[Brl.Platform] "sys/sysctl.h" not found (on Ubuntu 22.04 LTS)

[GWRon]

William reported via discord:

/home/william/Desktop/BlitzMax/mod/brl.mod/platform.mod/glue.c:24:10: fatal error: sys/sysctl.h: No such file or directory
24 | #include <sys/sysctl.h>

and they raised an Q on stackoverflow:
https://askubuntu.com/questions/1457175/fatal-error-sys-sysctl-h-no-such-file-or-directory-compilation-error-why-this

Now ... they is using Ubuntu 22.04 lts -- so I would goess not "mac os".

The blamed LOC is:

#ifdef __APPLE__
#include <sys/sysctl.h>
#endif

PS: I cannot replicate that issue - simply installed Ubuntu 22.04 LTS in a VM and there it works flawless. They claimed to have done the very same on real hardware (... using the commands I gave and my "fetch ng"-script - as I did).

Another use mentioned the very same thing now - on a Linux Mint 21.1

I am running 21.1 too,

A test code:

Framework Brl.StandardIO
?MacOS
print "I am on a Mac"
?not MacOS
print "I am NOT on a Mac"
?

printed "I am NOT on a Mac" for the second user (no feedback by the first - as he installed Ubuntu 18 meanwhile, where it works as it should).

I let user 2 also try out this code:

SuperStrict
Framework Brl.StandardIO


'!#ifdef __APPLE__
'!  fprintf(stdout,"apple\n"); fflush(stdout);
'!#endif

'!#ifdef __linux
'!  fprintf(stdout,"linux\n"); fflush(stdout);
'!#endif


Print "done"

which spit out (correctly):

linux
done

User 2 mentioned they had simply clicked "Build Modules" in MaxIDE.

When we asked him to compile the module solely via ./bin/bmk makemods -a -h brl.platform this command successfully built the module.

Can some of the modules (built "before") define __APPLE__ somehow?

also interesting are wrong highlighted lines in MaxIDE (here: bah.mod/magick.mod is not yet aware of the image.png-instead-of-brl.pngloader updated)

Does MaxIDE still need Build Modules or is this a hangover from vanilla? Using it implies you have all dependencies for all third party modules installed even if you never use them (database.mod for example).
