Hence tools-discuss in the distribution list :) I consider it a necessary evil that GCC is in the bootstrap tool-chain and most likely the native build tool-chain as well. That was going to be the fate for PowerPC had it gotten that far. This is also a gap. I believe it is possible to build at least the OpenSolaris ON consolidation bits with GCC at the moment (although I am not certain of which version). GCC 4 compilation is not possible without at least some of those fixes I referenced, so I believe 3.x is required (at least that was the case with the PowerPC port from nv-56). Also, C++ compilation for other consolidations is going to be a sticky issue as the Sun C++ ABI is the preferred and (almost) required C++ ABI according to current ARC requirements. I believe, for the moment, that closing that gap would have to be a follow-on project. I want to see a port coming up to run levels > 1 before I go working on fixing layered software issues. On that note, this brings up other issues such as distribution and testing down the road. I would like to suggest that the scope for this project be to simply bring up the port for recent versions of the ON, SFW, and X consolidations and I would look to the Emerging Platforms Community to assist in creating follow on projects to close distribution, testing, and developer p & p gaps. As items come up that need to be brought for ARC attention, I can at least lead some of those tasks. > > > Thanks > > ./C > -------------- next part -------------- An HTML attachment was scrubbed...
