Hello. I have a new operating system called PDOS
which works on both PC and mainframe, which
can be found here:
http://pdos.sourceforge.net/
I know nothing about Python, my focus is on C90,
but I wish to run this mainframe assembler, asma,
which was written in Python, not C:
https://github.com/s390guy/SATK
It needs Python 3.3 as a minimum, so I wish to port
that version, first to the PC version of PDOS, then to
the mainframe version.
I don't wish to run configure, I want to hand-construct
the makefile. PDOS is a very simple system, so I only
want to produce a single executable, no DLLs etc. I
don't need extensions to work or anything, all I need
to be able to do is run asma.
I've started constructing a makefile (see below), which
I execute with pdmake, included in PDOS. I only have
a C90 runtime library, no more, no less, so I don't know
whether Python will actually build in my environment,
but so far things have been building successfully.
However I'm currently stuck on this unresolved
external:
python.a(abstract.o)(.text+0x668c):abstract.c: undefined reference to
`PyExc_StopIteration'
What source file is meant to define that variable
(PyExc_StopIteration) as opposed to just declaring
it or using it? I tried looking at the OS/2 EMX for
hints, but wasn't able to figure it out.
Note that I am building a Win32 executable to start
with, but it is linking against my own C90 library
which will call either Microsoft's MSVCRT.DLL on
Windows, or my own MSVCRT.DLL when running
on PDOS/386 (aka PD-Windows).
I also don't know whether Python will survive being
transferred to an EBCDIC environment, as that is
where it will ultimately need to be compiled and
linked (MVS/380), or at least assembled, before it
can wind up on PDOS/3X0. Well, maybe it can all
be done on Windows. I need to see what asma
is capable of.
Thanks. Paul.

Hi,
one thing is not clear to me, do you absolutely need to use "asma"?
