...I can't imagine what the f*ck is causing that thing....If anyone knows...!

I already explained to you "what the f*ck is causing that thing"

it's not only the header, the library itself is also checked (the configure script tests whether it can compile & link against libz.so using gzopen())

if you are unsure how to use CFLAGS/LDFLAGS to tell the configure script where your stuff is located (this method applies to other misplaced libraries as well), ask again

btw ld.so.conf has nothing to do with /usr/include, it specifies library locations searched by the linker/loader

Thanks a lot for your interest

Yes I would like to ask u how exactly I will use these flags, and tell you that the problem is at make iconfig. It is the script that compress.mod runs, not the general ./configure script.

I would like to mention that the problem DIDN't exist! Something happened meanwhile...I have re-installed zlib1g, zlibc and zlib1g-dev (it is quite easy, Debian rulez

) but the problem STILL exists!

Thanks a lot

yeah I know that the problem is with compress.mod's configure

if your login shell is bash/ksh, issue the following commands:

$ export CFLAGS=-I/path/to/your/zlib/header
$ export LDFLAGS=-L/path/to/your/zlib/library

if your login shell is csh/tcsh:

% setenv CFLAGS -I/path/to/your/zlib/header
% setenv LDFLAGS -L/path/to/your/zlib/library

and then rerun make iconfig

debmond,

Look what happened:

I set the environmentals, and tried "make iconfig". It told me that "New Environmental have been set, please run make distclean and start over"

I did it, then it didn't start over at anyway...told me that there was no rule to "make distclean". What I did?

1)rm -rf eggdrop1.6.17/
2)wget geteggdrop.com ; tar xfz eggdrop1.6.17.tar.gz
3)apt-get install bin86 make patch build-essential
4)./configure
5)make iconfig

Everything went perfectly. I don't know what exactly fix it, but it work

Thanks for your time:)

P.S: I will soon upload a user-friendly manual for users who use Debian...It is quite difficult for newbies to find what goes wrong with eggdrop and the best Linux distro
