linux - Pintos，检查失败。运行未正常启动: no "Pintos booting" message

Question

我发现之前有人问过相关问题PintOS, kernel panic with -v option bochs on ubuntu

但是，我尝试了，但没有成功。 “pintos -- run Alarm-multiple”看起来不错，但是当我执行“make check”时

......

我今天遇到了同样的问题，这是因为我试图将 qemu 设置为默认模拟器，所以我将 utils/pintos 中的第 103 行更改为

$sim = "qemu" if !defined $sim;

但我忘记将threads/Make.vars中的SIMULATOR值更改为

SIMULATOR = --qemu

由于我没有在我的机器上安装 bochs make check 试图在其上运行测试，但无法启动。

请注意，这是测试无法运行的一种情况，也可能是另一个原因，但由于

pintos -- run alarm-multiple

工作正常，我认为这可能与您遇到的问题相同。
