Hello fellow dartisans,

I try to build the bleeding_edge release on a Ubuntu 12.04 LTS 64-bit machine, after preparing it according the wiki instructions and getting the sources successfully. Building the standalone Dart VM works and all tests pass.

When building the entire tree with the command ./tools/build.py--arch=x64

I got this error: ... in third_party/v8/src:

Error: #error Target architecture ia32 is only supported on ia32 host

…

Error 1: BUILD FAILED

The message seems to say clearly that v8 is only supported on a 32 bit os, but I find this hard to believe. I searched for an answer but could not find it, sorry if I overlooked it.

Could anyone clarify this error, and possibly suggest a work-around ?

Thanks!

Hi Ivo,

It seems like the V8 target architecture is not getting set properly. This worked for me on Ubuntu 10.04:

export GYP_DEFINES=v8_target_arch=x64

gclient runhooks

build.py --arch=x64

Thanks for the quick response Kevin!

This seems to have worked, in the output I get a BUILD FINISHED message somewhere, and everything in the out folder seems to be there.

One remark still, the build script does not complete normally, it now stalls at ACTION Running apidoc, but this is less important.
