compilation - 使用自动工具编译：追溯更改配置标志

Question

假设我用自动工具编译了一个项目（不是我自己的）并传递了一些标志来配置。现在我想再次编译同一个项目，但配置标志略有不同。有没有办法告诉配置脚本使用旧标志，但用一些额外的标志更新它们？

I would love to see an easier approach, but to simply add flags you can do:

sed -i '/^ac_configure_extra_args=/s/$/--new-flag --other-flag/' config.status
./config.status --recheck

Normally, I manually edit config.status to do this, and not all sed support -i, but you get the idea. Change the original flags as they are defined in config.status to be the flags you want.

Another option is to cut-n-paste the original configure invocation out of the top of config.log and edit it.
