Building and debugging Chromium using visual studio giving error : error LNK1112: module machine type 'x64' conflicts with target machine type 'X86' -

i want debug chromium code check how compiles javascript code. have downloaded chromium code , trying build cef solution file using visual studio getting following error:

error lnk1112: module machine type 'x64' conflicts target machine type 'x86' \third_party\libjpeg_turbo\jccolss2-64.obj cefclient

error msb3073: command "call ninja.exe -c ..\out\debug\ cefclient" exited code 1. d:\ishan\chromium\chromium\chromium\src\cef\cefclient.vcxproj cefclient

can me resolve error

thanks ishan jain

chromium can built on 64-bit windows, doesn't matter if building 32-bit on 64-bit. windows 7 x64 or later must.

seems have configured build 64-bit (if using ninja, set gyp_defines=target_arch=x64) building 32-bit, using
ninja -c out\debug. seems have configured 64-build building 32-bit.

64-bit build in debug_x64 (or debug_64, don't remember now). so:
- if configured target_arch=x64, build ninja -c out\debug_x64
- if configured target_arch=ia32 (or let empty, think default build 32-bit on windows), build ninja -c out\debug

afaik cannot build in same directory - maybe i'm wrong - both 32 , 64 build (because of generated .ninja files, mainly). if using set gyp_generators=msvs-ninja,ninja (mainly if generating visual studio solution), may work, msvs-ninja not supported, nor maintained (anymore).

edit: ninja build visual studio example.
vs external tools > add entry like:
title build libcef debug
command f:\dev\cef\2357\build.bat
(sources in f:\dev\cef\2357\x86\chromium)
arguments debug
initial directory f:\dev\cef\2357

layout (build branch 2357):
f:\dev\cef\2357 root directory
/
  automate-git.py
  build.bat
  x86/
    chromium/

build.bat file below; x86/ directory manually created. under x86 have checkout of chromium (cef , depot_tools appear under x86/).


my build.bat file (details can figured out):
