linux - 如何让busybox1.23.2编译成功？

Question

包:busybox 版本:1.23.2 当我制作 busybox 时，它会产生意想不到的结果。 我用的crosschaintool是ARM/uClinux Toolchain arm-2010q1-189-arm-uclinuxeabi-i686-pc-linux-gnu，但是我做不了busybox，像这样:

root@ubuntu:/busybox/busybox-1.23.2# make
  SPLIT   include/autoconf.h -> include/config/*
  GEN     include/bbconfigopts.h
  HOSTCC  applets/usage
applets/usage.c: In function ‘main’:
applets/usage.c:52:3: warning: ignoring return value of ‘write’, declared with attribute warn_unused_result [-Wunused-result]
   write(STDOUT_FILENO, usage_array[i].usage, strlen(usage_array[i].usage) + 1);
   ^

我该怎么办？ busybox 不能使用 ARM/uClinux 工具链吗？我该怎么办？如果您能给我们一些建议和指导，我们将不胜感激，谢谢!

LINK busybox_unstripped Trying libraries: crypt m Library crypt is not needed, excluding it Library m is not needed, excluding it Final link with: arm-uclinuxeabi-strip:busybox_unstripped: File format not recognized Makefile:723: recipe for target 'busybox' failed make: *** [busybox] Error 1

由于整个编译日志只有一段，建议如下:

1) 请从头检查编译日志是否有其他重要的警告或错误。

2) busybox_unstripped 文件是否生成？查看makefile dependencies，查看是否所有的依赖文件都生成成功。从日志中，一些库被排除在外，因此您可能需要检查 busybox 配置文件。

3) 如果生成了busybox_unstripped文件，检查makefile中“Final link with:”的链接语法。为使跨工具链链接成功，请确保链接命令正确。

祝你好运!
