Description Jakub Daniel 2013-02-18 20:01:33 UTC

VFP patch from the ebuild is not enough. It was not even enough to add armv7=false and vfp3=off to the make options in the ebuild. I also had to modify build/standalone.gypi and change the default armv7 to 0 and arm_fpu% to vfpv2 instead of vfpv3 to build.

Reproducible: Always

Steps to Reproduce:
1. Get RPi
2. Try to emerge v8-3.15.11.15 on it
3. Watch it fail

How about posting your modifications here? How about submitting them upstream? See https://code.google.com/p/v8/wiki/Contributing

Please post the build log and the fix if you have one.

I explained what i changed. The change is only a workaround for RPi... I dont know how to fix it properly, I really dont understand how the build process detects platform. I attempted to ask about that on irc. I created an issue about vfp3 on code.google.com of v8. I have similar problems with different google projects.
