我在 riscv-rootfs 目录的时候遇到这个问题运行 make rootfsimg
问题如下

compilation terminated.
make[3]: [scripts/Makefile.build:198: applets/applets.o] Error 1
make[2]: [Makefile:372: applets_dir] Error 2
解决方法如下，在另一位同学的协同下，发现riscv-rootfs/apps/busybox/config文件有个环境变量-“RISCV"没有被提及导致这个问题出现
部分原文如下# Build Options
#
解决方法把RISCV设置为自己编译的工具链的目录。
我的为~/riscv64-linux .(加上sysroot之后是 ~/riscv64-linux/sysroot）
到此问题解决。
下一个问题如下，好像是工具链的版本不兼容，不知道能否提供以下可用的版本号呢？

Note: if build needs additional libraries, put them in CONFIG_EXTRA_LDLIBS.
Example: CONFIG_EXTRA_LDLIBS="pthread dl tirpc audit pam"
