我正在尝试运行此处显示的示例代码。我使用 MinGW 从源代码构建 wxWidgets，使用以下命令：mingw32-make -f makefile.gcc SHARED=1 UNICODE=0 BUILD=debug。在我的 Eclipse 设置中，我添加了 -Iwx288/include、-Lwx288/lib、-lwxbase28d_gcc_custom 和 -lwxmsw28d_core_gcc_custom。由于编译方法的数量和链接器的经验不足，我感到非常困惑。我收到这些错误，我做错了什么？我什至没有在我的程序中引用 wxMutex。

我猜你要么在你的包含路径中丢失了一些东西，要么是wxWidgets为了wxWidgets Header-Files正确处理而需要的一些定义

WX 带有一个名为（如果您的构建成功wx-config，应该位于某处）的工具wxWidgets/bin

wx-config是一个shell脚本，你可以使用mingw-msys

wx-config --cxxflags生成编译目标文件所需的所有包含路径和定义。 wx-config --libs负责链接程序所需的一切

我建议wx-config在您的makefile/builder/.... 或检查它产生的输出并将其与您的构建过程进行比较

我当前安装的示例：

$ wx-config --cxxflags --static=no --debug=yes --unicode=no -I/wx/lib/wx/include/msw-ansi-debug-2.8 -I/wx/include/wx-2.8 -D_WXDEBUG_ -DWXUSINGDLL -D_WXMSW_ -mthreads

$ ./wx-config --libs --static=no --debug=yes --unicode=no -L/wx/lib -mthreads -Wl,--subsystem,windows -mwindows -lwx_mswd_richtext-2.8 -lwx_mswd_aui-2.8 -lwx_mswd_xrc-2.8 -lwx_mswd_qa-2.8 -lwx_mswd_html-2.8 -lwx_mswd_adv-2.8 -lwx_mswd_core-2.8 -lwx_based_xml-2.8 -lwx_based_net-2.8 -lwx_based-2.8

你为什么要编译include/wx/thrimpl.cpp？它不是你的文件，它是 wxWidgets 的一部分，它不应该被编译为你的项目的一部分。只需将其从项目文件列表中删除即可。
