I am using the learncthehardway.com C tutorial.
I can't see any line numbers in Valgrind when I use it to debug. Valgrind tells me to install glibc.
When I try to configure glibc, it throws this error.
"configure: error: you must configure in a separate build directory"

I have searched, found an answer, didn't understand it. There is a Lot about Linux I still dont't understand. I think it is the way the string is setup. I'm not sure how to format it.

the directory structure is: me@Earth:~/c/glib/glibc-2.15/glibc-build$
glibc-build being the dir i created to configure in.

Thanks in advance.

Ubuntu 12.04., 3.2.0-24-generic-pae,
Valgrind-3.7.0, make 3.81

glibc, in particular, is "very special." But in any case ... if you are using a distro that is based on packages (as I presume that you are), you should make updates by installing or upgrading appropriate packages. You should not be monkeying around with anything that involves "from source," i.e. configure steps.

Why? Because the package system maintains a database of dependencies and co-requisites, and this information must remain authoritative. If you start installing stuff "out of band," it no longer will be.

Figured it out. The problem was that I needed Gawk instead of Mawk. Also, autoconf had to be installed.
Hope this helps someone else.

Now I have a make error.

I tired to make again.

me@Earth:~/c/glib/glibc-2.15$ make

here is my glibc error log: http://pastebin.com/4etjYYGG

(G)libc is your OS ( together with the kernel )
... and is always installed. May be 'libc6-dev' is missing.

Ubuntu 12.04, package name = libc6
http://packages.ubuntu.com/precise/libc6

If you change anything : Do not expect your OS to work. Ever.

Building glibc 2.15
http://www.linuxfromscratch.org/lfs/...r06/glibc.html
Be aware that glibc requires a build directory outside glibc-2.15/ source.

I am following learncthehardway.com's C tutorial. The problem started with me not having line numbers. valgrind asked for glibc version 2.1, I think. I'm not seeing that error now, its been two days chasing whatever the compiler is telling me is missing.

I still cant get line numbers for errors. I probably just don't know what to expect from valgrind.

Hhere is what i get when there is an error. Again, no line numbers.
