fazibear commented 9 years ago

Trying to generate libuv, but with no luck

require 'ffi_gen'

FFIGen.generate(
  module_name: "LibUV",
  ffi_lib:     "libuv",
  headers:     %w[
                 uv.h
               ],
  cflags:      `llvm-config --cflags`.split(" "),
  prefixes:    [],
  output:      "libuv.rb"
)

with llvm-3.5.0_2 installed on Yosemite

here is backtrace

Works for me with libuv from Debian testing... which version do you have?

fazibear commented 9 years ago

Installed with brew: libuv-1.1.0 on Yosemite.

whitequark commented 9 years ago

0.10 here. I don't have a newer version in the repository.
