[clug] compiling problem

[Duncan Roe]

Hi Adrian,

It seems that on your system, static libc is not installed. If installed, it
would be called libc.a and reside in /usr/lib (or /usr/lib64 on a 64-bit
system). It would be a *big* file:

 21:48:39$ ls -l /usr/lib64/libc.* /usr/lib64/libc_nonshared.a
 -rw-r--r--  1 root root 66473442 2006-05-21 11:31 /usr/lib64/libc.a
 -rw-r--r--  1 root root      210 2006-05-21 11:31 /usr/lib64/libc.so
 -rw-r--r--  1 root root    85288 2006-05-21 11:31 /usr/lib64/libc_nonshared.a

libc_nonshared.a complements /lib/libc.so.n as can be seen from the contents of
/usr/lib64/libc.so:

 21:49:16$ cat /usr/lib64/libc.so
 /* GNU ld script
    Use the shared library, but some functions are only in
    the static library, so try that secondarily.  */
 OUTPUT_FORMAT(elf64-x86-64)
 GROUP ( /lib64/libc.so.6 /usr/lib64/libc_nonshared.a )

It's optional to build static libc when building glibc, looks like the authors
of your distro chose not to do it.

Building glibc from source is possible but not popular with the maintainers. The
config directives have to be just right, or it won't work in my experience.
Post again if you want to try it.

Cheers ... Duncan.
