How to compile c++11 code with android ndk and eclipse?
Regarding your first question:
Go to Project > Properties > C/C++ General / Paths and Symbols
In the "Includes" tab, add the proper directory, e.g. /android-ndk-r8d/sources/cxx-stl/gnu-libstdc++/4.7/include
Regarding your second question, I'm also looking for an answer. It is absolutely not clear how to define the GXX_EXPERIMENTAL_CXX0X macro in Eclipse.
Some say that it should be "added as a predefined macro to the indexer", but it looks like we both could not find a way to implement that...
I have read elsewhere that it should be added to "C/C++ General / Paths and Symbols / Symbols / GNU C++" but I can't find the "Symbols / GNU C++" part in my version of Indigo.

I'm using android NDK r8d, and eclipse Juno. I'm trying to compile C++ code which uses C++11 stuff like
mutex
,lock_guard
,shared_ptr
, etc. in a native android project in eclipse.I get errors like:
"error: 'shared_ptr' is not a member of 'std'"
"fatal error: mutex: No such file or directory"
I came across a similar question here. It seems to work for them, but the explanation there is not complete so I can't get it to work for me.
I added
"NDK_TOOLCHAIN_VERSION=4.7"
to theApplication.mk
and"LOCAL_CFLAGS += -std=c++11"
toAndroid.mk
file. Still, it doesn't compile.In the link above it says:
"Be sure that the standard library include path (like /android-ndk-r8d/sources/cxx-stl/gnu-libstdc++/4.7/include) is in the target settings."
How and where do I insert it?
I also get errors in eclipse IDE (on the source, before compiling). I know I should define
"__GXX_EXPERIMENTAL_CXX0X__"
to resolve them but I just don't know where to put it.So, if someone could post an answer with a full explanation of how to compile and make eclipse work with C++11 it would be great.

DeathlessHorsie about 11 yearsI use eclipse Juno and I also don't have the "Symbols / GNU C++" part, and without defining "GXX_EXPERIMENTAL_CXX0X" the indexer wont recognize the c++11 stuff. Did you managed to compile your code with the ndk?

Ariel Malka about 11 yearsYes, the (C++11) code compiles fine with the NDK. The problem is only at the level of indexing inside Eclipse.
