How to compile MiNT 0.99 with PureC
-----------------------------------

(1) Special files
First of all, you need a special osbind.h. This is because Pure's own
version differs in some small details from the GCC header files. You
can't use Pure's tos.h, either, because in its latest versions it already
defines some of MiNT's data structures. You can either copy osbind.h into
the MiNT source directory or copy it into your PureC include folder. If
you are using the MiNT library, all should work fine without this file.
This is all what's needed. You can either use the command line versions
of PureC, or you can use the PureC shell (copy mintpure.prj to the source
directory). I am compiling MiNT with GNU make (latest version at
atari.archive.umich.edu should work fine) and a self-made 'cc' command,
that I've specially written for the PureC command line versions (see
makefile.pcc). This tool is still being tested, and I've not yet decided
how to distribute it. If you are interested, write to me.
If you're going to use the PureC shell, you'll have to 'manually'
translate the .spp files to the PASM syntax using asmtrans.ttp. The
syntax is
asmtrans -purec -o outfile.s outfile.spp
genmagic.ttp is needed to create the file magic.i, which in turn is
included by the .spp files.
(2) Things to do
So far, I've made no attempt to translate asmtrans with PureC. Try it
yourself (you'll need alloca; might work with the MiNT library version
for PureC) or compile them with gcc.
(3) Caveats
This is a preliminary 'port'. It seems to work fine on my machine, but
this guarantees nothing:
There's still a conflict in the way PureC saves registers with what MiNT
file system drivers or device drivers expect. You will have to use PureC
1.1 to get the correct behaviour.
