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.
