BeOS & Derivatives Haiku's 64bit port is progressing nicely. "As you can see, this looks pretty much like a regular Haiku desktop. There's still a lot of things missing, though - not many apps or drivers yet. However, most things should be fairly simple to get working, typically just a few compilation fixes."

doesn't Haiku already do this for the Hybrid? So, let's assume 64bit would be entirely Gcc4 (because, why wouldn't it?) does that mean 3 sets of libraries? Gcc2.x 32bit, gcc4.x 32bit, gcc4.x 64bit??? This seems quite an excessive amount of binaries! But I'm guessing it would be needed to support all 3 architectures.

Edit: I think my main point here is that Gcc2.x is necessary to support legacy BeOS closed source apps (the original goal of Haiku back when it was called Open BeOS) but gcc4 is required to support some of the newer stuff (hence hybrid) and that addind a new architecture (64bit) will double the required base libraries (if not more of the OS level executables)

x86_64 is gcc4 only, gcc2 is for x86 only.

...does that mean 3 sets of libraries?

Yes, each application needs to be packaged into 3 binaries, one for x86 gcc2, one for x86 gcc4, and a third for x86_64.

Right now it is difficult enough to maintain separate x86 gcc2 and gcc4 packages, x86_64 will add a 3rd. This is a good opportunity for the package manager and IDEs to make this easier by automatically generating "Fat" binaries that run on all architectures.

However, this is a problem that must not be solved immediately because the official Haiku R1 release will be x86 gcc2h (32-bit). Official x86_64 support will come in R2.

Agreed. There is probably no viable port of GCC 2.95 for 64bit. If there is, I see absolutely zero reason to use it for 64bit support. Like I said "why would you?"
