Linking static library fails with Premake5

I'm using Premake5 as the build system for a C++ project, which currently consists of a static library (Core) and a console application (Tests). However, when I attempt to compile Tests including files from Core, the compiler produces the following error:

I'm using the Jarod cmake module, which is why the error involves CMake.

Using the default gmak2 gives the following error:

The current premake file content is the following:

workspace "Chess"
    configurations { "Debug", "Release" }

    cppdialect "C++17"

    location ".premake/generated/"
    bindirs ".premake/build/%{cfg.buildcfg}/bin/%{prj.name}"
    objdir ".premake/build/%{cfg.buildcfg}/obj/%{prj.name}"

    project "Core"
        kind "StaticLib"
        language "C++"
        
        files { "src/core/**.hpp", "src/core/**.cpp" }
        includedirs { "src/core", "src/core/**" }

        filter "configurations:Debug"
            defines { "DEBUG" }
            symbols "On"
        filter "configurations:Release"
            defines { "NDEBUG" }
            optimize "On"
        filter ""

    project "Tests"
        kind "ConsoleApp"
        language "C++"

        files {
            "tests/unit/**.cpp",
            "tests/MainTest.cpp",
            "tests/vendor/gtest/**.h",
            "tests/vendor/gtest/src/*.cc"
        }
        includedirs {
            "tests/vendor/gtest/",
            "tests/vendor/gtest/include/"
        }
        links { "Core" }

        filter "configurations:Debug"
            defines { "DEBUG" }
            symbols "On"

I expected this configuration to correctly set up the include paths and link the Core library with the Tests application. What might be causing this issue, and how can I resolve it?

Solution

  • You forget to add proper includedirs in "Tests" (links does propagate includedirs):

    project "Tests"
-- ...
        includedirs {
            "tests/vendor/gtest/",
            "tests/vendor/gtest/include/",
            "src/core", "src/core/**"
        }
