build log for llvm 3.5

I have been trying to get around this error for two months. I cant get prefix set up on my system. llvm 3.5 fails telling me that I need a libstdc++ newer than 4.7. My system is OS X 10.7.5 (Kernel Version 11.4.2) I have tried to work around this with no success. Using more modern C compilers than those supplied by xcode, via macports, hasn't helped. Please help.

I've tried working around this in

Thank you! I will give this a try tomorrow.

No dice, same error, same build :(

build log from work around.

I was wrong. It's the same spot but a different error, and I don't quite get what it's telling me.

that would mean 'std' is somehow incompatible, we'll have to figure out why

Can is it libstdc specifically?

[Comment 7 Fabian Groffen 2016-03-06 08:34:38 UTC]

it seems like we need one, but libstdc++ 3.5 should be installed here

I think I hosed some dep because my platform provides this lib, so I didn't notice.

[Comment 8 Fabian Groffen 2016-03-06 08:44:43 UTC]

What version of OSX are you installing on?

Also, do you have llvm-3.4.2 installed in your bootstrap prefix now?

[Comment 9 stelicho 2016-03-07 05:53:30 UTC]

I'm on OS X 10.7.5 Lion (Darwin 11.4.2)

stage2.log says:

>>> sys-devel/llvm-3.4.2 merged.
 * Messages for package sys-devel/llvm-3.4.2:
 * Failed to set PT_PAX markings -m Release/bin/llvm-rtdyld.

I guess I should ask, where should I see it installed in the prefix? it's not in /usr/bin

[Comment 11 Fabian Groffen 2016-03-12 08:20:57 UTC]

the early stages will install stuff in tmp/usr/bin, I think the problem originates here, since the libs and stuff may be in two different locations

[Comment 12 Fabian Groffen 2020-12-13 17:02:40 UTC]

we moved away from llvm/clang on macOS
