Linking errors when running project with specific configuration

问题

我当前在使用Premake5.lua运行我的项目时遇到了链接错误的问题，特定配置下会出现问题。以下是我Premake5.lua文件中的相关配置：

files { "src/**.cpp", "src/**.hpp" }

但是，当我将配置更改为以下内容时，一切似乎正常运行：

files { "**.cpp", "**.hpp" }

是否有人能解释为什么会发生这种情况，以及如何解决这个问题？

这是完整的配置代码：

  2. -- 包括Conan生成脚本
  3. include("conanbuildinfo.premake.lua")
  4. -- 清理工作区的脚本
  5. include("cleanWorkspace.lua")
  7. -- 主工作区
  8. workspace "ImageEditor"
  9.     -- 导入Conan生成配置
  10.     conan_basic_setup()
  12.     -- 项目
  13.     project "ImageEditorApp"
  14.         kind "ConsoleApp"
  15.         language "C++"
  16.         targetdir "bin/%{cfg.buildcfg}"
  17. 		objdir "bin/%{cfg.buildcfg}/obj/"
  18. 		location "src"
  19.         debugdir "app"
  21.         linkoptions { conan_exelinkflags }
  23.         files { "src/**.cpp", "src/**.hpp" }
  24.         includedirs { "./bindings" }
  26.         filter "configurations:Debug"
  27. 		defines { "DEBUG" }
  28. 		symbols "On"
  30. 		filter "configurations:Release"
  31. 		defines { "NDEBUG" }
  32. 		optimize "On"
  34.      -- 测试
  35.     project "ImageEditorTest"
  36.         kind "ConsoleApp"
  37.         language "C++"
  38.         targetdir "bin/%{cfg.buildcfg}"
  39.         objdir "bin/%{cfg.buildcfg}/obj/"
  40.         location "tests"
  41.         debugdir "app"
  42.         linkoptions { conan_exelinkflags }
  43.         links { "ImageEditor" }
  44.     
  45.         -- 添加测试文件
  46.         files { "tests/*.cpp" }
  47.         includedirs { "./src","./bindings" }
  49.         -- 也可以通过定义来配置Catch
  50. 	    defines "CATCH_CPP11_OR_GREATER"
  52.         filter "configurations:Debug"
  53.             defines { "DEBUG" }
  54.             symbols "On"
  56.         filter "configurations:Release"
  57.             defines { "NDEBUG" }
  58.             optimize "On"

我是新手，如果有人能提供关于如何管理项目并为其创建单元测试的信息，我将不胜感激。谢谢。

I am currently facing an issue with linking errors when running my project using Premake5.lua with a specific configuration.

Here is the relevant configuration in my Premake5.lua file:

files { &quot;src/**.cpp&quot;, &quot;src/**.hpp&quot; }

However, everything seems to work fine when I change the configuration to:

files { &quot;**.cpp&quot;, &quot;**.hpp&quot; }

Can anyone explain why this is happening and how I can resolve this issue?

Here is the full configuration code:

I new to these and if someone can provide info how this setup should look for managing project and create unit tests for it i would aprritate it . Thanks.

These are the errors i get:

答案1

得分: 1

  1. files { "src/**.cpp", "src/**.hpp" }

仅添加来自src目录的cpp文件和头文件。

  1. files { "**.cpp", "**.hpp" }

另外添加：

  • 来自"bindings"目录的文件（预期的文件）
  • 来自"tests"目录的文件（你不想要的文件）
  1. includedirs { "./bindings" }

不是添加来自该目录的文件，而是允许#include在该目录中搜索。

因此，你应该有：

  1. files { "src/**.cpp", "src/**.hpp" }
  2. files { "bindings/**.cpp", "bindings/**.hpp" }

或者单行写为

  1. files { "src/**.cpp", "src/**.hpp", "bindings/**.cpp", "bindings/**.hpp" }

  3. <summary>英文:</summary>

files { "src/.cpp", "src/.hpp" }

  2. adds only cpp files and header files from src directory.

files { ".cpp", ".hpp" }

  1. add in addition
  2. - files from &quot;bindings&quot; (the ones you expect)
  3. - files from &quot;tests&quot; (that you don&#39;t want)

includedirs { "./bindings" }

  2. is not to add files from that directory, but to allow `#include` to search on that directory.
  3. So you should have

files { "src/.cpp", "src/.hpp" }
files { "bindings/.cpp", "bindings/.hpp" }

  1. or in single line

files { "src/.cpp", "src/.hpp", "bindings/.cpp", "bindings/.hpp" }
