Question

我在Clion遇到了一个烦人的问题，就是我的项目总是有标题错误这是我的CmakeLists.txt：

cmake_minimum_required(VERSION 3.6)
project(geometry)

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

set(PROJECT_SOURCE_DIR geo)
set(CMAKE_INCLUDE_CURRENT_DIR geo)
include_directories("${PROJECT_BINARY_DIR}")
include_directories(${CMAKE_BINARY_DIR}/geo/)

set(SOURCE_FILES

    geo/Circle.cpp
    geo/Circle.h
    geo/geo.h
    geo/ICircle.cpp
    geo/ICircle.h
    geo/IPoint.cpp
    geo/IPoint.h
    geo/IRectangle.cpp
    geo/IRectangle.h
    geo/IShape.cpp
    geo/IShape.h
    geo/IText.cpp
    geo/IText.h
    geo/Point.cpp
    geo/Point.h
    geo/Rectangle.cpp
    geo/Rectangle.h
    geo/Shape.cpp
    geo/Shape.h
    geo/Text.cpp
    geo/Text.h
    owl/IThing.cpp

    rdfs/IResource.h
    rdfs/rdfs.h
    rdfs/Resource.cpp
    rdfs/Resource.h
    AllInOne.cpp
    example.cpp
    geometry.owl)

add_executable(geometry ${SOURCE_FILES})

这是example.cpp，它也是主要的cpp：

#include <autordf/Factory.h>

#include <geo/geo.h>

using namespace geo;


int main(int argc, char ** argv) {
    autordf::Factory f;
    f.addNamespacePrefix("geo", "http://example.org/geometry#");
    autordf::Object::setFactory(&f);

    geo::Rectangle r("http://example.org/myfancyrectangle");

    // Set one of my rectangle coordinates - the long way
    geo::Point tl;
    tl.setX(1.0);
    tl.setY(2.0);
    r.setTopLeft(tl);

    // Set one of my rectangle coordinates - the short way
    r.setBottomRight(geo::Point().setX(11).setY(12));

    // Set result of my work
    f.saveToFile(stdout, "turtle");
}

它在终端中完美运行但在Clion中的结果是：

geo/中的一个标头文件（例如Circle.cpp）如下所示：

/** @cond internal */
#include <geo/Circle.h>

// This is auto generated code by AutoRDF, do not edit !

namespace geo {

Circle::Circle(const std::string& iri) : autordf::Object(iri, ICircle::TYPEIRI) {
}

Circle::Circle(const Object& other) : autordf::Object(other) {
}

std::vector<Circle> Circle::find() {
    return findHelper<Circle>(ICircle::TYPEIRI);
}

}

/** @endcond internal */

所以，问题是我不能在头文件中包含其他头文件。如您所见，错误将是：

/home/burning/projects/autordf_projects/geometry/geo/Circle.cpp:2:24: fatal error: geo/Circle.h: No such file or directory
 #include <geo/Circle.h>
                        ^
compilation terminated.

有人可以帮我吗？

Answer 1

如评论中所述，您应该使用：

include_directories("${PROJECT_SOURCE_DIR}")

而不是：

include_directories("${PROJECT_BINARY_DIR}")

从PROJECT_SOURCE_DIR的文档中我们得到了：

当前项目的顶级源目录。

从PROJECT_BINARY_DIR的文档中我们得到了：

为项目构建目录的完整路径。

因此，除非您允许项目的源代码构建，否则您可能希望将源目录用作包含目录，不构建目录。
