5 years ago You need to put libicuuc.a after libboost_locale in your linker command line, currently it's used before libboost_locale, and since it's a static library, any symbol that is not referenced from anywhere else is discarded by the linker. Move add_library(libicuuc) command in your CMakeLists.txt below the place where you are defining Boost libraries.

I added these two libraries in my CMakeLists.txt file:
add_library( libiconv SHARED IMPORTED)
set_target_properties(libiconv PROPERTIES IMPORTED_LOCATION ${MY_ICONV_LIBS_DIR}/${ANDROID_ABI}/libiconv.so )
-----------------------------------------
add_library( libicuuc STATIC IMPORTED)
set_target_properties(libicuuc PROPERTIES IMPORTED_LOCATION ${MY_ICONV_LIBS_DIR}/${ANDROID_ABI}/libicuuc.a )
-----------------------------------------
I also used
android { ... sourceSets { main { // Android Studio doesn't package precompiled external (.so) libs into apk, even if linked against via "add_library (... SHARED IMPORTED) in CMakeLists.txt // See eg https://stackoverflow.com/questions/24357687/how-to-include-so-library-in-android-studio/29234765 // Hopefully this will be remedied in near future. // As a workaroun in the meantime, need to add them manually to jniLibs.srcDirs // Note: This causes ALL .so files in ABI (eg "armeabi-v7a") subdir of this dir to get packaged into .apk - relative to "app" dir // If you want to just include those necessary (eh chrono,, system) copy/link them to a separate dir, and reference that dir here instead. jniLibs.srcDirs = [ // should contain any external libs which should be compiled in {armeabi-v7a,arm64-v8a,x86,x86_64,mips} subdirs my_boost_dir_libs, my_iconv_dir_lib //, "src/main/JniLibs/boost" // could add additional dirs (with ABI subdirs) to be packaged into apk like this. // Relative paths like this will be interpreted as relative to "app" dir ] }
}}
Is there something else I need to do in order to link these libraries?
