I compile and link Python extension modules using the script
gcc -fPIC -g -I/usr/local/include/python2.3 \
-Wall -Wstrict-prototypes -c mymodule.c
g++ -shared mymodule.o -L/usr/local/lib -o mymodule.so
It works for me but it isn't pretty. Is there a better way to write it?
Gcc finds all the libraries that need to be linked in. For example,
does gcc do this?
I created a .so file "utilities.so" that contains some C functions that
are called in mymodule.c but are not visible from Python. Both
"utilities.c" and "mymodule.c" use numarray. What changes do I make in
the script above? Must I use the nasty "libnumarray_UNIQUE_SYMBOL" trick?
What is a script for creating "utilities.a" using gcc? How do I change
the script above to include "utilities.a"?
