module programming - step 2

compile your bot with debug: 'make debug' and use gdb to see where it failed ('gdb eggdrop core').

module programming - step 2

Look in module.h for dprintf, copy the line, and do the same thing I did with putlog, in your module after you include module.h.

Now I have a problem with the nmalloc and nfree macros. What should I to to be usable in C++? The problem is the same as with putlog and dprintf.

Are you sure get_user_by_nick is crashing? It returns NULL if the nick doesn't match any user. Use putlog() to figure out exactly where it is crashing. You can even add putlogs into userrec.c. This will help a lot in debugging.

user entry

2003-03-15T12:40:32-04:00

Well, i've been looking deep in module.h, and I did realy found some usefull funcions.
However i havent found how do I get a user entry (struct userrec *) by a string containig the nick, or how to get the handle by the nick like in TCL (nick2hand).
i've found function get_user_by_nick(char *nick); in userrec.c but this one is not working, i always get a segment violation.

why do i need this? Well im working with a H_raw, i need to check the flags of the user and i only now his nick (in a string). Am I thinking well? Is there another way to do this?

greetings
pedro

Re: module loading

2003-03-09T12:10:21-04:00

Another problem: when compiling the file with .c extension the module loads fine but compiled with .cpp it sais:
base: Error loading module: base.so: undefined symbol: base_start__Fv

The module's name is "base"

I solved thisone. I put the base_start function's declaration in extern "C" {}

The previous problem is still unsolved:)

Ok, I did the same thing with dprintf. Is there a global way to do this for all functions?

2. Right after you include module.h, try these lines:

#undef putlog
#define putlog ((int(*)(...))global[197])

That solved the problem, but i get the same error with dprintf. Is this a global problem with functions having "..." in the parameter list?

I'm using now gcc but i renamed the file to .cpp

In module.h, putlog isn't defined with EGG_VARARGS_DEF.

#define putlog (global[197])

Try one of these:

1. Change putlog in your program to (*putlog)

2. Right after you include module.h, try these lines:

#undef putlog
#define putlog ((int(*)(...))global[197])

It should work fine but I dont understand why the EGG_VARARGS_DEF macro doesnt get expanded or how do you call that

by that I presume you mean C++...

g++ is the compiler, c++ the language. I tried compiling it with gcc but it does not take the file as a c++ one so I used g++ but I got the error above.

Real programmers use C anyway

hehe... either you use c++ or assembler *g*

I've never tried it .. I know gcc does c++ if you just change the extension of the file to .cpp but I also know this does affect a number of things.

My question is this, does it compile as C - if it does, then you have your answer. Dont use C++.

module and c++

2003-03-05T17:52:23-04:00

Is it possible to use some classes in an eggdrop module? I'm trying to compile the module with g++ but I get "too many arguments" error when using functions like putlog as if EGG_VARARGS_DEF in the function's definition would not be expanded or something.
