This library provides the required class and framework to create
threaded servers in C++. This library is part of a bigger project IT/m,
but you can use it as a framework for new developements.
This library is release under the GNU Library license, and it is an
intellectual property of me, Juan M. Casillas.
This library has been developed using a g++ 2.95.2 version. Also, It has
been tested in a 2.95.3 version, and it works. My libc library version is
2.1.3. The distribution is a Debian potato 2.2. Finally, my arch is a
intel 686 processor, with a 2.2.17 kernel.
You need at least the 2.95.2 g++ compiler, a gnu makefile and the linux threads
installed. If you plan to mess up with the tcpssl class, you need also a
working openssl environment, with all the include and library files
propertly installed. For install and setup openssl, see the openssl
web site. The version of openssl used for test
and developement is 0.9.5a.
The developement platform is a linux (intel) box, so if you plan to migrate
this library to other platform, please send me the patches to include them
in the main developement tree.
This library depends on libtool (at least version 0.85) so you need to have
it installed in your system. You can download it
from the web site Also, you can find the setup and
installation instructions there.
This library also depends on libnetcomm (at least version 0.94) so you need
to have it installed in your system. You can download it
from the web site. Also, you can find the setup and
installation instructions there.
The first thing is uncompress the distribution in a directory. For example,
I will use the /tmp directory:
halt% tar xfz libthreadedserver-0_45.tar.gz
halt% cd libthreadedserver-0_45
halt% pwd
/tmp/libthreadedserver-0_45
halt%
Ok, remember this directory, because we need it in the following step.
We have to plan where to install the library. For developement pourpouses,
is better having this libraries separated from the 'production' ones, so
I usually create a directory in my home, called 'devel'. The only drawback
of this configuration, is that you need to setup the LD_LIBRARY_PATH
environment variable propertly to handle this directory. If you don't
want to set this variable, you can insert the directory in the
/etc/ld.so.conf file and issue a 'ldconfig' command.
In this example, I choose as install directory /home/assman/devel. So I
create it first:
halt% mkdir -p /home/assman/devel/{include,lib}
Now we go to the libthreadedserver directory and edit the Makefile file. In the example,
the libthreadedserver directory is /tmp/libthreadedserver_0_45 so:
halt% cd /tmp/libthreadedserver_0_45
halt% vi Makefile
First, we find the first variable in the file, BASEDIR and set up to the
libthreadedserver directory:
export BASEDIR=/tmp/libthreadedserver_0_45
Second, we find the second variable, INSTALLDIR, and set up to the installation
directory:
INSTALLDIR=/home/assman/devel
Third, we need to point to the libtool & libnetcomm header files, so find the variable
LIBTOOL_INCLUDE and point it to this place. In this example, I assume that
libtool is installed under /home/assman/devel/include, so I setup this
variable in the Makefile:
export LIBTOOL_INCLUDE = /home/assman/devel/include
Four, if we have installed the TCPSSL support in libnetcomm (see library's
documentation files to see how to do that) we can choose if we want to
compile into the library elements the support for TCPSSL code. By default,
this feature is disable, but if you want it, you only have to uncomment the
following line:
export LIBNETCOMM_DEFINE= -D__LIBNETCOMM_USE_SSL__
Now issue a 'make' command to compile all the elements of the library, and to
build it. If no problem is found, you can install the library in the choosed
directory. Note that you need to have write permissions in this directory,
so you should become root if you want to install it in a system directory
(e.g. /usr/local). Now, issue a 'make install'. This will copy and create
all the links and required files.
If you plan to use the library for developement, you need to include the
header files in your programs, and link with the library to proper work
Also, you need to setup the LD_LIBRARY_PATH if you want to run the
programs you compile. In our example, a setup for the LD_LIBRARY_PATH
can be:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/assman/devel
This library has been in-deep tested, but some bugs can arised. Also, you
can have some ideas, or improvements for this library. Please send me
an email if you found some bug, if you need support installing this
library, of if you port this library to a different platform. Thanks for
your help.
