Sorry about that. For some reason incorrectly assumed harbour used
automake/autoconf. My bad.

Your initial mail said

A note to everyone else that chimed in, this says <sys/sysctl.h>, *not*
<linux/sysctl.h>. The former was removed from glibc in 2.32. If you
have an older glibc, like on Chimaera, you should still have it.

I suggested installing dietlibc-dev which still provides this file, even
in Daedalus. After you installed it, the above error changed to

gcc -L../../../../../lib/linux/gcc -L/usr/X11R6/lib64 -L/usr/X11R6/lib -o../../../../../bin/linux/gcc/hbmk2 hbmk2.o -lhbextern -lhbdebug -lhbvmmt -lhbrtl -lhblang -lhbcpage -lgtcgi -lgtpca -lgtstd -lgtcrs -lgtsln -lgtxwc -lgttrm -lhbnulrdd -lhbrtl -lhbvmmt -lhbmacro -lhbcplr -lhbpp -lhbcommon -lhbpcre -lncurses -lslang -lX11 -lgpm -lz -lrt -ldl -lpthread -lm
/usr/bin/ld: ../../../../../lib/linux/gcc/libhbrtl.a(arc4.o): in function `arc4_stir':
arc4.c:(.text+0x470): undefined reference to `sysctl'
collect2: error: ld returned 1 exit status

This means that the compiler found <sys/sysctl.h> but could not find the
library that provides the sysctl() implementation. That library is part
of the dietlibc-dev package. Getting the compiler to find the library
would involve adding a -L option with a path to the directory holding
the library and a -l with the library file's name, minus the `lib`
prefix and file extension. You could copy the above gcc line and edit
it to do so or look into the Makefile that sets it up.

However, looking at the list of files that the package includes I cannot
tell which of the many libraries, the lib*.a, files. Also, it might not
play nice with the default libc linkage. On top of that, reading the
package description I now think trying to use dietlibc-dev is a good
idea.

Sorry to have sent you down a dead-end but I think your best bet is to
build this on Chimaera (or earlier).

Hope this helps,
