安装lat mingw-w64版本8.1.0后，我认为并设置env和Makefile来构建win32 dll（\ i686-8.1.0-win32-dwarf-rt_v6-rev0 \ mingw32 \ bin），我在遇到这些错误无法识别文件格式：
C：/Mingw-w64/i686-8.1.0-win32-dwarf-rt_v6-rev0/mingw32/ i686-w64-mingw32 / lib / libws2_32.a：无法识别文件格式;视为链接脚本
令我惊讶的是，即使以minw-w64格式提供的自己的库也无法识别。
这是makefile：
# MinGW 32 makefile
#
# Change vars MINGW and MINREL in accord to your compiler path/release
#
MINGW =C:/Mingw-w64
MINREL =8.1.0
