avx wants dietlibc, most are ok with dietlibc or uClibc. I dont think curie is full-featured enough (from what magnus tells me).
That does raise a question, with all these embedded C libraries, are they ideal for the job and complete enough?

I think we should target a single C library and focus our efforts on it alone.
EDIT: And what are we using to replace Make and all them? |

leave them? Bsd ones?
No-one is saying "no GNU", just less bloat and less reliance on GNU

Use the best available imo

| Grrr... You can't compile C and C++ to bitcode! Oh well, like it matters. |

Bitcode is to LLVM as bytecode is to Java. |

Cool little web demo.

| Mh, I'd like to compile everything in portage except @system with ICC/glibc for starters, someone got an idea how to best do this? chroot? VM? System would be a Core i7 with 16GB and 2TB free space as of now. |

IIRC llvm-gcc is not well supported. Most of the development effort is behind clang.
When gcc 4.5 is released, dragonegg might be worth looking into.
I don't think replacing gcc with llvm will make systems faster or more stable. Replacing glibc with something like uclibc would, but that would break all sorts of shit. There is no drop in replacement for glibc. |

Seconded.
I have clang installed and use it wo build my (few) C programs. I'd be in for testing compilation of my system with clang.

Well, going from bash to sh would be a step forward imo.

Curie isn't at all intended to be a libc replacement.
It'd probably be better to start a new one from scratch, and just do it properly.

That's the trick to it all though. (Emphasis mine.)

It is portable, as long as you define portable to mean, "I can infect your system with my crap without any extra work." |

that's kind of what curie is doing though. but yeah it'd be quite the bitch to port all the current tools to it, since it's not only not similar in interface to posix, there's not a single function call that would be the same... which is good since it means the backup implementation just uses posix, meaning porting is far less of an issue.
there's so much wrong with the ansi libcs and posix though, it's surprising it's still that "popular". just thinking of all the *printf() shit makes me wanna stab someone.

What I was trying to says is this: If glibc doesn't follow the ANSI standards, isn't it broken? |
