Android原生C++项目中CMake无法链接.so文件的问题解决

我正在构建一个Android原生C++项目，想要引入名为general的共享库。文件布局如下：

• .so文件存放于jniLibs下对应${ANDROID_ABI}的子目录中
• 头文件存放在include/general目录下

我最初编写的CMake配置代码如下：

add_library(general SHARED IMPORTED)

set_target_properties(general PROPERTIES
        IMPORTED_LOCATION  "${CMAKE_CURRENT_SOURCE_DIR}/../jniLibs/${ANDROID_ABI}/libgeneral.so"
        )

include_directories(include/general)

...

target_link_libraries( # Specifies the target library.
        hello_cmale
        general
        ${log-lib}
        )

解决方案 #

general是CMake的保留关键字，直接使用会导致配置异常。只需将CMake文件中所有引用该库的名称替换为非关键字即可，比如改为general_lib，修改后的代码示例：

add_library(general_lib SHARED IMPORTED)

set_target_properties(general_lib PROPERTIES
        IMPORTED_LOCATION  "${CMAKE_CURRENT_SOURCE_DIR}/../jniLibs/${ANDROID_ABI}/libgeneral.so"
        )

include_directories(include/general)

...

target_link_libraries( # Specifies the target library.
        hello_cmale
        general_lib
        ${log-lib}
        )
