Yeah, it's pretty hairy. Or, at least it has more knowledge about ld.so than I could claim to have. There is a target in the Makefile that seems like it tries to rewrite the script if configure didn't detect that you have bash-2+. You can look at the Makefile in elf/ and look for something like sh-ldd-rewrite. But we have bash, so I see no reason not to use it if that's what they had in mind. > > So, I'm proposing that we force > > /bin/bash as the shebang for ldd. Two possible ways are: > > > > 1.

I'll wait a bit longer to see if anyone else wants to chime in. -- Dan -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
