无法在 Visual Studio 2010 下将 PhysFS 链接到我的 C++ 项目

【问题标题】：Can't link PhysFS into my C++ project under Visual Studio 2010无法在 Visual Studio 2010 下将 PhysFS 链接到我的 C++ 项目
【发布时间】：2012-01-07 13:47:23
【问题描述】：

我正在尝试在 Visual Studio 2010 下的 C++ 游戏中使用 PhysFS（使用 C++ wrapper），但链接器拒绝链接库。
我根据 INSTALL.txt 文件构建了库，并在 C:\include\physfs-2.0.2\lib\Debug 中有一个 physfs.lib，但它告诉我它找不到符号.但是，它肯定可以找到 .lib 文件，因为如果我更改库路径或库名称，它会引发错误。
我对此完全感到困惑，有人可以帮忙吗？这是我的设置：

VC++ 目录->库目录

C:\include\glew-1.7.0\lib
C:\include\boost_1_47_0\libs\
C:\include\glfw-2.7.2\lib
C:\include\glfw-2.7.2\lib\win32
C:\include\boost_1_47_0\stage\lib\
c:\include\allegro-5.0.5-msvc-10.0\lib
C:\include\physfs-2.0.2\lib\Debug
$(LibraryPath)

链接器->输入->附加依赖

physfs.lib
glew32d.lib
GLFW.lib
opengl32.lib
allegro-5.0.5-md-debug.lib
allegro_dialog-5.0.5-md-debug.lib
%(AdditionalDependencies)

    【解决方案1】：

    我最终（在其他人的一些指导下）发现问题在于 CMake 自动将 PhysFS 的构建定位到静态 win64 库，而我的项目期望它是共享的 win32 dll。
    我通过重新配置解决了静态/共享问题，但我找不到任何设置机器架构的东西。 （大概有什么，但我对 CMake 一无所知。）
    我的最终解决方案：

    1. 使用仅共享的选项进行干净的 CMake 配置。
    2. 在 Build->Configuration Manager 中添加 Win32 作为平台并禁用 test_physfs
    3. 在 phyfs 的 Project->Properties->Linker->Advanced 中，将 Target Machine 设置为 MachineX86。
    4. 在 Linker->Command Line 中，从 Additional Options 中删除 /MACHINE:X64（这个让我发疯，直到我通过机会）

    之后，它编译成一个完美链接的win32 dll。呜呜呜。

      【解决方案2】：

      根本问题是最顶部的警告

      LINK：警告 LNK4098：defaultlib 'MSVCRT' 与其他库的使用冲突；使用 /NODEFAULTLIB:library

      这里的编译器表示您的项目链接的所选 C 运行时库与您的部分/所有库选择的版本冲突。这显然导致它不使用标准库，并且您最终会遇到其中定义的类型的链接器错误流。

      您需要为所有库和该项目选择一个 C 运行时版本。然后针对它编译它们。
