Problems linking with libc6

[Vincent Stemen <vstemen at crel dot com>]

Please help.  When trying to compile gcc with libc6.  I get

undefined reference to `fstat'
and
undefined reference to `stat'

I get similar errors when attempting to compile gcc-2.95.2 and egcs-1.1.1.

I have tried with glibc-2.1.1 and glibc-2.1.2 and I have tried
compiling with gcc-2.95 and gcc-2.7.2.3.

The only combination that I have successfully compiled gcc-2.95.2 with
is egcs-1.1.1 with native libc-5.4.23.

Here are the errors I get compiling gcc-2.95.2 with gcc-2.95 and native
glibc-2.1.2

I used the basic configure options,
configure --enable-shared --prefix=/usr

I am running Linux on an ix86 and compiling with kernel source headers
from linux-2.2.12.


I finally found the following in the glibc FAQ:

==============
{RM} Believe it or not, stat and lstat (and fstat, and mknod) are supposed
to be undefined references in libc.so.6!  Your problem is probably a missing
or incorrect /usr/lib/libc.so file; note that this is a small text file now,
not a symlink to libc.so.6.  It should look something like this:

GROUP ( libc.so.6 libc_nonshared.a )
==============

but my /usr/lib/libc.so is a text file.  It contains the following
(exactly the way "make install" for glibc installed it.

/* GNU ld script
   Use the shared library, but some functions are only in
   the static library, so try that secondarily.  */
GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a )


Does anybody know what else could be causing this problem?  I was able
to compile and run major packages such as emacs and Xfree86 with glibc
but I cannot get the development packages to compile.  I get various
other failures compiling such packages as binutils, and libg++ in
addition to the errors above with gcc.

I have posted about this problem to gnu.glibc.bug but have gotten no
response so far.


Thanks in advance.
