Trying to install on gentoo box but I get the following errors:

Any ideas?

Thanks!

Can you paste the output of uname -a and the contents of the RUBY_PLATFORM constant?

h0i commented 9 years ago

uname -a Linux somehost.ispgateway.de 2.6.32.53-grsec-x86_64 #4 SMP Wed Jun 11 14:57:07 CEST 2014 x86_64 Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz GenuineIntel GNU/Linux

Hm, there is no environment variable like RUBY_PLATFORM. "rvm info" shows no such constant either. Where can I find this constant?

ignisf commented 9 years ago

It's a constant in Ruby. You can print it with this command ruby -e 'puts RUBY_PLATFORM'

h0i commented 9 years ago

$ ruby -e 'puts RUBY_PLATFORM' x86_64-linux

Can I see the contents of RbConfig::MAKEFILE_CONFIG['build_cpu'], RbConfig::MAKEFILE_CONFIG['ARCH_FLAG'] and ['foo'].pack('p').size? Make sure you run it with the correct Ruby in RVM.

h0i commented 9 years ago

$ ruby -e "puts RbConfig::MAKEFILE_CONFIG['build_cpu']" x86_64 $ ruby -e "puts RbConfig::MAKEFILE_CONFIG['ARCH_FLAG']"

$ ruby -e "puts ['foo'].pack('p').size" 4 $ which ruby /kunden/somewhere/.rvm/rubies/ruby-2.1.2/bin/ruby

ARCH_FLAG returns nothing / seemes to be unset. What would be "the correct Ruby in RVM"? The one the gemset was created for?

Thanks!

ignisf commented 9 years ago

Oh wow... That's interesting... libv8 architecture detection fails due to the size of the pack being 4. I've opened the following issue in connection with this: https://github.com/cowboyd/libv8/issues/141

h0i commented 9 years ago

"g++ .../ia32.release/obj.target/..." sounded to me not sensible on an x86_64 machine but I don't now exactly. So I guess there is no workaround and I have to wait for the next release?

judgetr commented 9 years ago

i'm having the exact same issue, is there any update on this ?

ignisf commented 9 years ago

This will be fixed in libv8 4.5 by https://github.com/cowboyd/libv8/commit/3cbf1c3517ebd4aa447723713ee8ab2f542e14e9
