使用bazel为ARM交叉编译libjpeg_turbo

Question

我正在尝试构建https://github.com/google/vr180，最后一次更新是5年前，但我想在我的设备上使用3D相机尝试该应用程序。

我已经修复了很多问题，你可以在这里找到： https://github.com/google/vr180/compare/master...cashlo:vr180:master

我现在遇到的错误是编译 libjpeg_turbo:

我想需要通过在 BUILD.libjpeg_turbo 文件中使用 ARM 版本的 gcc 来修复？

Answer 1

这是由 Bazel 7.0 中的更改引起的，添加标志

--noincompatible_enable_android_toolchain_resolution

修复了该问题。
