解压后gcc-10-source_10.2.0-8ubuntu1_all.deb，我进入目录usr/src/gcc-10，然后发出命令：
$ debian/rules control
我下载了文件夹中的先决条件，src/
然后创建build/目录并chdir进入其中
我发出了配置命令：
$ ../src/configure -v --with-pkgversion='Ubuntu 10.2.0-8ubuntu1' --enable-languages=c,c++ --prefix=/usr/local/gcc-10/ --with-gcc-major-version-only --program-suffix=-10 --enable-shared --enable-linker-build-id --without-included-gettext --enable-threads=posix --enable-nls --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --with-default-libstdcxx-abi=new --enable-gnu-unique-object --disable-vtable-verify --enable-plugin --enable-default-pie --enable-multiarch --disable-werror --with-arch-32=i686 --with-abi=m64 --with-multilib-list=m32,m64 --enable-multilib --with-tune=generic --enable-offload-targets=nvptx-none,hsa --enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu
然后我开始编译源包
$ LIBRARY_PATH=/usr/lib32 time make -j 8 | tee ../build-gcc-10.2.lo
但过了一会儿我收到了错误信息：

checking whether the C compiler works... no

供您参考，如果我提取没有 Debian 补丁的软件包gcc-10.2.0.tar.xz并放弃相同的过程，则软件包可以顺利编译而不会出现错误！
