There are two important points. First, the python executable must be
|
|
linked with the -E option to explicitly export all symbols. This
|
|
works with the vanilla interpreter, but I am not sure how friendly it
|
|
will be when I try to embed the interpreter in a larger application.
|
|
It may be necessary to hand tune the exports using the -e option.
|
|
Anyway, the additional flag to $(CC) is "-Wl,-E", which passes the -E
|
|
flag to the compiler. My link line (from an actual run) looks like
|
|
this:
|
|
|
|
cc config.o -Wl,-E libModules.a ../Python/libPython.a ../Objects/libObjects.a ../Parser/libParser.a -lm -ldld -o python
|
|
|
|
[Guido's note: as of Python 1.5, replace the four libraries with
|
|
../libpython$(VERSION).a]
|
|
|
|
Second, the dynamic module must be compiled with the +z option to make
|
|
it position independent and then linked into a shared library:
|
|
|
|
ld -b -o <modName>module.sl <object list>
|
|
|
|
The -b tells the linker to produce a shared library.
