我的平台是Ubuntu 18.04和Bochs 2.6.9。
编译错误信息如下所示：

make[1]: Entering directory '/home/shore/MineOS/Source/bochs-2.6.9/bx_debug'

我的配置也如下所示

./configure --enable-plugins --enable-debugger --enable-disasm --enable-readline --enable-cpu-level=6 --enable-smp --enable-x86-64 --enable-avx --enable-a20-pin --enable-fast-function-calls --enable-all-optimizations --enable-x86-debugger --enable-alignment-check

我实际上需要调试，所以最好是从源代码编译。
谢谢。
