无法使用Yocto生成Windows的SDK [英] Can't generate SDK for Windows with Yocto

问题描述

我已经为飞思卡尔imx6qpsabreai开发板和带有工具链的SDK构建了Linux映像，该映像在Linux上运行良好.

I've build a Linux image for freescale imx6qpsabreai board and SDK with toolchain which works well on Linux.

现在，我想支持Windows上的开发并遵循这我发布的帖子

Now I want to support development on Windows and following this post I've

• 将 oe meta-mingw 下载到 sources/meta-openembedded/meta-mingw
• 在我的项目中将SDKMACHINE = x86_64-mingw32添加到local.conf中

但是，我无法以这种方式构建新的SDK.

however, I can't build new SDK this way.

我也不是经验丰富的C/C ++程序员，但是从我的角度来看，mingw不包含用于arm体系结构的编译器，所以也许我只是无法在Windows上使用arm工具链?

Also, I am not an experienced C/C++ programmer, but from my point of view mingw doesn't contain compiler for arm architecture, so maybe I just can't get arm toolchain to use on Windows?

推荐答案

meta-mingw构建了从Linux到Windows(mingw)的交叉编译.然后，它使用此交叉编译器构建从(mingw)到目标SDK环境的标准工具链.您使用的层正确，但是存在其他问题.

meta-mingw builds a cross compile from Linux to Windows (mingw). It then uses this cross compiler to construct a standard toolchain from (mingw) to the target SDK environment. You are using the correct layer, but have a different problem.

您似乎正在使用期望较新的bitbake语义的层(meta-mingw):

It appears that you are using a layer (meta-mingw) that is expecting the newer bitbake semantics:

 0027:    if d.getVar("TARGET_OS") != "linux":

*** 0028:返回异常:TypeError:getVar()缺少1个必需的位置参数:"expand"

*** 0028: return Exception: TypeError: getVar() missing 1 required positional argument: 'expand'

Bitbake以前需要'd.getVar'两个参数，现在只需要一个(第二个是可选的).

Bitbake used to require two arguments to 'd.getVar', and now only requires one (the second is optional).

我建议您确定所使用的oe-core/poky版本，并获取匹配的meta-mingw版本.(它可能像签出正确的分支一样简单.)

I would suggest that you identify which version of oe-core/poky you are using and get a matching version of meta-mingw. (It may be as simple as checking out the correct branch.)
