Because static one is faster than shared because of PIC optimization and some others. See: % python /usr/local/lib/python2.3/test/pystone.py Pystone(1.1) time for 50000 passes = 2.67188 This machine benchmarks at 18713.5 pystones/second % python-shared /usr/local/lib/python2.3/test/pystone.py Pystone(1.1) time for 50000 passes = 3.27344 This machine benchmarks at 15274.5 pystones/second I think python-shared isn't useful as libpython2.3.so and the only case when python-shared is useful will be this: python-shared -> xyzmodule.so extension module -> libxyz.so -> libpython2.3.so (where libxyz.so is doing both of extending and embedding) > Perhaps if BUILD_SHARED is specified then bin/python will be the shared > binary; and bin/python-static[2.3] would also be placed.

Doesn't really matter to me. Yes. It's too confusing. If anyone really wants to make his bin/python as shared binary, I will consider this again then. :) Thanks! Regards, Hye-Shik
