Oops, didn't saw that... But that's strange, because they are linked (ln -s) in the dir, like the libmysqlclient.so
I'll try to find why this happens...

Both are not better than the other. They have both their one specific features, and unfortunately, compiling a plugin for linux is harder (for a nood) than in windows, since in windows, I just have to push Ctrl+Alt+B to get my plugin working...

Ok, found the reason : the dir where gcc search the .so files but a strange thing... Here is the ldd :

Code:

root@server:/usr/src/half-life/myplugin # ldd -d maitredede_plugin_i486.so
                libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7fbe000)
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7fbb000)
        ./tier0_i486.so => ./tier0_i486.so (0xb7f8a000)
        libmysqlclient.so.12 => /usr/lib/libmysqlclient.so.12 (0xb7f4d000)
        ./vstdlib_i486.so => ./vstdlib_i486.so (0xb7f39000)
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7e0c000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
        libz.so.1 => /usr/lib/libz.so.1 (0xb7dfb000)
        libcrypt.so.1 => /lib/tls/i686/cmov/libcrypt.so.1 (0xb7dcd000)
        libnsl.so.1 => /lib/tls/i686/cmov/libnsl.so.1 (0xb7db9000)
        tier0_i486.so => not found
undefined symbol: _Z12MathLib_Initfffibbbb      (./maitredede_plugin_i486.so)
undefined symbol: _Z10Bot_RunAllv       (./maitredede_plugin_i486.so)

There is twice the file tier0_i486.so that is found only one time. Grrr...

Any idea please ? May I have forgotten to include one file in my cpp ?

Yes, you forgot to include some header files (.h files) when you compiled. This is not in the .cpp file but in your Makefile. The Makefile are missing the header files containing MathLib_Init and Bot_RunAll I believe.

maitredede · 07-12-2005 , 03:22

yepee, a post ;)

I think so...

I've included the mathlib.cpp in the files to compile (which defines Mathlib_Init), included mathlib.h in my source, and no more undefinied symobl. But still a 'not found' :

Code:

root@server:/usr/src/half-life/maitredede_plugin # ldd -d maitredede_plugin_i486.so
                libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7fa8000)
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7fa5000)
        ./tier0_i486.so => ./tier0_i486.so (0xb7f74000)
        libmysqlclient.so.12 => /usr/lib/libmysqlclient.so.12 (0xb7f37000)
        ./vstdlib_i486.so => ./vstdlib_i486.so (0xb7f23000)
        tier0_i486.so => not found
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7df6000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
        libz.so.1 => /usr/lib/libz.so.1 (0xb7de4000)
        libcrypt.so.1 => /lib/tls/i686/cmov/libcrypt.so.1 (0xb7db7000)
        libnsl.so.1 => /lib/tls/i686/cmov/libnsl.so.1 (0xb7da3000)
        tier0_i486.so => not found

maitredede · 07-12-2005 , 04:32

OK,

Since I have only problems, I have made this :
- clean install of my distrib (Ubuntu hoary)
- installation of all necessary files
from http://developer.valvesoftware.com/w...ng_under_Linux
- installation of SDK, and my cpp files
using http://forums.alliedmods.net/showthread.php?t=36888
- configuration of the makefile from link above...

I try to compile the serveplugin_empty...

The lines I have changed in the makefile :

Code:

CPLUS=g++-3.4
CLINK=gcc-3.4
CPP_LIB=/usr/lib/gcc/i486-linux/3.4.4/libstdc++.a \
        /usr/lib/gcc/i486-linux/3.4.4/libgcc_eh.a \

to reflect my distrib...

First compilation :

Code:

root@vmubuntu:/usr/src/half-life/serverplugin_empty # ldd serverplugin_empty_i486.so
                libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7fb3000)
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7fb0000)
        tier0_i486.so => not found
        vstdlib_i486.so => not found
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7e82000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

I changed this line :

Code:

LDFLAGS=-lm -ldl tier0_i486.so vstdlib_i486.so ./tier0_i486.so ./vstdlib_i486.so

Second compilation :

Code:

root@vmubuntu:/usr/src/half-life/serverplugin_empty # ldd -d serverplugin_empty_i486.so
                libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7fb3000)
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7fb0000)
        tier0_i486.so => not found
        vstdlib_i486.so => not found
        ./tier0_i486.so => ./tier0_i486.so (0xb7f7f000)
        ./vstdlib_i486.so => ./vstdlib_i486.so (0xb7f6b000)
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7e3e000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
        tier0_i486.so => not found
undefined symbol: _Z12MathLib_Initfffibbbb      (./serverplugin_empty_i486.so)
undefined symbol: _Z10Bot_RunAllv       (./serverplugin_empty_i486.so)

What did I do wrong ?[/code]

chrishx3000 · 07-12-2005 , 09:37

I don't think you should edit the line, change it from:

Code:

LDFLAGS=-lm -ldl tier0_i486.so vstdlib_i486.so ./tier0_i486.so ./vstdlib_i486.so

to (what it used to say):

Code:

LDFLAGS=-lm -ldl tier0_i486.so vstdlib_i486.so

Make sure the line (in your Makefile):

Code:

HL2BIN_DIR=../hl2sdk/valve/hl2bin/bin

points to an existing directory which contains the HL2 bin. Easiest way to check is to do:

Code:

cd ../hl2sdk/valve/hl2bin/bin

from the directory where the Makefile is.

Also, could you please post the lines (from your Makefile) between:

Code:

#############################################################################
# Developer configurable items
#############################################################################

and

Code:

# Things below here shouldn't need to be altered

Sorry for being away.

Are you sure the path

Code:

HL2BIN_DIR=/home/hlds/source/bin

exists?

I'm not sure, I'll check...
Is this path needed just for compilation, or always ?

maitredede · 08-02-2005 , 02:58

HAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAA

I'm really so stupid !!!
I MAY HIT MYSELF, AND THROW MYSELF A GRENADE !!!

Just missing :

Code:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:.

I've made a simple script :

Code:

#!/bin/sh
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:.
make clean
make

And it works... At 7:57am, just before going to work...

A plugin_print :

Code:

Loaded plugins:
---------------------
0:      "MaitreDede's Plugin"
---------------------

But anyway, thanks for your help
