如何为UCS4编译numpy [英] How do I build numpy for unicode ucs4

问题描述

我正在使用yocto交叉编译嵌入式设备-因此不宜使用pip install.

I am cross compiling for an embedded device using yocto - so using pip install is not appropriate.

我的构建工作正常，但是默认使用ucs2字符类型，这会导致错误: numpy.core.multiarray导入失败.

My build works, but keeps defaulting to ucs2 character type, which causes an error: numpy.core.multiarray failed to import.

推荐答案

注意，我还没有真正尝试过...

Caveat, I haven't really tried this...

据我所知，使用ucs4支持构建numpy意味着您必须使用ucs4-support编译python.因此，您需要添加

As far as I can see, building numpy with ucs4 support means that you have to compile python with ucs4-support. Thus, you would need to add

 EXTRA_OECONF += "--enable-unicode=ucs4"

在python_xxx.bb附录中，具体取决于您使用的是python(2或3)以及OE发行版.

in a python_xxx.bbappend, depending on which python (2 or 3) and which OE-release you're using.

如果在此之后还有其他问题，则未知...

If you're getting any other issues after this, is unknown...
