Hi P.O.,
just a few thoughts (am about to leave the office):
* the compiler needs to be able to resolve the include files, cf.
<https://www.rapidtables.com/code/linux/gcc/gcc-i.html>, on Linux they are
found (while ooRexx
is installed),
* the compiler needs to be able to locate the dylibs (librexx.dylib and
librexxapi.dylib), usually
one could use "-L...path..." to point to the ooRexx library directory, cf.
<https://www.rapidtables.com/code/linux/gcc/gcc-l.html>
So, if the compiler does not find the include and dylib files in the
directories it looks for, you
would have to supply the locations either with supplying the directories with
the appropriate
switches in the appropriate gcc switches or via the environment variables the
compiler may consult.
Good luck! :)
