First build of a module

Development

I want to make a module and the compilation stop at the beginning of the file compilation when asterisk.h is included.
It seems I forgot to install something to have this simple error but I don’t find what on the net !
My OS is a Ubuntu 22 and Asterisk 20.6
Here’s the error
gcc -Wall -g -I…/…/…/…/usr/src/asterisk-20.6.0/include -I…/…/…/…/usr/src/asterisk-20.6.0/include/asterisk -I/home/crebouw/projet/lib_noise_filter/ -I…/…/…/…/usr/include -I…/…/…/…/usr/include/arpa -c /home/crebouw/projet/lib_noise_filter/main.c -o obj/Debug/main.o

Thank you anyone for your help

You can achieve this by using conditional compilation directives in your C code. Here’s the code :

`C#ifndef __asterisk_h

// Your module code here
// This code will be compiled only if asterisk.h is not included

#endif`

  1. #ifndef __asterisk_h: This directive checks if asterisk.h hasn’t been included yet.
  2. If the condition is true (asterisk.h is not included), the code within the block will be compiled. This is where you can place your module code.
  3. #endif: This marks the end of the conditional compilation block.

This way, your code compilation will stop at the beginning if asterisk.h is included. i hope it will solve your some problem.

Thank you Danish for your help.
In fact to solve the problem the software only has one line
#include “asterisk.h”
And the compilation has a problem in the call to asterisk.h!

Best regards
