Perhaps because you didn't build a multi-threaded application :)

• use -pthread
• use -D_REENTRANT and -lpthread

Another problem could be it didn't find its config file, you didn't specify : -DCHAT_DIR=<folder where it could find its chat_service.cfg>

But I suggest you use our makefiles, because as you can notice, you forgot at least 2 parameters. You have choice for NeL, you can use CMake (preferred) or autotools.

I use -lpthread to compile. And fro from the log, it find the config file.

Here is the log:

kervala,
Can you give me some docs or links to learn how to create a simple server project use CMake?

Thx!!

I don't know if it's related to that, but you should see :

http://stackoverflow.com/questions/875789/gcc-do-i-need-d-reentrant-with-pthreads

With your compilation command, you're building a single threaded application.

-pthread is not -lpthread (notice the l)

I don't understand why you want to create a makefile to compile only chatserver. It's compiled by default with CMake.

ok, I use

• g++ -L/usr/local/lib -lnelmisc -lnelnet -I/usr/local/include/ server.cpp -o server -ldl -lpthread -lxml2 -D_REENTRANT
• g++ -L/usr/local/lib -lnelmisc -lnelnet -I/usr/local/include/ server.cpp -o server -ldl -pthread -lxml2

The result is the same.

I just want to know how to write some test program to learn more about NeL.
So a simple command to compile a simple test program is enough.
And I am a beginner for write a project use the smart tool like CMake, and I didn't find any docs about how to use the NeL library in a new project under linux(except a doc HelloWorld client from [[http://www.opennel.org/confluence/display/NEL/HelloWorld]]).

Thx again!

I don't know why it's crashing, I never used it :(

But if you plan to use NeL, you should begin by "misc" samples, there are easier to understand :)

Currently, there is no FindNeL.cmake module to find NeL include path and libraries to link in Hg.

But you can use scripts from : http://code.google.com/p/object-viewer-qt/source/browse/trunk/

Especially :

• To find NeL : http://code.google.com/p/object-viewer-qt/source/browse/trunk/CMakeModules/FindNeL.cmake
• To compile your program using NeL libs : http://code.google.com/p/object-viewer-qt/source/browse/trunk/CMakeLists.txt
