Status Report on the Port of SPITBOL to Apple OSX

We are making progress porting SPITBOL to Apple’s OSX operating system. The needed files can be found in

github osx git repository.

The repository can be downloaded by the command

$ git clone

The makefile has been modified to have 64-bit osx as the default, so to build the system do

$ make

Test spitbol by running various test programs in the subdirectory .text/. For example

$ ./spitbol test/hi.spt

To see if the program runs at all, try

$ ./spitbol

This produces several lines with help information. Note that running spitbol with no arguments just shows the program link is complete and that at least part of the C runtime is working. This does not test any of the translation of the Minimal source code to assembler.

The current status is that the help text can be printed, but even the simplest test yields

Bus error: 10

We will keep you posted.

On a separate front, one user reported problems building 32-bit SPITBOL. The makefile has been updated so that it works using gcc on a 32-bit Linux system.

    the command to clone the repository didn’t work. I used
    git clone
    debug didn’t work with the cloned makefile. a. I think the ASMOPTS definition for debug needs to be
    ASMOPTS = -g -f $(ELF) -d $(TARGET) -d m$(WS)
