wxWidgets项目编译在Windows 10上使用TDM-GCC失败

Question

我试图用TDM-GCC 4.7.1 32位在Windows10上编译wxWidgets 3.0.2项目，我得到以下错误：

编译

mingw32-g++.exe -Wall -pipe -mthreads -D__GNUWIN32__ -D__WXMSW__ -DWXUSINGDLL -DwxUSE_UNICODE -Wall -std=c++11 -g -Wall -std=c++11 -g -Ilibrary\xerces-c-3.1.1\src -Ilibrary\mupdf-1.6\include -Ilibrary\wxWidgets-3.0.2\include -Ilibrary\wxWidgets-3.0.2\lib\wx\include\msw-unicode-3.0\ -Iinclude -IC:\TDM471-32\include -IC:\TDM471-32\include -c F:\Proj\Document.cpp -o obj\Debug\Document.o

我不知道这是否解释了您的问题，但无论如何，在命令行上使用-DwxUSE_UNICODE是错误的，所有wxUSE_XXX符号都应该定义为0或1，而不是空的。但是，即使是-DwxUSE_UNICODE=1也是错误的，因为这可能导致CRT/SDK和wxWidgets头之间的不匹配。相反，您应该预定义_UNICODE和/或UNICODE (前者由CRT使用，后者由SDK使用，但SDK也会选择带有下划线的版本)，wxWidgets也会尊重它。
