android - mipsel-linux-gcc : Command not found

Question

我正在尝试使用 mipsel-linux-gcc 编译器交叉编译内核和 rootfs。主机是64位的，而要构建的rootfs是32位的。我尝试安装ia32-libs和ia32-libs-multiarch。但失败了。我已经使用 apt-get 安装了 gcc-multilib。但是，我无法构建。我已将 PATH 变量更新为所使用的工具链。

echo $PATH

usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/toolchains/stbgcc-4.5.3-1.1/bin

我得到的错误:

但是我得到的 mipsel-linux-gcc 给出了正确的答案

which mipsel-linux-uclibc-gcc
/opt/toolchains/stbgcc-4.5.3-1.1/bin/mipsel-linux-uclibc-gcc

我需要导出的变量可能是什么？

Answer 1

我遇到了“找不到命令”的问题。尝试安装 ia32-libs，或者如果未找到，请尝试建议的 lib32z1 lib32ncurses5 lib32bz2-1.0 软件包。这解决了我的问题。
