[mapserver-dev] Debugger for Mapserver

[Mauricio Herrera]

*First thank you for to be too patient Alan!*

Sorry, I had confused,because in the mapfile(.map) exist a DEBUG MODE
(1...5). But ok.
I had done  this --enable-debug when I installed mapserver on my pc..
I followed your tips: I installed GDB and I added a graphical interface
(KDbg and DDD) on my linux distribution. Today, I am debugging the MapServer
executable, thanks a lot!


*I do not want to abuse your kindness but I have two other questions related
to the topic**. *(I think they are very easy  questions for you,but for me
are complicated)

*Question one:*

Do you know if the  files of mapserver(source code) have a function for to
add the mapfile (.map) like  input data?  What do I want?  only read data
values from my (.MAP)  with my GDB
(with the aim of testing). Is it   possible to do ?. Do I need to modify any
file? or I need to configure GDB for to get input data from my
mapfile(.MAP)..

Example ( a function of mapserver):  readmapfile("/usr/local/data.map");
//like default input  test

*Question two:*

If I want to debug mapfile.c for to see its operation in real time with
input data (.MAP) , is it  necessary to load the  mapserv's executable  on
the GDB?

I asked this because I did some test with KDbg and DDD.. And I insert
several breakpoints in the mapfile.c . And never stopped... Only entered in
the next files: cgiutil.c,mapio.c and obviolsly mapserv.c



*
thanks Alan.. I appreciate your help*

*comment for expert developer community

Finally a short comment to the expert developer community (maybe I will send
in a new mail)

Well I think that for new developers like me, would be great that the
website (http://mapserver.org/) have tutorials.

About. Developing source code of Mapserver  with any open source IDE.
I think, there is not enough information in the development section.. Maybe
there are  a lot people like me that they would like to develop on mapserver
and they don't know how to begin..



Thank you again!
