I've tried it in Linux, but it fails to compile:
===> PAK128 factories
./makeobj PAK128 ./pak128/factories.pak factories/
Makeobj version 55.2 for Simutrans 112.4 Nightly and higher
writing file ./pak128/factories.pak
reading file factories/brewery.dat
packing factory.brewery
FATAL ERROR: Factory - Missing an indentification color! (mapcolor)
Aborting program execution ...
I've managed to compile a version of the old pak128.newlandscape with wine, a version of makeobj.exe and a modified pak128.bat and it worked fine, except for the error in pak128.bat I pointed out in the other thread. However, rail bridge entrances seemed to be double height when joining tracks at the same level. I'll check if it goes away if I manage to compile it with the Makefile.
