Build 32bit windows target?

[m...@iceboy.org]

Hi,

Is there a way to build 32bit windows target using bazel? For example, can we cross compile 32bit target using VC from 64bit windows, or using mingw from linux?

Looks like the builtin configure script was hardcoded to use the 64-64 compiler under windows:
https://github.com/bazelbuild/bazel/blob/5947f474e152f7b1f447ef9c9392cd632c1fdd81/tools/cpp/windows_cc_configure.bzl#L226

I also tried to follow https://github.com/bazelbuild/bazel/wiki/Yet-Another-CROSSTOOL-Writing-Tutorial to define crosstool but with no success yet.

Any help will be appreciated.

Thanks!
Lu

Hi Lu,

Bazel itself only supports running on x64 platforms. But it's possible to use a x64-x86 compiler.

You can start from https://github.com/meteorcloudy/windows-crosstool and try to change the hardcoded path to the compiler you want.

Best,

Yun
