Re: [epp-dev] Mac OS X: No 64-bit packages?
|
Just in case someone following or stumbling on this topic is not already
aware: bug 281501 is tracking the request for 64-bit OS X builds:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=281501
Also, I've posted a screencast demo of how to (easily) construct your
own copy of the package contents using the SDK build and the install
wizard:

for some background.
You can't run eclipse in 64-bit mode on Mac OS X, because, even though
the cocoa-64bit bindings are available, all the downloads on
eclipse.org/download come in carbon (32-bit) and cocoa (32-bit)
flavours. I can respect the need to keep the number of packages down,
but this seems like the very worst possible combination! As you may
know, java 1.6 on mac os x only runs in 64-bit mode. Therefore, with
these packages you can run eclipse only in java 1.5, which is rather
annoying:
- java 1.6 is far faster than java 1.5.
- For those with the memory working on big projects, giving eclipse a
tonne of memory is nice, but of course that can only work in a 64-bit JVM.
- You can't use java 1.6 features when writing eclipse plugins for your
own use.
I therefore suggest any one of the following steps:
1. Replace the packages with "carbon 32-bit" and "cocoa 64-bit".
Apparently (see links at the top of this email) some people still need
the carbon build, but nobody could possibly need the 32-bit cocoa build,
as it's brand new!
2. Supply the 64-bit SWT jnilib and the 32-bit SWT jnilib in the same
cocoa build, so that the cocoa build is 32/64-bit agnostic and runs on
either. I presume this isn't as easy as it sounds otherwise someone
would have undoubtedly done this already.
