使用Cmake和Ninja限制ndkBuild的CPU内核 [英] Limit CPU cores for ndkBuild with Cmake and Ninja

问题描述

之前，当我使用ndkBuld在Android上构建本机代码时，我能够将参数传递给 make 来定义要使用的多个CPU内核。如果我想利用4个内核，我可以添加如下内容

Before, when I was using ndkBuld for building native code on Android I was able to pass an argument to make to define a number of CPU cores to be used. If I wanted to utilize 4 cores I could add something like this

externalNativeBuild {
    ndkBuild {
        arguments "-j4", "APP_SHORT_COMMANDS=true"
        abiFilters "armeabi-v7a"
    }
}

有人可以给我一个建议，我该如何使用Cmake和Ninja做类似的事情？ cmake配置是否有一些等效参数？

Can somebody give an advice how can I do something similar with Cmake and Ninja? Is there some equivalent parameter for cmake configuration?

externalNativeBuild {
    cmake {
        arguments "-DANDROID_STL=c++_static"
        abiFilters getAbis()
    }
}

谢谢。

推荐答案

好吧，这似乎是NDK中的错误/缺失功能。我已经与一些 NDK Google员工进行了交谈，他们也无法帮助我。希望它将在更高版本的NDK / AS中受支持。

Ok it seems it is a bug / missing feature in NDK. I've talked to some "NDK Googlers" and they were not able to help me either. Hopefully it will be supported in later versions of NDK / AS.
