Compiling from Source on Debian 12 Bookworm

[blizzard4591]

Dear Maintainers,

I am trying to compile Homegear on Debian 12 with G++ 12.2.

src/HelperFunctions/Net.h, src/HelperFunctions/Math.h and src/Security/Gcrypt.cpp are missing ´#include ´, since they make use of std::array but do not import it.
This failed compilation with GCC 12.

Furthermore, the include order for sched.h seems wrong, since this happens:

In file included from Settings/Settings.cpp:31:
Settings/Settings.h:252:36: error: 'SCHED_OTHER' was not declared in this scope
  252 |   int32_t _rpcServerThreadPolicy = SCHED_OTHER;
      |                                    ^~~~~~~~~~~
Settings/Settings.h:252:36: note: the macro 'SCHED_OTHER' had not yet been defined
In file included from /usr/include/sched.h:43,
                 from /usr/include/pthread.h:22,
                 from /usr/include/aarch64-linux-gnu/c++/12/bits/gthr-default.h:35,
                 from /usr/include/aarch64-linux-gnu/c++/12/bits/gthr.h:148,
                 from /usr/include/c++/12/ext/atomicity.h:35,
                 from /usr/include/c++/12/bits/shared_ptr_base.h:61,
                 from /usr/include/c++/12/bits/shared_ptr.h:53,
                 from /usr/include/c++/12/memory:77,
                 from Settings/../Database/DatabaseTypes.h:38,
                 from Settings/../Database/IDatabaseController.h:34,
                 from Settings/../BaseLib.h:34,
                 from Settings/Settings.cpp:32:
/usr/include/aarch64-linux-gnu/bits/sched.h:28: note: it was later defined here
   28 | #define SCHED_OTHER             0

This can be solved by switching the include order of BaseLib.h and Settings.h in Settings.cpp.

Since I am not sure of how development is done here, I did not create a pull request. If you point me to the branch you want, I can do that.

I solved the array related issues by adding the include:

#include <array>

The SCHED_OTHER compiler error can also be solved by putting the following additional include into the file:

#include <sched.h>
