Error installing +universal variant of ICU port in SnowLeopard

[kasty.jose@…]

The following alternatives work ok:

> sudo port install icu
> sudo port install icu +x86_64   (however it builds i386 binaries instead of x86_64)
> sudo port install icu +i386

The following alternative does not work (+universal = i386 x86_64):

> sudo port install icu +universal

This is a SnowLeopard 10.6.2 OSx86 running on top of a VirtualBox VM. I succesfully installed universal variants of bzip2 and zlib ports. My mach_kernel is 32-bit, but I read somewhere that it can execute both i386 and x86_64 binaries.

Note that the icu port doesn't actually have variants named "i386" or "x86_64". The kernel arch is irrelevant, but the CPU arch of the VM is not. If you're running on a 32-bit processor, real or virtual, you won't be able to build icu for x86_64.

r79660 should make this possible. It's still pretty pointless to build a 64-bit binary on a 32-bit system unless you're planning to distribute it to other systems though.

[kasty.jose@…]

Thanks. I'm developing a plugin as a dynamic library and it should be available for a 32 and 64 bit app. The plugin is compiled against a static version of boost libraries. As boost dependes on icu, building the universal variant of boost requires the universal variant of icu.

Replying to jmr@…:
