Android NDK: Including boost c++ library -

-

i trying use boost library inside android application, using ndk. have found couple of success stories here , here, can't same me. trying use library in this link, boost thread library. in code below, trying include thread library, not math library. process used build boost libraries pretty same first link attached.

so far, seems have built boost libraries, when run ndk-build, following error:

prebuilt       : libboost_thread.a <= <ndk>/sources/ cp: omitting directory `path/to/ndk/sources/boost' make: *** [obj/local/armeabi/libboost_thread.a] error 1

obviously cp: omitting directory... not error. thing i'm getting other next line, doesn't mean anything. error 1

here's android.mk file:

local_path := $(call my-dir) include $(clear_vars) local_static_libraries := boost_thread local_ldlibs := lboost_system-gcc-md lboost_thread-gcc-md -lgnustl_static local_ldlibs += lboost_system-gcc-md lboost_thread-gcc-md \          -l$(ndk_root)/sources/cxx-stl/gnu-libstdc++/libs/armeabi \          -lgnustl_static   local_src_files := #cpp_sources local_module := com_example_ndkfile_cppmethods include $(build_shared_library) $(call import-module,boost)

and there's android.mk file in path/to/ndk/sources/boost/:

local_path:= $(call my-dir)   include $(clear_vars)   local_module:= boost_thread local_src_files:= android/lib/libboost_thread.a   local_export_c_includes := $(local_path)   include $(prebuilt_static_library)

and humble application.mk file:

app_abi := armeabi armeabi-v7a app_stl := gnustl_static app_cppflags = -fexceptions

i built boost libraries using bjam. of libboost_###.a files in sources/boost/android/lib folder.

what error i'm getting?

i built boost libraries using boost-for-android. have in boost/include/lib directory android makefile boost.mk

local_path := $(call my-dir)  # boost_date_time # include $(clear_vars) local_module := boost_date_time local_src_files := libboost_date_time-gcc-mt-1_53.a include $(prebuilt_static_library)  # boost_filesystem # include $(clear_vars) local_module := boost_filesystem local_src_files := libboost_filesystem-gcc-mt-1_53.a include $(prebuilt_static_library)  # boost_thread # include $(clear_vars) local_module := boost_thread local_src_files := libboost_thread-gcc-mt-1_53.a include $(prebuilt_static_library)  # boost_system # include $(clear_vars) local_module := boost_system local_src_files := libboost_system-gcc-mt-1_53.a include $(prebuilt_static_library)  # boost_program_options # include $(clear_vars) local_module := boost_program_options local_src_files := libboost_program_options-gcc-mt-1_53.a include $(prebuilt_static_library)  # boost_chrono # include $(clear_vars) local_module := boost_chrono local_src_files := libboost_chrono-gcc-mt-1_53.a include $(prebuilt_static_library)

and module use of boost libraries looks this

local_path := $(call my-dir)  # signalserver, executable  # include $(clear_vars) local_cflags           := -dtixml_use_ticpp #local_cflags           += -ddebug local_static_libraries := boost_thread \     boost_system \     boost_filesystem \     boost_program_options \     boost_chrono \ local_static_libraries += ticpp \     tia \     tobicore \     tobiid \     tid \     gdf local_module           := signalserver local_c_includes       := $(local_path)/include local_c_includes       += $(local_path)/extern/include local_c_includes       += $(local_path)/../boost/include/boost-1_53 local_src_files        := #cpp source  include $(build_executable)

in addition have android.mk subdir makefiles listed

top_path := $(call my-dir)  include $(top_path)/boost/lib/boost.mk include $(top_path)/signalserver/signalserver.mk . .

and application.mk:

app_platform          := android-14 app_abi               := armeabi-v7a #app_optim             := debug #ndk_debug             := 1  ndk_toolchain_version := 4.6 app_stl               := gnustl_static app_cppflags          := -fexceptions -frtti

java.lang.NoClassDefFoundError When Creating New Android Project -

i've tried installing (and re-installing) android studio several times now, , each time, studio isn't able create new android project. when attempt initial android studio window (ie. basic 'create', 'open', 'import' etc options), i'm asked of questions in wizard, brief progress dialog, followed nothing @ all. if open incomplete project process creates choosing 'open' list, can try choosing create new android project menu. this has same issue, error message in output console time... java.lang.noclassdeffounderror: com/sun/xml/internal/bind/v2/model/annotation/annotationreader (wrong name: com/sun/xml/internal/bind/v0/model/qnnotation/annotationreader) note: when installed android studio, installed incompatible jdk (1.8, not 1.7). have had go default project settings change jdk uses 1.8. does know how can avoid this? there place should downloading jxb classes? missing in java paths? this appears have been caused cor

Decoding a Python 2 `tempfile` with python-future -

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
