Compilation error on "array.C"

[jonilappalainen]

I'm trying to build but it fails. My gcc is version 4.4.2 and Perl is 5.10.1. I'm running osx 10.5.8 (Leopard).
It's somehow forced to try to compile with gcc-4.0 even when I have the 4.4.2. I manually linked the 4.4.2 version to point to gcc-4.0 but I'm still getting error:

The warnings and errors have to do with perls MULTIPLICITY option. I developed it with multiplicity, but it should be able to run without. You shouldn't worry about the warnings (though I agree they're ugly). The error on line 148 (a similar one exists in hash.C) is a bug. I just fixed locally and will upload it to github soon. There's a related but more complicated issue in the scalar binds, that will require more work :-(.

BTW, the reason it takes gcc-4.0 and not gcc-4.4 is probably because it picks the same compiler perl was compiled with. I think it's overridable by using the CC environmental variable but that may change in the near future as ExtUtils::CBuilder's C++ support improves.

Ok, thanks. I'll wait your update then. And yes, overriding the compiler using the CC environmental variable worked. I tried "perl Build.PL cc=gcc" before but that didn't work..

[Leont]

I hadn't thought of that, I should consider adding such an interface to my Build.PL/Build when I have the time

Hi Jon,

The latest version in git should compile without errors (assuming your perl comes with a shared libperl). There will be a lot of warnings though, I'm planning to get those out later.
