Question

在更改为CMake和Travis CI构建环境时，我启用了Travis CI上的编译。即使CMake项目在我的电脑上正确编译，Travis还是退出了2：

In file included from /home/travis/build/Codestones/Proton/source/application.cpp:1:0:
/home/travis/build/Codestones/Proton/source/application.h:3:23: fatal error: glad\glad.h: No such file or directory
 #include <glad\glad.h>
                       ^
compilation terminated.
make[2]: *** [CMakeFiles/Proton.dir/source/application.cpp.o] Error 1
make[1]: *** [CMakeFiles/Proton.dir/all] Error 2
make: *** [all] Error 2

这是我的CMakeLists.txt：

cmake_minimum_required(VERSION 3.1)

project(Proton)

set(CMAKE_CXX_STANDARD 11)

set_property(GLOBAL PROPERTY USE_FOLDERS ON)

set(SRC_DIR "${CMAKE_CURRENT_SOURCE_DIR}/source")
set(LIB_DIR "${CMAKE_CURRENT_SOURCE_DIR}/dependencies")

# Executable definition and properties
file(GLOB SOURCES
    "${SRC_DIR}/*.h"
    "${SRC_DIR}/*.cpp"
)
add_executable(Proton "${SOURCES}")

# GLFW
set(GLFW_DIR "${LIB_DIR}/glfw")
set(GLFW_BUILD_EXAMPLES OFF CACHE INTERNAL "Build the GLFW example programs")
set(GLFW_BUILD_TESTS OFF CACHE INTERNAL "Build the GLFW test programs")
set(GLFW_BUILD_DOCS OFF CACHE INTERNAL "Build the GLFW documentation")
set(GLFW_INSTALL OFF CACHE INTERNAL "Generate installation target")
add_subdirectory("${GLFW_DIR}")
target_link_libraries(${PROJECT_NAME} "glfw" "${GLFW_LIBRARIES}")
target_include_directories(${PROJECT_NAME} PRIVATE "${GLFW_DIR}/include")
target_compile_definitions(${PROJECT_NAME} PRIVATE "GLFW_INCLUDE_NONE")

# GLAD
set(GLAD_DIR "${LIB_DIR}/glad")
add_subdirectory("${GLAD_DIR}")
target_link_libraries(${PROJECT_NAME} "glad" "${GLAD_LIBRARIES}")
target_include_directories(${PROJECT_NAME} PRIVATE "${PROJECT_BINARY_DIR}/dependencies/glad/include")

我认为这意味着glad.h缺失或链接不正确，但为什么它会在我的电脑上构建并运行良好？

Answer 1

\不能在#include指令中用作路径分隔符，请使用/。如果你的本地（Windows？）编译器理解它，它是一个非可移植的扩展。

Answer 2

gcc支持Windows上包含路径中的反斜杠作为扩展名

#include <glad\glad.h>

在linux下不支持此功能，您只应在包含路径

中使用正斜杠/

#include <glad/glad.h>

本地构建工作正常时没有这样的文件或目录
