遇到的 问题
官网首页提供的ceed工程缺少文件无法编译，就只能使用的主线版本的库 cegui-master 编译的
编译cegui-master库过程中遇到很多坑
###代码里用到了很多c++17的特性，而设置里默认是14，找到 cegui-master/cmake/CEGUIMacros.cmake 将CXX_STANDARD 改为17
CEGUIMacros.cmake
###########################################################################
# SHARED LIBRARY SET UP
###########################################################################
if (CEGUI_BUILD_DYNAMIC_CONFIGURATION)
add_library(${_LIB_NAME} ${_LIB_TYPE} ${${_SOURCE_FILES_VAR}} ${${_HEADER_FILES_VAR}})
set_target_properties(${_LIB_NAME} PROPERTIES DEFINE_SYMBOL ${_CEGUI_EXPORT_DEFINE})
set_target_properties(${_LIB_NAME} PROPERTIES
C_STANDARD 14
C_STANDARD_REQUIRED ON
CXX_STANDARD 17
CXX_STANDARD_REQUIRED ON
CXX_EXTENSIONS OFF)
cegui-master/application_templates/CMakeLists.txt 也需要添加c++17
在CMakeLists.txt 前面添加
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)
###删除noexcept，c++17 默认为noexcept
/home/cegui-master/cegui/src/text/RenderedText.cpp:49:1: error: function ‘CEGUI::RenderedText::RenderedText(CEGUI::RenderedText&&)’ defaulted on its redeclaration with an exception-specification that differs from the implicit exception-specification ‘’
将 RenderedText::RenderedText(RenderedText&&) noexcept = default
改为
RenderedText::RenderedText(RenderedText&&) default
搜索cegui中所有用到 noexcept 全部删掉
zxd@zxd-pc:~/Tools/zip/ceguizip/cegui-master/cegui/include/CEGUI$ grep -r “noexcept” .
./String.h: String(CEGUI::String&& other) noexcept
./String.h: String& operator=(String&& str) noexcept
./falagard/ImagerySection.h: ImagerySection(ImagerySection&& obj) noexcept = default;
./falagard/ImagerySection.h: ImagerySection& operator =(ImagerySection&& other) noexcept = default;
./falagard/WidgetLookFeel.h: WidgetLookFeel(WidgetLookFeel&& other) noexcept = default;
./falagard/WidgetLookFeel.h: WidgetLookFeel& operator =(WidgetLookFeel&& other) noexcept = default;
./Event.h: ScopedConnection(ScopedConnection&& other) noexcept : d_connection(std::move(other.d_connection)) {}
./Event.h: ScopedConnection(Event::Connection&& connection) noexcept : d_connection(std::move(connection)) {}
./Event.h: ScopedConnection& operator =(ScopedConnection&& other) noexcept
./text/RenderedText.h: //RenderedText(RenderedText&&) noexcept;
./text/RenderedText.h: //RenderedText& operator =(RenderedText&&) noexcept;
./Rectf.h: Rectf(Rectf&&) noexcept = default;
./Rectf.h: Rectf& operator =(Rectf&&) noexcept = default;
./Exceptions.h: virtual ~Exception() noexcept;
./Exceptions.h: const char* what() const noexcept override;
###然后又遇到缺少InputAggregator，查了一下发现使用inputAggregator的地方还不少，全是应用程序模板里面的，在Build里面找到CMakeCache.txt 把不用的模板全部关掉
反正编译master是为了编译ceed编辑器，用不了这些功能
zxd@zxd-pc:~/Tools/zip/ceguizip/cegui-master$ grep -r “CEGUI::InputAggregator” .
./application_templates/SFML2.cpp:static CEGUI::InputAggregator* G_inputAggregator;
./application_templates/SFML2.cpp: G_inputAggregator = new CEGUI::InputAggregator(G_context);
./application_templates/glfw3.cpp:static CEGUI::InputAggregator* G_inputAggregator;
./application_templates/SDL2.cpp:static CEGUI::InputAggregator* G_inputAggregator;
./application_templates/Ogre.cpp: CEGUI::InputAggregator* inputAggregator;
./application_templates/Ogre.cpp: app_pak.inputAggregator = new CEGUI::InputAggregator(app_pak.context);
./cegui/src/ScriptModules/SWIG/CEGUI.i:%feature(“notabstract”) CEGUI::InputAggregator;
./cegui/src/ScriptModules/SWIG/CEGUI.i:%extend CEGUI::InputAggregator {
zxd@zxd-pc:~/Tools/zip/ceguizip/cegui-master$ grep -r “InputAggregator”
application_templates/python-swig.py:inputAggregator = CEGUI.InputAggregator(context)
application_templates/SFML2.cpp:static CEGUI::InputAggregator* G_inputAggregator;
application_templates/SFML2.cpp: G_inputAggregator = new CEGUI::InputAggregator(G_context);
application_templates/glfw3.cpp:static CEGUI::InputAggregator* G_inputAggregator;
application_templates/glfw3.cpp: G_inputAggregator = new InputAggregator(G_ctx);
application_templates/SDL2.cpp:static CEGUI::InputAggregator* G_inputAggregator;
application_templates/SDL2.cpp: G_inputAggregator = new InputAggregator(G_context);
application_templates/Ogre.cpp: CEGUI::InputAggregator* inputAggregator;
application_templates/Ogre.cpp: app_pak.inputAggregator = new CEGUI::InputAggregator(app_pak.context);
cegui/src/ScriptModules/SWIG/CEGUI.i:%feature(“notabstract”) CEGUI::InputAggregator;
cegui/src/ScriptModules/SWIG/CEGUI.i:%include “CEGUI/InputAggregator.h”
cegui/src/ScriptModules/SWIG/CEGUI.i:%extend CEGUI::InputAggregator {
zxd@zxd-pc:~/Tools/zip/ceguizip/cegui-master$
//Specifies whether to build the application templates.
