in the directory of /var/log , i see some directory like apache2 , apt , gdm , i wonder does all these folders was made under the syslogd ? i mean do these utilities use syslogd to log their messages or they use their own systems , for example apache use syslog or use its own library?

I am running a syslogd on my ubuntu 10.10 system. I have a apache2 server on the same machine. I have configured my apache2.conf file to send the error logs to the local syslog server.
The config is as under :-
LogLevel notice
ErrorLog syslog:local1
I have also configured the /etc/syslog.conf as under :-
local1.info /var/log/apache2/error_logs
I have created a file in the /var/log/apache2 dir with the ownerships and permissions as under:-
-rwxrwxrwx 1 syslog adm 77 2011-08-11 18:14 /var/log/apache2/error_logs
Next I restarted the sysklogd and apache2 servers with a service command as under:-
sudo service sysklogd restart
sudo service apache2 restart
I thereafter observed the /var/log/apache2/error_logs file and found the entries for apache2 closing down and coming up as under:-
Aug 11 18:14:14 cc apache2[4940]: [notice] caught SIGTERM, shutting down
Aug 11 18:14:19 cc apache2[5282]: [notice] ModSecurity for Apache/2.5.12 [URL] configured.
Aug 11 18:14:19 cc apache2[5282]: [notice] Original server signature: Apache/2.2.16 (Ubuntu) mod_ssl/2.2.16 OpenSSL/0.9.8o

Now the problem is I donot get any other messages thereafter. So it is hardly useful. How can I increase the logged messages from apache. I tried the facility:
local1.*
Then restarted the sysklogd and apache2, but the contents of the /var/log/error_logs file remained similar. Next, I followed the link. I created the perl script for recording access logs of apache2. I then restarted the apache2 and sysklogd. when I opened my website from a browser, the access log did not work. I think I am getting something wrong with the facility value , in apache2.conf it is ErrorLog syslog:local1 ! but the script is suggesting that it should be local2 in the line 4
openlog('apache','cons','pid','local2');
I therefore changed the script to local1 in above line. But still no access log?
For remote syslog logging of the general log files, I set:

I'm reading about shared, static, and dynamic libraries. What is SDL? Is it static, shared, or dynamic?
I always thought a library would be a lot of .h and .cpp files compiled separately into .o files and then if you compiled your own program you could use the -l parameter to link the library and it was all compiled together. Now I'm not so sure.
I don't even see any SDL .cpp files in my system anywhere. All I have are lots of SDL .h files in /usr/include/SDL and I don't really understand the code in them.
I'm making a wild guess here: SDL is a shared library. SDL itself is NOT compiled into my program, therefore SDL must be on any system my program tries to run on. When I compile and link SDL all it needs is the header files to know what SDL function and objects it can use. And then on every system it uses an already compiled SDL shared library thingy somewhere.
So... where is that part of SDL? All I can find are header files.
I'm thinking the advantage of shared libraries is that someone could say update SDL on their own system and take advantage of the new features without having to download new executables with the new version of SDL compiled into them for every program that uses SDL.
So if I'm making an editor and a game engine and they both use a lot of the same .cpp and .h files that I wrote and I'm tired of updating one and then the other and I need to turn them into a library, then a shared library might be kind of a silly solution. I could just make a static library. Right? Because it's not SDL. Nobody else is ever going to use this library.
How can we convert a dynamic library (filename.so) to a static library (filename.a) using gnu gcc . Can we get a static library form a dynamic library . I saw a few post in which the conversion form a static library to a dynamic library is mentioned but, unfortunately, not the other way.

I built it using C++ and wxWidgets so it would be multi-platform. I'm able to compile it and run it in both Windows and Ubuntu using g++. In windows, I was able to distribute it by putting a *.dll file in the same folder as the executable. However in Linux, I don't understand what I need to do so that it would run on any installation of Ubuntu out of the "box". When I build it and try to run it in a different installation of Ubuntu (which has g++) it gives me an error saying that a particular library file was not found and Getlibs fails to find that library file.

For instance, stdio.h includes the following line:

is there a way to debug my library files from DDD? Basically a way to pass the paths to DDD so I can view the source etc. I'm having a segmentation nightmare, which only crops up about every 10 or so starts, I know it's in one file in a library. I could move the source file into my general code to debug, but am sure there's a way in DDD.
