Okay, I'll go with a stable Clang like v3.3. Have to build it myself, though, as Debian comes with v3.0. No, I didn't try using libstdc++. I'll give it a shot. The machine is going to be turned on 24/7 until it dies from old age, so I don't know if it is worth scheduling in a special manner. The worst part is linking as I cannot use Gold because I get an error about an unsupported relocation time. -- Mikael 2013/11/18 Shankar Easwaran <shankare at codeaurora.org>> On 11/18/2013 11:57 AM, Mikael Lyngvig wrote: > >> I'm in the process of configuring a Mac Mini G4 (PowerPC, big-endian) to >> be >> an LLD buildbot slave, as there were some who wanted a big-endian tester >> of >> LLD. >> >> I have a few quick questions with respect to that: >> >> 1.

Note that the libstdc++ on OS X (4.2) is probably too old to use c++11, which is required by lld. Cheers, Rafael
It is running Debian 7.2. -- Mikael 2013/11/18 Rafael EspĂndola <rafael.espindola at gmail.com>> On 18 November 2013 13:25, Mikael Lyngvig <mikael at lyngvig.org> wrote: > > Okay, I'll go with a stable Clang like v3.3.
