# kpy/ -- the Python binding of the Klammermachine.

#
|

|
|
# klammertext.cpp is a CPython extension module (see its header comment).
|
||
|
|
# Like ref/reflect.so and sks/document/document.so it links against
|
||
|
|
# libklammertext.so and shares the engine's class layouts, so it is rebuilt
|
||
|
|
# whenever they are (mac/Makefile's "all" runs "make -C kpy"; com/Makefile's
|
||
|
|
# "redo" and dbg/rebuild.sh clean it -- a clean that misses a directory is a
|
||
|
|
# mixed-object hazard, not a tidiness one).
|
||
|
|
#
|
||
|
|
# The module's filename carries the interpreter's ABI tag
|
||
|
|
# (klammertext.cpython-3XX-<arch>.so) from python3-config, the same tool
|
||
|
|
# makefile.env takes the include and link flags from: the module is bound to
|
||
|
|
# the ONE Python the library was built against, by decision. The library
|
||
|
|
# already links that libpython, so the link line is the commands' link line
|
||
|
|
# with $(SHARED) in place of $(EXPORT_DYNAMIC).
