Re: [v8-users] link to libv8_base.a: error adding symbols: File format not recognized

[Todd Wong]

Thanks, Ben.

I've solved this by disable cfi and lto (is_cfi=false use_thin_lto=false).

And google deleted 2 replies from me, I don't why.

Fix your PATH or hack the `ar = ...` rule in build.ninja?
