Hi Andrew,

Thanks. Looks like I should have read all of find_libca. (Also, I missed that the first message mentioned dclaring PYEPICS_LIBCA).

Actually pyepics was designed to use the regular libca.so library, it
doesn't have its own python-specific one so it doesn't need a C compiler
to build and use. This is unusual, but it's one of the nice things about
our having a C API for CA, pyepics can use the ctypes ffi to call it
directly.

This kind of thing is not generally possible with C++ APIs though.
