Building mozilla-central with clang + icecream
I tried to build m-c today with clang 5.0 and icecream using the following
mozconfig:
```
mk_add_options MOZ_MAKE_FLAGS="-j$(icecc-jobs)"
mk_add_options 'export CCACHE_PREFIX=icecc'
mk_add_options "export RUSTC_WRAPPER=sccache"
export CC=clang
export CXX=clang++
ac_add_options --with-ccache
```
The result is an error during config:
```

I know I can build using gcc+icecream or using clang without icecream, but does
anyone know how to combine clang and icecream to make it work?
Thanks,
zb.

I'm using this setup daily (with clang trunk from some weeks ago, not 5.0, but it's the same really), here is my mozconfig: ``` export CC="icecc clang" export CXX="icecc clang++" mk_add_options MOZ_MAKE_FLAGS="-j100" # adjust, this is good for the paris office mk_add_options 'export RUSTC_WRAPPER=sccache' mk_add_options 'export CARGO_INCREMENTAL=1' ``` Cheers, Paul. ___ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform

Also sprach p...@paul.cx: I'm using this setup daily (with clang trunk from some weeks ago, not 5.0, but it's the same really), here is my mozconfig: ``` export CC="icecc clang" export CXX="icecc clang++" mk_add_options MOZ_MAKE_FLAGS="-j100" # adjust, this is good for the paris office mk_add_options 'export RUSTC_WRAPPER=sccache' mk_add_options 'export CARGO_INCREMENTAL=1' ``` I use this in the London office: mk_add_options MOZ_MAKE_FLAGS="-j90" mk_add_options 'export RUSTC_WRAPPER=sccache' mk_add_options 'export CCACHE_PREFIX=icecc' export CC=/usr/lib/icecc/bin/cc export CXX=/usr/lib/icecc/bin/c++ But I sense there is opportunity to abstract some of this complexity away in the build system once sccache gets integrated properly. (Is there a plan to make it mandatory? Could it replace ccache for C++?) ___ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform

Yeah, tried the same thing and got:

Maybe it's just the SF Office icecream instance?

Probably icecc-create-env can help. It will create a standalone toolchain package: /usr/lib/icecc/icecc-create-env --clang /usr/bin/clang-5.0 /usr/lib/icecc/compiler-wrapper Then export ICECC_VERSION="" in your mozconfig. -- Wei-Cheng Pan ___ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform

Unfortunately, that still doesn't make it fly.
My mozconfig:
```

Any idea what's causing it?

The version shipping with ubuntu in particular is rather old, and there’s a few bugs related to races causing intermittent failure. Those problems have almost all disappeared using icecream 1.1 for me. I still have intermittent build failures however. I often have a ./mach build following a ./mach clobber to completing successfully and restarting the build will then complete with no trouble. so there’s still races out there. I run icecream with clang as compiler… JY ___ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
