[Python-Dev] Solaris family and 64 bits compiling (original) (raw)

I actually agree. I am not sure yet, but I am thinking that adding a "--build-64" parameter to "configure" could be an option under Solaris. Most OSs (let say, Linux) force you to choose 32/64 bits at install time

Actually, that's not at all the case. Most systems these days support 32-bit and 64-bit applications simultaneously, and also support compiler tool chains that allow building for either mode. Solaris, Linux, and Windows are about on-par in this respect; OS X is more advanced as it allows to have a single binary that supports both 32-bit and 64-bit execution (making the need for adjusted path names irrelevant).

Since choosing 32 or 64 bits when compiling python under Solaris change the requirement, paths, etc., automating it should be a goal.

PS: Martin, is there any reason to restrict the solaris 10 buildslaves to 32 bits, beside the said problems?.

I don't see that as a restriction. I have to make a choice, and there are sooo many choices to make:

I picked the combination which was most easy to setup, and is therefore likely to be used by most users (except for those who think 64-bit is somehow "better" than 32-bit, when it is actually the other way 'round - IMO).

As for configuration, I personally prefer that setting CC indicates what type of build you want. Set CC to "gcc -m64" to indicate a 64-build. Ideally, you will not have to adjust library paths, since the other compiler will know on its own where to search things.
