我意识到使用gcc4编译qemu会带来很多麻烦和痛苦， 所以我在我的linux盒子里安装了gcc-3.2工具链，现在我正在编译qemu， 这些是我遵循的步骤和发出的输出。

但编译因这些错误消息而停止，听起来有点不正确 系统包含路径，所以我用-isystem开关明确地给它。但仍然没有编译 正确。
有关此问题的任何解决方法吗？

答案 0 :(得分：1)
qemu的哪个版本？操作系统？我们需要更多 gold 信息。
例如在我的ubuntu 12.04和git版本的qemu上：
$ git clone git://git.qemu.org/qemu.git > /dev/null
...
$ cd qemu/
$ ./configure --target-list=arm-softmmu --disable-sdl
