[SOLVED] building coreutils... functions already defined

frozenQueue · 09-13-2010, 05:15 PM

I'm building the GNU Coreutils with gcc. However, each attempt to build fails with gcc complaining that the code redefines a function that has already been defined.

Code:

tee.c:35: error: conflicting types for ‘tee’
/usr/include/bits/fcntl.h:254: note: previous declaration of ‘tee’ was here

I "fixed" that by changing the name of "tee" in the Coreutils source code. But then another error came up for another function:

Code:

test.c:142: error: static declaration of ‘eaccess’ follows non-static declaration
/usr/include/unistd.h:297: note: previous declaration of ‘eaccess’ was here

Why is the Coreutils code including these headers if it wants to redefine the functions? Should I be passing in some compiler switch that allows the latest definition to be used?

Might help if you told us which version of coreutils and what steps you have followed up until the errors you have received?

version 5.0

1. Downloaded coreutils from gnu.org.
2. "./configure --prefix=/vm/drv85M-0000-p1 --datadir=/vm/drv85M-0000-p1/usr/include --infodir=/vm/drv85M-0000-p1/usr/share/info --mandir=/vm/drv85M-0000-p1/usr/share/man"
3. "make"

I'm trying to see if I can assemble a tiny Linux system in a very small vm image by building the components externally.

Well my initial thoughts when seeing such an old version (ie latest is 8.5) that maybe the changes since that version to the location
of headers and information stored in them may have changed quite a bit (i could of course be way off)

Have you perhaps tried the same but with a newer version?
I personally have only compiled this using the instructions from LFS so maybe they can help you.

You'll need to match your coreutils version with your glibc/libc version. If you are using glibc>=2.4 you'll need to use a much more modern coreutils. If glibc>=2.9 use the *latest* coreutils.

The old version was definitely the problem. I grabbed 5.0 thinking it was the latest version, but when I looked again, I saw it wasn't. Version 8.5 builds without issues.
