C++ 尽管在zlib.lib中链接，但未解析外部

我一直在尝试编译一个应用程序，它在VC++2010中利用zlib压缩

我明白了

error LNK2019: unresolved external symbol _inflateInit2_ referenced in function ...

错误消息，如果我没有链接lib，这是正常的。我链接了静态版本zlib库

我已经设法使libs和header的这种完全相同的配置在不同的解决方案中完美地工作，因此这种行为非常出乎意料

如有任何意见，将不胜感激

您是否验证了zlib函数原型是否位于

extern“C”

块中？如果未验证，则链接器将查找具有C++损坏名称的函数，而zlib.lib将包含未混合的C名称。

您使用VC++2010以外的其他工具编译了zlib静态库

这是VS2008/05的最新升级吗

---

您是否尝试过使用2010工具集重新编译静态库？

一些暗中操作的建议：

尝试运行

dumpbin/symbols zlib.lib

，查看该lib中的符号是否如您所期望的那样（即，

inflateInit2

）

如果生成当前依赖库路径搜索来定位

zlib.lib

，请尝试指定库的完整绝对路径，以排除链接器在系统上的其他位置查找过时的zlib库

另外，发布用于链接器的命令行（来自构建日志文件）

更新：

如果您意外地混合了32位和64位组件（即，

zlib.lib

文件是为x86构建的，而应用程序是为x64构建的），则可以看到类似的行为。链接器不会抱怨找不到lib文件，也不会抱怨lib文件中的对象用于不同的平台。鉴于您的错误消息中提到了一个没有任何修饰的符号，我打赌链接器正在构建x64应用程序，但zlib.lib可能有x86对象（因此，其中有一个名为

\u inflateInit2

的符号，用下划线或其他符号装饰）

---

（顺便说一句，我想知道是否可以在同一个lib文件中混合x86和x64对象，只要它们有不同的名称。但我并不想实际这样做）

---

这可能是问题的根源吗？

如果您使用的是contrib/中提供的VS2010解决方案，请注意它有错误。zlibstat项目定义了ZLIB_WINAPI，它根据用于打开STDCALL约定。只需将其从项目设置中删除并重新编译库。

在我的情况下，我修改了它

• 配置->链接器->输入->其他依赖项

读取

ucrt.lib；vcruntime.lib；msvcrt.lib；kernel32.lib

这使libz能够使用VS2015在Windows 10下构建

确保生成类型为/MD

---

如果为libpng构建（需要zlib），同样的修改可以成功构建旧的包含默认“项目”文件。

我自己在使用Visual Studio 2017时也遇到了同样的问题。我收到了如下错误消息：

error LNK2019: unresolved external symbol __imp__deflate referenced in function 
error LNK2019: unresolved external symbol __imp__deflateEnd referenced in function 
error LNK2019: unresolved external symbol __imp__inflate referenced in function 
error LNK2019: unresolved external symbol __imp__inflateEnd referenced in function 
error LNK2019: unresolved external symbol __imp__deflateInit2_ referenced in function
error LNK2019: unresolved external symbol __imp__inflateInit2_ referenced in function

我遵循Michael Burr的提示，检查zlib文件中是否包含以下方法：

dumpbin /symbols zlib.lib

输出显示方法存在，但VisualStudio仍在抱怨。最终，我从他们的github存储库下载了zlib的最新稳定版本，然后（使用VisualStudio开发人员控制台）对其进行编译。他们的说明没有直接帮助，但最终我找到了他们的MS Makefile，其中包含我需要运行的命令

nmake -f win32/Makefile.msc

查看他们的win32/Makefile.msc文件，了解有关构建过程的更多信息

构建过程生成了两个.lib文件。我在项目中真正需要的是一个名为“zdell.lib”的文件（有关详细信息，请参阅他们的文档文件DLL_FAQ.txt）。回到Visual Studio，我必须手动将该文件添加到我的项目中（不使用

链接器-->常规-->附加库目录

方法，因为这会引发其他问题。）您可以通过右键单击解决方案对象来添加它们（不是列表中最上面的项，而是第二项。在下图中，我的项目名为Lasso，因此您希望单击项目中的等效项。）

转到：添加-->现有项

然后选择生成的zdll.lib文件

---

在我的情况下，在vs2017内安装

zlib-vc140-static-64

（v1.2.11）或

zlib_native

（v1.2.11）。

所有功能原型都在外部“C”中“根据标准zlib.h头进行块。此库与编译项目时使用的VC++2010完全相同。它还成功地用于使用相同的zlib处理代码编译其他项目。所有必需的符号似乎都以dumpbin的形式出现。”
