The same configure +file now works for THINK C 6.0 and MPW 3.2. It is essential that +'MPW' is defined when compiling with MPW; for both compilers, +'HAVE_CONFIG_H' should also be defined. For MPW, the buildall script +takes care of this. + +I moved some files around or renamed them and modified the Makefiles +accordingly. All Mac specific files are now in the Mac subdirectory, +especially config.c, config.h, macmodule.c, and (new) macmain.c. + +I wouldn't bother with the Grammar subdirectory or the Parser generator +(Pgen) -- the needed Pgen output files are part of the distribution. + +If the buildall script stops at a compilation error you are usually +left in one of the subordinate directories. + +Instead of using the buildall script you can also once execute the Set +and Export commands listed at its top (which set compiler and linker +options) and in each of the directories Mac, Parser, Python, Objects, +Modules and finally the python rot directory, execute the two command + + make >makefile.out + makefile.out + +Or you could execute + + make + +have a look at its output and execute selected commands from it. + +The buildall script executes + + Directory {Python} + +which normally prints the current directory, because {Python} +is not defined. If it is set to the python root directory, +you could place buildall somewhere in your command search path and +execute it from anywhere. + +If you are mixing THINK C and MPW, you may experience weird errors +in correct modules. These disappear when you throw away the +module's .pyc file. The errors usually have to do with string +literals containing '\n' or '\r'. The reason is an incompatibility +between their handling of '\n' and '\r' -- in MPW C, '\n' actually is +ASCII CR while '\r' is ASCII LF, which is the reverse situation from +any other ASCII based C implementation. This behaviour is inherited +by Python compiled with MPW C. This is normally not a problem, +but *binary* files written by one system will be mis-interpreted +by the other, and this is what happens to the .pyc files. There is no +easy way to fix this in the source. (This is a real shame, since the +format of .pyc files was carefully designed to be independent of +byte order and integer size -- deviations in the ASCII character codes +were never anticipated.) |