CEGUI_BUILD_APPLICATION_TEMPLATES:BOOL=ON
//Specifies whether to build the application template for GLFW3
CEGUI_BUILD_APPLICATION_TEMPLATE_GLFW3:BOOL=OFF
//Specifies whether to build the application template for OGRE
CEGUI_BUILD_APPLICATION_TEMPLATE_OGRE:BOOL=OFF
//Specifies whether to build the application template for SDL2
CEGUI_BUILD_APPLICATION_TEMPLATE_SDL2:BOOL=OFF
//Specifies whether to build the application template for SFML2
CEGUI_BUILD_APPLICATION_TEMPLATE_SFML2:BOOL=OFF
###设置debug标记，后面ceed工程要用到，将编译出来的so库文件Debug和Relesase区分开，后面加后缀_d
CMakeLists.txt 搜索CEGUI_BUILD_SUFFIX
if (WIN32 OR APPLE)
set (CEGUI_BUILD_SUFFIX “_d” CACHE STRING “String holding a suffix appended to the name of output binaries (under CMake build, only used for debug).”)
else()
set (CEGUI_BUILD_SUFFIX “_d” CACHE STRING “String holding a suffix appended to the name of output binaries (under CMake build, only used for debug).”)
endif()
不同版本库的存放位置
CMakeLists.txt 搜索 CMAKE_LIBRARY_OUTPUT_DIRECTORY_DEBUG
# set build output locations
if (WIN32)
set (CMAKE_LIBRARY_OUTPUT_DIRECTORY “${PROJECT_BINARY_DIR}/bin”)
else()
set (CMAKE_LIBRARY_OUTPUT_DIRECTORY “${PROJECT_BINARY_DIR}/lib”)
endif()
set (CMAKE_LIBRARY_OUTPUT_DIRECTORY_DEBUG “${CMAKE_LIBRARY_OUTPUT_DIRECTORY}/debug”)
set (CMAKE_LIBRARY_OUTPUT_DIRECTORY_RELEASE “${CMAKE_LIBRARY_OUTPUT_DIRECTORY}/release”)
set (CMAKE_LIBRARY_OUTPUT_DIRECTORY_MINSIZEREL ${CMAKE_LIBRARY_OUTPUT_DIRECTORY})
set (CMAKE_LIBRARY_OUTPUT_DIRECTORY_RELWITHDEBINFO ${CMAKE_LIBRARY_OUTPUT_DIRECTORY})
CMakeCache.txt
//Sets the configuration to build (Release, Debug, etc…)
CMAKE_BUILD_TYPE:STRING=Debug
//String holding a suffix appended to the name of output binaries
// (under CMake build, only used for debug).
CEGUI_BUILD_SUFFIX:STRING=_d
这样编译出来的debug 就存放在 build/bin/debug release存放在 build/bin/release
###编译完成后 sudo make install ，把so库文件安装在系统目录/usr/local/lib/cegui-9999.0/中
###然后是编译ceed项目，由于官网主页下载的1.1.2版本因为缺少文件，没有编译成功，只有使用github的 ceed-cpp-master 主线版
qt creator 打开项目工程
###也需要 c++17
打开 ceed-cpp.pro 设置 CONFIG
CONFIG += c++17
再添加这条，这样找依赖库就可以在ceed程序当前目录下找
unix:!macx:!liunx: QMAKE_RPATHDIR += $$PWD/
###提示找不到std::squrt ，添加头文件 #include<math.h>,然后把std::去掉
然后下面有两个地方可能需要改
bool toActualValue(ValueTypeStore& actualValue, BaseValueType baseValue) const override
{
// Z axis goes through the screen, 2D objects are rotated around it
#ifdef GLM_FORCE_RADIANS
actualValue = glm::angleAxis(glm::radians(normalizeAngle(baseValue)), 0.f, 0.f, 1.f);
#else
actualValue = glm::angleAxis(normalizeAngle(baseValue), glm::vec3(0.f, 0.f, 1.f));
#endif
return true;
}
// if resort is True the children are sorted according to their order in CEGUI::Window
void WidgetHierarchyItem::refreshOrderingData(bool resort, bool recursive)
{
// resort=True with recursive=False makes no sense and is a bug
assert(!resort || recursive);
if (!_manipulator || !_manipulator->getWidget()) return;
QVariant var;
var.setValue(_manipulator->getWidgetIndexInParent())
setData(var, Qt::UserRole + 1);
然后就可以执行调试了看到编辑器主界面了，但是还不能用
将cegui-master/build/lib/debug目录下这些文件复制到 build-ceed-cpp-gcc-Debug/bin
然后新建一个空工程文件夹 testpro
然后在把文件夹 /usr/local/share/cegui-9999 复制到工程 testpro 改名字为resource
这个时候应该就能够正常使用了
