[Numpy-discussion] libnumarray.h and NO_IMPORT_ARRAY

We're currently porting several of our boost-wrapped Numeric classes to numarray. The routines are spread across several cpp files, and **libnumarray_API is needed in each file. In Numeric, we invoke import_array() in the module file, to initialize **PyArray_API, and def NO_IMPORT_ARRAY in the other files; this produces extern void **PyArray_API in those files, and everyone's happy. Currently libnumarray.h doesn't implement this -- is there another way to compile a multiple file project which initializes the API just once? Thanks, Phil Austin
