Question

如何使用Android目标构建Google protobuf（c ++版本，https://github.com/google/protobuf/releases/latest）？

Answer 1

我在没有ndk-build的情况下编译了protobuf。这是脚本（不是很干净，但它有效）：

rm -rf /tmp/protobuf-3.3.0/
tar xzvf ~/Downloads/protobuf-cpp-3.3.0.tar.gz -C /tmp/
cd /tmp/protobuf-3.3.0/
export NDK_ROOT=/home/user/SDKS/ANDROID/NDK/android-ndk-r13b
export SYSROOT=$NDK_ROOT/platforms/android-9/arch-arm
export PREBUILT=$NDK_ROOT/toolchains/arm-linux-androideabi-4.9
export LDFLAGS="--sysroot=$SYSROOT"
export LD="$NDK_ROOT/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/arm-linux-androideabi/bin/ld $LDFLAGS"
export LIBS="-llog $NDK_ROOT/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi-v7a/libgnustl_static.a"
export CPPFLAGS=""
export INCLUDES="-I$NDK_ROOT/sources/cxx-stl/gnu-libstdc++/4.9/include/ -I$NDK_ROOT/platforms/android-9/arch-arm/usr/include/ -I$NDK_ROOT/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi-v7a/include/"
export CXXFLAGS="-march=armv7-a -mfloat-abi=softfp -DGOOGLE_PROTOBUF_NO_RTTI --sysroot=$SYSROOT"
export CCFLAGS="$CXXFLAGS"
export CXX="$PREBUILT/prebuilt/linux-x86_64/bin/arm-linux-androideabi-g++ $CXXFLAGS"
export CC="$CXX"
./autogen.sh
./configure --host=arm-linux-androideabi --with-sysroot=$SYSROOT --enable-cross-compile --with-protoc=protoc --disable-static --enable-shared CXX="$CXX" CC="$CC" LD="$LD"
make
cp -v /tmp/protobuf-3.3.0/src/.libs/* ~/git/project/build/protobuf_android/

这是probs矫枉过正，因为我在另一个项目中使用它，所以依赖性过多但是......

protobuf aarch64/arm Android.mk

谷歌protobuf和Android NDK
