Android NDK Cmake链接.a(静态)库 [英] Android NDK Cmake Linking .a (Static) Libs
问题描述
我将Android Studio 2.2.2与cmake和Android NDK结合使用.我在链接.a库(静态库)时遇到问题.
I am using Android Studio 2.2.2 with cmake and Android NDK. I have a problem linking .a library (Static lib).
这是我的cmake:
# Sets the minimum version of CMake required to build the native
# library. You should either keep the default value or only pass a
# value of 3.4.0 or lower.
cmake_minimum_required(VERSION 3.4.1)
set(CMAKE_VERBOSE_MAKEFILE on)
# Creates and names a library, sets it as either STATIC
# or SHARED, and provides the relative paths to its source code.
# You can define multiple libraries, and CMake builds it for you.
# Gradle automatically packages shared libraries with your APK.
add_library(lib_webp SHARED IMPORTED )
set_target_properties(lib_webp PROPERTIES IMPORTED_LOCATION
src/main/jni/${ANDROID_ABI}/libwebp.so)
add_library( # Sets the name of the library.
game-lib
# Sets the library as a shared library.
SHARED
# Provides a relative path to your source file(s).
# Associated headers in the same location as their source
# file are automatically included.
src/main/cpp/main.cpp
src/main/cpp/android_native_app_glue.c
)
target_include_directories(game-lib PRIVATE
../../../../libs/headers/android
)
include_directories($ENV{NDK_MODULE_PATH}/sources/android/native_app_glue/)
# Specifies libraries CMake should link to your target library. You
# can link multiple libraries, such as libraries you define in the
# build script, prebuilt third-party libraries, or system libraries.
target_link_libraries( # Specifies the target library.
game-lib
# Links the target library to the log library
# included in the NDK.
# ${log-lib}
# Specifies the name of the NDK library that
# you want CMake to locate.
log
android
OpenSLES
z
GLESv2
EGL
dl
)
add_definitions(-g -DANDROID -Wno-write-strings -fsigned-char -Wno-conversion-null)
TARGET_LINK_LIBRARIES(game-lib libtheoraplayer.a)
我的链接器报告错误
arm-linux-androideabi/bin \ ld:错误:找不到-ltheoraplayer
arm-linux-androideabi/bin\ld: error: cannot find -ltheoraplayer
错误:对'TheoraVideoManager :: TheoraVideoManager(int)'的未定义引用
error: undefined reference to 'TheoraVideoManager::TheoraVideoManager(int)'
这是libtheoraplayer.a的一部分.有人遇到过类似的问题吗?知道如何解决这个问题吗?
which is a part of libtheoraplayer.a. Did anyone had similar problem? Any idea how to solve this?
我在该位置上有静态库libtheoraplayer.a.我什至也有共享库libtheoraplayer.so,但是我也无法链接它.
I have the Static lib libtheoraplayer.a present at that location. I even have the Shared lib also, libtheoraplayer.so but I can`t link it either.
任何建议将不胜感激.
干杯.
推荐答案
发布答案.正如Tsyvarev所说,库的非绝对文件名存在问题.当我使用绝对路径时,它就像一种魅力.
To post the answer. As Tsyvarev said, the problem with non-absolute file name for library. When I used absoulte path it worked like a charm.
谢谢. 干杯.
