我尝试在win10中安装gcc（64位，并行） 它适用于64但不适用于32 - 就像这样工作
C:\Users\me\Desktop>gcc -m64 -o test64 testt.c
- 但它不是......
C:\Users\me\Desktop>gcc -m32 -o test32 testt.c

我该如何解决？
答案 0 :(得分：0)
cygwin x86_64的gcc编译器仅适用于x86_64 64位。
如果你想编译cygwin x86，32位，你需要安装32位的cygwin及其编译器。
如果您想要编译32位的Windows，则需要安装交叉编译器
mingw64-i686-gcc-core GCC for Win32 (i686-w64-mingw32) toolchain (C, OpenMP)
对于Windows 64位，交叉编译器
mingw64-x86_64-gcc-core GCC for Win64 toolchain (C, OpenMP)
您还需要安装相关库。 完整的包装清单可在 https://cygwin.com/packages/package_list.html
