While trying to compile gcc (HEAD of 2007-08-27) for a sysrooted environment in
/tmp/gc where glibc 2.6.1 is already installed there, ld complains:
/usr/i686-pc-linux-gnulibc2/lib/gcc-lib/i686-pc-linux-gnulibc2/3.3.3/../../../../i686-pc-linux-gnulibc2/bin/ld:
cannot find /tmp/gc/lib/libc.so.6 inside /tmp/gc.
The file /tmp/gc/lib/libc.so.6 is perfectly there.
This is what I did exactly:
- use linux kernel source 2.6.22.5, configure and
make INSTALL_HDR_PATH=/tmp/gc headers_install
- configure glibc-2.6.1 with
CFLAGS=-march=i486 ../configure --prefix=/tmp/gc \
--disable-nls --enable-add-ons
and install
- configure gcc (from svn 2007-08-27) with
configure --prefix=/tmp/gc --disable-nls --enable-shared \
--with-sysroot=/tmp/gc --enable-languages=c i686-pc-linux-gnulibc2
The version of ld used was 2.17.50.0.18.20070731 from kernel.org. However,
in all versions of ld between 2.17 and 2.18.50.20070828 that I looked at, the
code mentioned below is the same.
The following patch fixes the problem for us:
