android make debug : (.ARM.exidx+0x0): error: undefined reference to '__aeabi_unwind_cpp_pr1'

前言

看到一个makefile编译后, 出现了编译错误.
最后一个错误是

D:\android-ndk-r10e\toolchains\arm-linux-androideabi-4.9\prebuilt\windows\bin\arm-linux-androideabi-g++ -ID:\android-ndk-r10e\toolchains\arm-linux-androideabi-4.9\prebuilt\windows\lib\gcc\arm-linux-androideabi\4.9\include-fixed -ID:\android-ndk-r10e\platforms\android-19\arch-arm\usr\include -LD:\android-ndk-r10e\platforms\android-19\arch-arm\usr\lib -lc -lgcc -Bdynamic -nostdlib -fpic -ldl -o mysharedlibary mysharedlibary.o D:\android-ndk-r10e\platforms\android-19\arch-arm\usr\lib\crtbegin_dynamic.o D:\android-ndk-r10e\platforms\android-19\arch-arm\usr\lib\crtend_android.omysharedlibary.o(.ARM.exidx+0x0): error: undefined reference to '__aeabi_unwind_cpp_pr1'collect2.exe: error: ld returned 1 exit statusmake: *** [all] Error 1

在网上查资料，自己再做试验，解决了.
要加一个库libgccunwind.a, 那个库里有’__aeabi_unwind_cpp_pr1’
我用android-ndk-r10e做的试验.
