[open-axiom-devel] FFI change 1.3 -> 1.4?

[Arthur R. <ar...@ma...>]

Hi Gaby,

Your FFI Example for scalar product compiles in 1.3 but not 1.4.  Can 
you tell me what the difference is?  I copied the C file to 
dot-product.c and the spad file to dot-product.spad.  In 1.4 I get an 
error: invalid signature.

Here are the outputs, first for OpenAxiom 1.3:

However for OpenAxiom 1.4 I get this:
