构建工具链与cmake的交叉编译为Android [英] Building a toolchain with cmake to cross-compile for android
问题描述
gcc (GCC) 4.8.1
android-ndk-r9
您好，
我的主机是的Fedora 19 ，我想创建一个工具链编译程序在Android上运行的，后来我想延长这种适用于iOS。
My host machine is Fedora 19 and I want to create a tool-chain for compiling programs to run on android, later I want to extend this for iOS.
我收到以下错误：
Check for working C compiler: /opt/ndk/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc -- broken
我不知道为什么我收到这个错误，因为一切都已经安装。我还安装了的binutils-臂Linux的GNU 。不过，这是我第一次做这种类型的事情，所以很多我已经得到的东西混合起来。
I am not sure why I am getting this error, as everything has been installed. I have also installed binutils-arm-linux-gnu. However, this is my first time do this type of thing, so many I have got something mixed up.
我试图使用cmake来croos编译在Android设备上运行库创建工具链文件。
I am trying to create a toolchain file using cmake to croos-compile to run libraries on an android device.
我已经安装了Android的NDK-R9在以下位置的路径编译：
I have installed the android-ndk-r9 in the following location with the path to the compiler:
/opt/ndk/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin
arm-linux-androideabi-addr2line
arm-linux-androideabi-ar
arm-linux-androideabi-as
arm-linux-androideabi-c++
arm-linux-androideabi-c++filt
arm-linux-androideabi-cpp
arm-linux-androideabi-elfedit
arm-linux-androideabi-g++

arm-linux-androideabi-gcc-ar
arm-linux-androideabi-gcc-nm
arm-linux-androideabi-gcc-ranlib
arm-linux-androideabi-gcov
arm-linux-androideabi-gdb
arm-linux-androideabi-gprof
arm-linux-androideabi-ld
arm-linux-androideabi-ld.bfd

arm-linux-androideabi-readelf
arm-linux-androideabi-run
arm-linux-androideabi-size
arm-linux-androideabi-strings
arm-linux-androideabi-strip
我的交叉编译的文件是：
My cross-compile file is:
include(CMakeForceCompiler)
set(toolchain_path /opt/ndk/toolchains)
# Target system
set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_SYSTEM_PROCESSOR arm)
set(CMAKE_SYSTEM_VERSION 1)
# Compiler to build for the target
set(CMAKE_C_COMPILER /opt/ndk/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc)
set(CMAKE_FIND_ROOT_PATH /opt/ndk/toolchains)
我在根目录下我的工具链是运行这个从我构建/调试目录。
I run this from my build/debug directory with my toolchain being in the root directory.
[ant@localhost debug]$ cmake -DCMAKE_TOOLCHAIN_FILE=arm-eabi-gcc.cmake ../..

在事先非常感谢，
推荐答案
我设法先收拾一下这个网站来解决这个问题：
I managed to solve the problem by first going to this website:
http://developer.android.com/tools/sdk/ndk/index.html
有是使用自带的NDK独立工具链的一个例子。
There is an example of using the standalone toolchain that comes with NDK.
make-standalone-toolchain.sh --toolchain=arm-linux-androideabi-4.8
在提取到我的/ opt目录。
Extracted the into my /opt directory.
和使用此示例工具链的CMake文件
And using this sample toolchain cmake file
# Target system
set(CMAKE_SYSTEM_NAME Android)
set(CMAKE_SYSTEM_VERSION 1)
# Compiler to build for the target
set(CMAKE_C_COMPILER /opt/arm-linux-androideabi-4.8/bin/arm-linux-androideabi-gcc)
set(CMAKE_CXX_COMPILER /opt/arm-linux-androideabi-4.8/bin/arm-linux-androideabi-g++)
一切之后只是工作。但是，我不能让我的previous问题的工作。也许我错误地设置了一些环境变量，以错误的路径。
Everything just worked after that. However, I couldn't get my previous problem working. Maybe I have set some environmental variables incorrectly to the wrong paths.
希望这可以帮助其他人。
Hope this helps someone else.
