【转】解决使用NDK开发Android应用时.c/.cpp 中有错"syntax errors"，不是真正的错误

转载自http://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-development/

Your .c/.cpp file (native.c in my case) contains a lot of syntax errors which are not truly syntax errors. This is because Eclipse threats the project as a pure Java project. We have to convert the project into mixed Java & C/C++ project.

5) Press Ctrl+n (or choose File->New->Other… from main menu) and selectConvert to a C/C++ Project.

This will convert your project into a mixed Java & C/C++ project rather than into pure C/C++ project (the name of the function is misleading).

Click Next. Then choose your project and below choose Makefile project and – Other Toolchain –. Click Finish.

After doing this Eclipse will ask you if you want to switch to C/C++ perspective. ChooseYes because otherwise you wouldn’t be able to set C/C++ build preferences.

6) Click on your project with right button and select Properties or press Alt+Enter

Properties windows will appear. Here you have to configure use of ndk-build instead of make all command and set proper include paths.

7) Choose C/C++ Build and configure ndk-build as a build command

In Builder settings fill ndk-build into Build command entry. You have to uncheck Use default build command. You also need to have ndk-build script in your PATH.

In Behaviour setting uncheck clean (ndk-build cleans project automatically on build and does not support separate clean command) and clear all text from build (ndk-build does not accept all as a parameter.

Click Apply to save settings.

8) Choose C/C++ General->Paths and Symbols and configure include path

In Includes tab choose GNU C or GNU C++ and click Add… button. Add path to include directory which is located in platforms/android-4/arch/arm/usr/include subdirectory of place where you’ve unpacked Android ndk. Include path depends on target for which you are compiling (android-4 in my case — i.e. Android 1.6).

Finally click Apply and OK and that is all. Now you can use all Eclipse power for editing your C/C++ sources. If you click Run or Debug Eclipse will compile C/C++ code as well as Java code and run it on device/emulator. However you will not be able to debug C/C++ code.
