Question

我尝试将根app/文件链接到C ++项目，但始终收到此错误。

CMake Error at CMakeLists.txt:15 (add_library):


    src/main/cpp/iob.c


  Tried extensions .c .C .c++ .cc .cpp .cxx .m .M .mm .h .hh .h++ .hm .hpp


  .hxx .in .txx


CMake Error: CMake can not determine linker language for target: iob

我在CMakeLists.txt内有我的src/min/cpp文件以及它说找不到的iob.c文件。我在做什么错了？

这是我的CMakeLists.txt

# Sets the minimum version of CMake required to build your native library.
# This ensures that a certain set of CMake features is available to
# your build.

cmake_minimum_required(VERSION 3.4.1)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -Wall -Werror")

# Specifies a library name, specifies whether the library is STATIC or
# SHARED, and provides relative paths to the source code. You can
# define multiple libraries by adding multiple add.library() commands,
# and CMake builds them for you. When you build your app, Gradle
# automatically packages shared libraries with your APK.

add_library( # Specifies the name of the library.
         iob

         # Sets the library as a shared library.
         SHARED

         # Provides a relative path to your source file(s).
         src/main/cpp/iob.c )

Answer 1

如果CMakeLists.txt在src/main/cpp目录中（这是AS向导生成C ++项目的方式），那么您应该说

add_library( # Specifies the name of the library.
     iob

     # Sets the library as a shared library.
     SHARED

     # Provides a relative path to your source file(s).
     iob.c )

相对于CMakeLists.txt计算到源文件的相对路径。
