Compiling C++11 sources for Android NDK
android, android-ndk, c++, c++11
Solution
LOCAL_CPP_FEATURES += exceptions
LOCAL_CFLAGS += -std=c++11
Should go into Android.mk file. Alternatively, you could put
APP_CFLAGS += -std=c++11
into Application.mk. You can also use `APP_CPPFLAGS` instead, so that the C sources in your project (if you choose to add them) could compile (the C compiler will not like `-std=c++11`).
Problem
I'm trying to compile some C++11 sources with Android NDK on Windows, but without much luck. Please note, that I've read some other questions about compiling C++11, but they didn't help much unfortunately. I've downloaded the ADT Bundle and latest NDK (`android-ndk-r9b-windows-x86.zip`). These are my configuration files: Application.mk ``` APP_STL := gnustl_static NDK_TOOLCHAIN_VERSION = 4.8 LOCAL_CPP_FEATURES += exceptions LOCAL_CFLAGS += -std=c++11 ``` Android.mk ``` LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := procalc-core LOCAL_SRC_FILES := pcc_arithmetics.cpp \ pcc_arithmetics_tools.cpp \ pcc_common.cpp \ pcc_core.cpp \ pcc_dms_tokenizer.cpp \ pcc_dynamic_numerics.cpp \ pcc_exceptions.cpp \ pcc_expressiontree.cpp \ pcc_expression_containers.cpp \ pcc_messages.cpp \ pcc_numerics.cpp \ pcc_resolvers.cpp \ pcc_syntaxtree.cpp \ pcc_tokenizer.cpp \ sm_Bignum.cpp \ sm_Math2D.cpp \ sm_MathNumerics.cpp \ ss_Streams.cpp include $(BUILD_SHARED_LIBRARY) ``` Build command ``` cd %AndroidProjects%ProCalc\jni\ D:\Android\ndk\ndk-build pause ``` The error That's actually one of the errors, but it's clearly not recognizing new C++11 keywords like `auto` or `nullptr`. ``` D:/(path)/jni/pcc_arithmetics.cpp: In static member function 'static ProCalcCore::BaseNumeric* (* ProCalcCore::Arithmetics::GetFunctionMethod(std::string)) (const std::vector<const ProCalcCore::BaseNumeric*>&)': D:/(path)/jni/pcc_arithmetics.cpp:4077:11: error: 'nullptr' was not declared in this scope return nullptr; ^ ``` What am I doing wrong?
