我正在尝试从 John McCucatchan github [ 1 ] 编译 Bullet 演示，但没有成功。此存储库中的预制文件设置为仅构建 NaClAMBullet 和 NaClAMTest。所以我修改了 premake64.lua 以针对 NaClAMBullet 而不是 NaClAMTest。但它没有用。

local nacl_sdk_path = os.getenv("NACL_SDK_ROOT")
local nacl_toolchain_path = os.getenv("NACL_SDK_BIN")
local bullet_path = os.getenv("BULLET_ROOT")
premake.gcc.cc  = nacl_toolchain_path .. "/x86_64-nacl-gcc"
premake.gcc.cxx = nacl_toolchain_path .. "/x86_64-nacl-g++"
premake.gcc.ar  = nacl_toolchain_path .. "/x86_64-nacl-ar"

solution "NaClAM"
    configurations { "Debug", "Release" }

project "NaClAMBase64"
    kind "StaticLib"
    language "C++"
    files { 
        "NaClAMBase/*.cpp",
        }
    includedirs { nacl_sdk_path .. "/include" }
    configuration "Debug"
        defines { "DEBUG" }
        flags { "Symbols" }
        targetdir "premake/lib/debug"
        buildoptions { "-std=gnu++0x -fno-rtti -fno-exceptions -m64 -msse2" }
    configuration "Release"
        defines {"NDEBUG"}
        flags {"Optimize"}
        targetdir "premake/lib/release"
        buildoptions { "-std=gnu++0x -fno-rtti -fno-exceptions -m64 -msse2" }

project "NaClAMBullet64"
    kind "ConsoleApp"
    language "C++"
    files {
        "NaClAMBullet/*.cpp",
        }
    includedirs { "." }
    includedirs { bullet_path }
    includedirs { "/include" }
    includedirs { nacl_sdk_path .. "/include" }
    links { "NaClAMBase64", "m", "pthread", "ppapi" }
    configuration "Debug"
        defines { "DEBUG" }
        flags { "Symbols" }
        targetdir "premake/bin/debug"
        targetextension ".nexe"
        buildoptions { "-std=gnu++0x -fno-rtti -fno-exceptions -m64 -msse2" }
    configuration "Release"
        defines {"NDEBUG"}
        flags {"Optimize"}
        targetdir "premake/bin/release"
        targetextension ".nexe"
        buildoptions { "-std=gnu++0x -fno-rtti -fno-exceptions -m64 -msse2" }

要构建 Makefile，我只需运行以下行：

premake4 --file=premake64.lua gmake

要构建应用程序，只需键入：

make -R

这些操作的结果是以下编译错误：

我究竟做错了什么？这些依赖关系问题是否需要在 premake 文件或其他地方解决？

如果认为这是一个与 Premake 无关的构建问题：编译器无法决定它应该使用哪个版本的 Json::Value 构造函数。
