Question

我正在尝试编译使用wxWidgets库创建的现有项目。我成功编译了wxWidgets 2.8.12库。现在，我正在尝试编译我的项目。但我得到错误：

fatal error LNK1104: cannot open file 'wxbase28d.lib'

之后我在以下设置中添加了一些变量：

C / C ++ - ＆gt;预处理器定义：

WIN32;__WXMSW__;_WINDOWS;_DEBUG;__WXDEBUG__;_CRT_SECURE_NO_WARNINGS;WIN32;_DEBUG;_WINDOWS;%(PreprocessorDefinitions)

VC ++目录 - ＆gt;包含目录：

D:\instantclient_12_1\sdk\include;$(WXWIN)\lib\vc_lib\mswd;$(WXWIN)\include;$(VCInstallDir)include;$(VCInstallDir)atlmfc\include;$(WindowsSdkDir)include;$(FrameworkSDKDir)\include;

链接器 - ＆gt;常规 - ＆gt;其他图书馆目录：

$(WXWIN)\lib\vc_lib;E:\app\vasyl\product\11.1.0\db_1\OCI\lib\MSVC\vc71;$(WXDIR284)\lib\vc_lib;%(AdditionalLibraryDirectories)

资源 - ＆gt;常规 - ＆gt;其他包含目录：

$(WXWIN)\include;c:\wxMSW284\include;$(WXDIR284)\include;%(AdditionalIncludeDirectories)

现在，情况是这样的：

1>MSVCRTD.lib(MSVCR100D.dll) : error LNK2005: _free already defined in LIBCMTD.lib(dbgfree.obj)
1>MSVCRTD.lib(MSVCR100D.dll) : error LNK2005: _malloc already defined in LIBCMTD.lib(dbgmalloc.obj)

1>MSVCRTD.lib(MSVCR100D.dll) : error LNK2005: __vsprintf_p already defined in LIBCMTD.lib(vsnprnc.obj)
...
...
etc.

有人能帮助我发现我做错了吗？

Answer 1

您正在为项目和库使用不同的CRT设置（静态与DLL）。确保使用/MD[d]或/MT[d]相同的选项（重新）构建它们。

此链接器错误可能有多种原因。要检查的第一个地址是MSDN：https://msdn.microsoft.com/en-us/library/ts7eyw4s.aspx

什么是$(WXWIN)，它与$(WXDIR284)的区别如何？看来，你包括两次wxWidgets路径......
