一些问题,并且大佬什么时候能更新一下文档

[smile-zyk]

1. demo中的#include <UGM/UGM.h>应该改为#include <UGM/UGM.hpp>
2. C++17 并不支持concept,应改为C++20
3. 使用MinGw11.2.0在CMake时会报一个奇怪的错误,具体为:

[build] D:\QT\Tools\mingw1120_64\bin\g++.exe  -IE:/lib/Ubpa/UCMake_0_6_4/include -isystem E:/lib/Ubpa/UGM_0_7_6/include -isystem E:/lib/Ubpa/UTemplate_0_7_2/include -g /fp:fast /permissive- /wd4201 -std=gnu++20 -MD -MT CMakeFiles/demo.dir/main.cpp.obj -MF CMakeFiles\demo.dir\main.cpp.obj.d -o CMakeFiles/demo.dir/main.cpp.obj -c E:/repos/Pipeline/main.cpp
[build] g++.exe: fatal error: cannot specify '-o' with '-c', '-S' or '-E' with multiple files

这里我使用的是Ninja,但是实际上使用MinGw Makefiles也会报同样的错误,原因貌似是出现了同名文件?我是直接用CMakeLists.txt构建的,每次一build就出现这个问题. MSVC 2019可以正常构建

---

虽然我非常感激大佬的工作,但是!!!! 折腾了一晚上却只是因为readme.md和setup.md没有及时更新而导致的. 我觉得非常难过,如果不能及时更新readme的话,起码要说明一下哪个版本可以在文档的指导下正常使用吧 按照现在的文档,连最简单的demo都跑不出,这真的好吗!!!!

demo 已更新 e6e73fa 主要是 demo 是工程外部的，所以没去测试到，然后就忘了有这回事。。。

对于问题 3，不清楚 不过这么简单的cmake例子，不大可能出错 从你发的 log 也看不大出问题

好的,非常感谢大佬! 关于问题三,我刚刚又尝试了一下. 我使用的是MinGw 11.2.0,CMake版本是3.21.1,操作系统是win10. 在demo文件夹内,使用Git Bash运行cmake时指定编译套件为"MinGw Makefiles".

具体的错误步骤是在这一步

D:\QT\Tools\mingw1120_64\bin\g++.exe  @CMakeFiles/demo.dir/includes_CXX.rsp /fp:fast /permissive- /wd4201 -std=gnu++20 -MD -MT CMakeFiles/demo.dir/main.cpp.obj -MF CMakeFiles\demo.dir\main.cpp.obj.d -o CMakeFiles\demo.dir\main.cpp.obj -c E:\lib\UGM\demo\main.cpp

并且经过我另开项目的反复测试,只要在项目的CMakeLists.txt中添加

find_package(UGM REQUIRED)

add_executable(XXX main.cpp)

target_link_libraries(XXX PUBLIC Ubpa::UGM_core)

不管是否真的引用了UGM中的内容,都会报与上面相同的错误. 当然上面的错误仅在使用了-G MinGw Makefiles与-G Ninja(只测试了这两个)才会出现,在windows系统中默认的cmake构建套件是MSVC compiler 并不会出现这些错误.
