make[1]: *** [GNUmakefile:79：GenFw] 错误 2

根据引用和引用，错误信息"make 错误 2"是由于系统缺少gcc导致的。你可以尝试使用以下命令安装gcc源码包以解决此问题：
yum -y install gcc
这将安装gcc源码包，并解决系统缺少gcc的问题。同时，根据引用，如果你在文件buildroot/output/build/host-ncurses-5.9/include/curses.tail中找到了"/* generated */"这一注释行，请将其去掉。这可能也有助于解决错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
