How to resolve error: no suitable linker for object.{cxx cc}?

[nekomiya-kasane]

Hello, I want to export this project to vs2022's sln project but failed with error: no suitable linker for object.{cxx cc} Is there any way to resolve the error? xmake.lua shown below. Some dirs are replaced with d1/d2....

target("InternalHeaders") do
    set_kind("headeronly")

    add_includedirs("d1", {interface = true})
    add_includedirs("d2", {interface = true})
    add_includedirs("d3", {interface = true})
    add_includedirs("d4", {interface = true})
    add_includedirs("d5", {interface = true})
    add_includedirs("d6", {interface = true})
end

target("obj") do
    set_kind("object")
    add_defines("EXPORTS")

    if not is_plat("windows") then
        add_cxxflags("-fPIC")
    end

    add_extern("jsoncpp", {public = true})
    add_extern("eigen", {public = true})
    --add_packages("jsoncpp", "eigen", {public = true})

    add_deps("InternalHeaders")

    add_files("d1/**.cpp")
    add_files("d2/**.cpp")
    add_files("d3/**.cpp")
    add_files("d4/**.cpp")
    add_files("d5/**.cpp")
    add_files("d6/**.cpp")
    add_files("d7/**.cpp")
end

object kind is not supported for vs generator now.

[nekomiya-kasane]

will it be supported in the near future?

[waruqi]

This could take a lot of time to support, so I probably won't be considering it anytime soon. You may also open a feature request first.

or you can use vsxmake project generator. it is supported for vsxmake.

Thanks for your reply.

I tried vsxmake, but I got another error

xmake project vsxmake
checking for Microsoft Visual Studio (x64) version ... 2022
checking for Microsoft C/C++ Compiler (x64) version ... 19.36.32532
checking for is_clang ... no
checking for is_unix ... no
checking for pointer-size ... 8
checking for is_msvc ... ok
error: no suitable linker for headeronly.{}

So is headeronly not supported for vsxmake? If so, It seems I cannot export my project to sln now...
Will this be supported in the near future, or are there any workarounds?

[waruqi]

right, headeronly is not supported, why do you want to use it?

you can use function to add them

function add_InternalHeaders()
    add_includedirs("d1", {interface = true})
    add_includedirs("d2", {interface = true})
    add_includedirs("d3", {interface = true})
    add_includedirs("d4", {interface = true})
    add_includedirs("d5", {interface = true})
    add_includedirs("d6", {interface = true})
end

target("obj") do
    set_kind("object")
    add_defines("EXPORTS")

    if not is_plat("windows") then
        add_cxxflags("-fPIC")
    end

    add_extern("jsoncpp", {public = true})
    add_extern("eigen", {public = true})
    --add_packages("jsoncpp", "eigen", {public = true})

    add_InternalHeaders()

    add_files("d1/**.cpp")
    add_files("d2/**.cpp")
    add_files("d3/**.cpp")
    add_files("d4/**.cpp")
    add_files("d5/**.cpp")
    add_files("d6/**.cpp")
    add_files("d7/**.cpp")
end
