【问题描述】:
我的问题是 CMake 拒绝编译并给出以下错误:
[orpheus@Poseidon build]$ make
sources : /home/orpheus/Projects/Personal/C++/test/testProj/src/helloworld/MyClass.cpp/home/orpheus/Projects/Personal/C++/test/testProj/src/helloworld.cpp
headers : /home/orpheus/Projects/Personal/C++/test/testProj/include/helloworld/MyClass.hpp

^
compilation terminated.

make: *** [Makefile:84: all] Error 2
我对 CMake 比较陌生,并且已经阅读了我能找到的大部分教程以及我能找到的所有相关堆栈溢出问题,但是似乎没有什么能完全满足我的特殊需求,我做到了(在我的调整中)偶然发现了一种没有发生这种情况的方式(不幸的是我现在无法复制它),但是这给了我一个链接错误声称:
c++; fatal error: no input files
我应该使用include_directory() 命令而不是set() 添加头文件吗?
我决定不使用glob() 根据CMake documentation 添加源的方法,我的解决方案基于this thread 和各种教程。
我的项目结构如下:
test/
|
+--CMakeLists.txt
+--build/
| |----CMakeFiles/
| |----etc
|
+--testProj/
| +----CMakeLists.txt
| +----include
| | +----CMakeLists.txt
| | +----helloworld/
| | | +----CMakeLists.txt
| | | +----MyClass.hpp
| |
| |----src
| | +----helloworld.cpp
| | +----CMakeLists.txt
| | +----helloworld/
| | | +----CMakeLists.txt
| | | +----MyClass.cpp
文件如下:
测试/CMakeFiles.txt
cmake_minimum_required(VERSION 3.6.1)
project(TEST)
add_subdirectory(testProj)
add_executable(${CMAKE_PROJECT_NAME} ${sources} ${headers})
set_target_properties(${CMAKE_PROJECT_NAME} PROPERTIES LINKER_LANGUAGE CXX)
set(extraFlags "-Wall -Wextra -Weffc++ -pedantic -pedantic-errors -std=c++14")
set(CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS} ${extraFlags})
test/testProj/CMakeLists.txt
include_directories(include)
add_subdirectory(src)
add_subdirectory(include)
set(sources ${sources} PARENT_SCOPE)
set(headers ${headers} PARENT_SCOPE)
test/testProj/include/CMakeLists.txt
include_directories(helloworld)
add_subdirectory(helloworld)
set(headers ${headers} PARENT_SCOPE)
test/testProj/include/helloworld/CMakeLists.txt
set(
headers
${headers}
${CMAKE_CURRENT_SOURCE_DIR}/MyClass.hpp
PARENT_SCOPE
)
test/testProj/src/CMakeLists.txt
add_subdirectory(helloworld)
set(
sources
${sources}
${CMAKE_CURRENT_SOURCE_DIR}/helloworld.cpp
PARENT_SCOPE
)
test/testProj/src/helloworld/CMakeLists.txt
set(
sources
${sources}
${CMAKE_CURRENT_SOURCE_DIR}/MyClass.cpp
PARENT_SCOPE
)
当我将头穿过显示器时,请有人指出我正确的方向。
