My application requires Android keyboard. I’ve got LatinIME from AOSP and made gradle module. LatinIME support Android Accessibility and works perfect with TalkBack. Here is screenshots: Here is link for my github repo:
When I built native library for LatinIME I’ve got next error: undefined reference to ‘__atomic_exchange_4 Full stacktrace:
1 2 3 4 5 6 | /Volumes/Android/buildbot/src/android/ndk-r13-release/external/libcxx/include/memory:635: error: undefined reference to '__atomic_load_4' /Volumes/Android/buildbot/src/android/ndk-r13-release/external/libcxx/../../external/libcxxabi/src/cxa_handlers.cpp:112: error: undefined reference to '__atomic_exchange_4' /Volumes/Android/buildbot/src/android/ndk-r13-release/external/libcxx/../../external/libcxxabi/src/cxa_default_handlers.cpp:106: error: undefined reference to '__atomic_exchange_4' /Volumes/Android/buildbot/src/android/ndk-r13-release/external/libcxx/../../external/libcxxabi/src/cxa_default_handlers.cpp:117: error: undefined reference to '__atomic_exchange_4' clang++: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [obj/local/armeabi/libjni_latinime.so] Error 1 |
To avoid it open Android.mk file and add next string:
1 | LOCAL_EXPORT_LDLIBS += -latomic |
I working on LatinIME Android Keyboard keyboard. I’ve got source from Google repo. Here is structure: java – contains java code native – jni code. When I try to build native I receive next error:
