crosstool-ng详解

3.1. 关于crosstool-ng本身的一些背景知识和逻辑

如上所述，用list-steps，可以查看到，当前，用crosstool-ng去build，去制作交叉编译器，具体分成哪些步骤：

CLi@PC-CLI-1 ~/develop/crosstool-ng/crosstool-ng-1.18.0_build
$ ct-ng list-steps
Available build steps, in order:
  - libc_check_config
  - companion_libs_for_build
  - binutils_for_build
  - companion_libs_for_host
  - binutils_for_host
  - cc_core_pass_1
  - kernel_headers
  - libc_start_files
  - cc_core_pass_2
  - libc
  - cc_for_build
  - cc_for_host
  - libelf_for_target
  - binutils_for_target
  - debug
  - test_suite
  - finish
Use "<step>" as action to execute only that step.
Use "+<step>" as action to execute up to that step.
Use "<step>+" as action to execute from that step onward.

        

知道了，此处分了多少步骤，具体有哪些步骤之后

后面才有可能去实现，从之前出错的哪一步，恢复，继续编译。
