Building 64-bit Chromium


  • 64-bit builds will be the default when compiling on 64-bit Linux.

Mac OS X

  • Run the following command prior to building: build/gyp_chromium -Dtarget_arch=x64 -Dhost_arch=x64


  • The default GN build will match that of the host OS (so 64-bit Windows will give 64-bit builds). The default GYP build is 32-bits on all Windows variants. 
  • To force 64-bit building in GYP, run the following command prior to building: python build\gyp_chromium -Dtarget_arch=x64 and use either the Release_x64 or Debug_x64 build directory with Ninja
    (e.g. "ninja -C out\Debug_x64")
