应用错误收集

（为什么我要尝试这样做：我没有运气在Windows上使用libpng预先构建的二进制文件（尽管经过了数小时的试验和错误），因此我现在正在尝试自己编译它。我找到了this helpful blog post有关此问题，请填写Microsoft Visual Studio 2008项目文件，但遗憾的是仍然无法使用它。）

在链接到找到here的zlib二进制文件时成功编译，但在尝试将其链接到测试文件时，我会收到以下信息：

    C:\Documents and Settings\Administrator\My Documents>cl "C:\Documents and Settin
    gs\Administrator\My Documents\test.c" "C:\Documents and Settings\Administrator\M
    y Documents\libpng.lib" -I "C:\Documents and Settings\Administrator\My Documents\include"

有人可以关注如何解决这些错误吗？

在使用Microsoft Visual Studio '08编译libpng时，如何避免“错误LNK2005：”（已经定义了stdlib函数）？
