I forgot to set a make --prefix and I think it wrote to /usr/local/ by default and now I'm having all kinds of errors. I'm on ubuntu natty, what's the easiest way to resurrect glibc. I've tried to uninstall/reinstall using apt-get, and dkpg-reconfigure on libglibc2.0-dev but didn't work. I tried to download glibc from source and it gave error "sorry, unimplemented: inlining failed in call to ‘syslog’: function body not available". Apparently I have to rebuild gcc pass it kernel headers and do all sorts of devilry the least of which I understand.

I don't really want to have to reinstall everything if possible any help would be appreciated.

edit: Looks like it overwrote during install /usr/local//lib/libm.a /usr/local//lib/libc.a

$ ldd /bin/ls =>  (0x00007fff453ff000) => /lib/x86_64-linux-gnu/ (0x00007fdcd202f000) => /lib/x86_64-linux-gnu/ (0x00007fdcd1e27000) => /lib/x86_64-linux-gnu/ (0x00007fdcd1c1e000) => /lib/x86_64-linux-gnu/ (0x00007fdcd188a000) => /lib/x86_64-linux-gnu/ (0x00007fdcd1686000)
/lib64/ (0x00007fdcd2271000) => /lib/x86_64-linux-gnu/ (0x00007fdcd1467000) => /lib/x86_64-linux-gnu/ (0x00007fdcd1262000)

According to this site for it to work I have to make some modifications for things not to break when I am compiling, but it would be nice if I could somehow undo the mess I made. I lack a fundamental understanding of how a lot of this works.

This question came from our site for professional and enthusiast programmers.

Try ldd /bin/ls first to see if that program uses the right libc. – Fred Foo Jun 25 '11 at 18:26
You could try booting with the install cd in recovery mode, but I've only ever done that on RHEL. – Corey Henderson Jun 25 '11 at 18:28
ls seems to be using the libraries from the right places, i.e. not from /usr/local/lib, where these libraries shouldn't be doing any harm anyway. – Fred Foo Jun 25 '11 at 18:38
I've tried several different sources I had already compiled before that worked fine, they give errors like "undefined reference to X" and "Y.h: present but cannot be compiled check for missing prerequisite headers?" I'll try dpkg-reconfigure -all and if that fails I'll try recovery mode. Thanks guys – ForeverConfused Jun 25 '11 at 18:46
