我正在尝试为android编译mpg123并将mp3文件解码为pcm samples.I已使用cmake将mpg123库添加到项目中。我的CMakeLists.txt文件如下所示：
cmake_minimum_required(VERSION 3.4.1)
set(
PATH_TO_MPG123
"src/native/mpg123_1.24.0/src"
"src/native/mpg123_1.24.0/src/libmpg123"
"src/native/mpg123_1.24.0/src/libout123"
"src/native/mpg123_1.24.0/src/compat" )
file(GLOB_RECURSE MPG123_SRC src/native/mpg123_1.24.0/src/libmpg123/*.c)
add_library(
native-mpg123
SHARED
${MPG123_SRC} )
include_directories(${PATH_TO_MPG123})
link_directories(${PATH_TO_MPG123})
add_executable(exe src/main/cpp/mpg123_decoder.cpp)
find_library(
log-lib
log )
target_link_libraries(
exe
native-mpg123
${log-lib} )
但我遇到了几个错误：
