| 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 |
| |
| 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. |
