Xmake 版本

v2.9.1+HEAD.0c79f6162

操作系统版本和架构

Windows 8.1

描述问题

我的xmake.lua如下

add_rules("mode.debug", "mode.release")

if is_mode("debug") then
    add_defines("DEBUG")
    set_symbols("debug")
    set_warnings("all")
elseif is_mode("release") then
    set_strip("all")
end

if not is_os("windows") then
    add_syslinks("m")
end

target("objs")
    set_kind("object")
    set_warnings("all")
    add_includedirs("include", {public = true})
    add_files("src/*.c")
    add_cflags("-fPIC")

target("radicalite_static")
    set_kind("static")
    set_warnings("all")
    add_deps("objs")
    set_basename("radical")
    set_prefixname("lib")

target("radicalite_shared")
    set_kind("shared")
    set_warnings("all")
    add_deps("objs")
    set_basename("radical")
    set_prefixname("lib")

target("headers")
    set_kind("headeronly")
    add_headerfiles("include/(*.h)") 

target("eyyc")
    set_kind("binary")
    add_files("examples/eyyc.c")
    set_default(false)
    set_warnings("all")
    add_deps("radicalite_shared")
    add_rpathdirs(".")
    add_rpathdirs("/usr/lib")
    add_rpathdirs("/usr/local/lib")
    add_rpathdirs("@executable_path")

执行后部分输出如下：

collect2.exe: error: ld returned 1 exit status
error: execv(D:\mingw64\bin\x86_64-w64-mingw32-g++ -o build\windows\x64\debug\eyyc.exe build\.objs\eyyc\windows\x64\debug\examples\eyyc.c.obj -Wl,-rpath=. -Wl,-rpath=\usr\lib -Wl,-rpath=\usr\local\lib -Wl,-rpath=$ORIGIN -g) failed(1)

在 target("eyyc") 中有 add_deps("radicalite_shared") 继承动态库依赖，然而生成的编译命令中并没有-L和-l，linker也不会链接这个库，导致链接失败。

在v2.7.5版本中似乎没有此问题。

期待的结果

linker能够链接通过add_deps依赖的动态库

他说的可能是这种情况:

-- xmake.lua
target('foo', function()
  set_kind('object')
  add_files('foo.c')

  before_build(function(T)
    io.writefile(
      'foo.c',
      [[
void foo() {}
]]
    )
  end)
end)

target('shared', function()
  set_kind('shared')

  add_deps('foo')
end)

target('add_deps', function()
  set_kind('binary')
  add_files('main.c')

  add_deps('shared')

  before_build(function(T)
    io.writefile(
      'main.c',
      [[
extern void foo();

int main() {
  foo();

链接 add_deps 时没有 -lshared flag.
