build fail: __int128 is not supported on this target

[Joe-Gibbon]

Hello fellow eos enthusiasts

I'm unable to build eos locally due to __int128 is not supported on this target. Would appreciate any workaround advice so I can build out, get busy building blocks and making contracts :-)

Kind regards
Joe Gibbon

I get exactly same problem. My OS is ubuntu 17.10 . I'm looking for resolution as well.

[LonRock]

I think the reason is because 32bit OS, compiler cannot support both amd64 and i386. I changed to 64bit ubuntu 17.10 the problem is gone. Though there're some other problems.

I'm compiling EOS fc library on Raspberry Pi 1b, having the same __int28 problem for uint128.cpp.

Raspberry Pi 1b is a 32bit ARM CPU.

@ganioc 道友你好，关于 int128 不支持 x86 的问题，请问最后如何解决的？
我们目前也是在 iPhone 5C 上遇到这个问题，5C是 x86 架构，不支持 64位。

请问解决了么？（手动狗头
