#342: Add CCTK_POINTER_SIZE make variable -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: Keywords: flesh | -------------------------+-------------------------------------------------- It is sometimes necessary to know in a thorn's configuration script whether 32 bit or 64 bit code is to be generated. See the discussion in ticket #339.
The attached patch adds a CCTK_POINTER_SIZE make variable to make.config.defn which is accessible as a shell variable to configuration scripts. This will be 4 when compiling for 32 bit, and 8 when compiling for 64 bit.
I am not very expert in autoconf, so the patch might have to be modified. It seems to work, however.
I have not included the generated configure script - this should be generated by the person who commits the final patch.
