如何使用忍者在cmake中复制命令行参数? [英] How can I replicate a command line arguments in cmake with ninja?

问题描述

我正在使用一个android(基于clang)编译器，我想使用该编译器使用CMake编译android项目.与命令行参数能够编译项目，我想用忍者在CMake中复制相同的参数. 有效的命令行代码如下:

I'm having a android (clang based) compiler that i want to use to compile android projects using CMake. with command line arguments am able to compile the project and i want to replicate the same arguments in CMake with Ninja. Command Line Code that is working is as follows :

c:\myproj\backup\bin\myandroidcompiler.exe 
-isysroot C:\Users\Public\Documents\Android\AndroidNDK-9c_x86\platforms\android-14\arch-arm 
-idirafter =\usr\include 
-idirafter C:\Users\Public\Documents\Android\AndroidNDK-9c_x86\sources\cxx-stl\gnu-libstdc++\4.8\include 
-idirafter C:\Users\Public\Documents\Android\AndroidNDK-9c_x86\sources\cxx-stl\gnu-libstdc++\4.8\include 
-idirafter C:\Users\Public\Documents\Android\AndroidNDK-9c_x86\sources\cxx-stl\gnu-libstdc++\4.8\libs\armeabi-v7a\include 
-idirafter C:\Users\Public\Documents\Android\AndroidNDK-9c_x86\sources\android\native_app_glue  
-I c:\myproj\backup\dev\tp\include\android\fmx 
-isystem c:\myproj\backup\dev\tp\include 
-isystem c:\myproj\backup\dev\tp\include\android\crtl

我正在使用以下工具链文件:

I am using the following toolchain file :

#set(CMAKE_ANDROID_NDK_TOOLCHAIN_VERSION clang)

此工具链的输出如下:

-o CMakeFiles\androidcmakeexample.dir\src\main.cpp.obj -c ..\src\main.cpp

这里存在--sysroot(在底部)，而在命令行中我期望根本不添加-isysroot和idirafter参数.我尝试了很多可能性，但没有任何效果.我无法弄清楚哪里做错了.任何帮助将不胜感激.

Here --sysroot (present at bottom) is present, while in command line i expected -isysroot and idirafter arguments are not added at all. I have tried many possibilities but nothing worked. I am unable to figure out what am doing wrong. any help would be very much appreciated.

推荐答案

发布的命令行输出是用于构建单个源文件main.cpp:

The command line output posted is one for building a single source file, main.cpp:

-o CMakeFiles\androidcmakeexample.dir\src\main.cpp.obj

也许您缺少适当的CMAKE_CXX_FLAGS，它是CMake设置，用于指定如何编译C ++源文件.

Perhaps you are missing a proper CMAKE_CXX_FLAGS, which is the CMake setting that specifies how C++ source files are compiled.

尝试将以下内容添加到您的CMakeLists.txt:

Try adding the following to your CMakeLists.txt:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${ANDROID_LIBRARY}")
