| 5 | There are two important points. First, the python executable must be |
| 6 | linked with the -E option to explicitly export all symbols. This |
| 7 | works with the vanilla interpreter, but I am not sure how friendly it |
| 8 | will be when I try to embed the interpreter in a larger application. |
| 9 | It may be necessary to hand tune the exports using the -e option. |
| 10 | Anyway, the additional flag to $(CC) is "-Wl,-E", which passes the -E |
| 11 | flag to the compiler. My link line (from an actual run) looks like |
| 12 | this: |
| 13 | |
| 14 | cc config.o -Wl,-E libModules.a ../Python/libPython.a ../Objects/libObjects.a ../Parser/libParser.a -lm -ldld -o python |
| 15 | |
| 16 | Second, the dynamic module must be compiled with the +z option to make |
| 17 | it position independent and then linked into a shared library: |
| 18 | |
| 19 | ld -b -o <modName>module.sl <object list> |
| 20 | |
| 21 | The -b tells the linker to produce a shared library. |
