Bug 601046 – llvm-3.8.1 build failed on Sierra using prefix

• Product: Gentoo/Alt
• Status: RESOLVED FIXED

[Description Xi 2016-11-28 05:21:01 UTC]

I tried to install Gentoo-prefix on my mac os. My mac os is x86_64, Sierra. I started the "bootstrapping-prefix.sh" script and used default for all options. The build when well for all the other packages. llvm was the last one to build, and it failed with following messages:

x86_64-apple-darwin16-clang-3.5.2: error: unable to execute command: Segmentation fault: 11

llvm.error

I set the MAKEOPTS="-j1" and tried again. This time, the error message looks very different. Please check.

Hi Xi,

if you want to finish the bootstrap. you can mask this packages ( Not this is temporary solution):

>sys-devel/llvm-3.5.2 
>sys-devel/clang-3.5.2-r100
>sys-libs/libcxxabi-3.8.1
>sys-libs/libcxx-3.5.2
>sys-libs/libcxx-headers-3.5.1

Add missing info.

When I first started building prefix, I hit bug #598336. Then I applied the patch suggested by Emre.

After I added that mask, building llvm seem passed. But the build failed at building glib.

This is happening for me as well, and it was also reported by another user on IRC.

I've fixed this.
