Description Feng Haibo 2011-06-04 05:14:26 UTC

Enviornment: Fedora 15 
I downloaded buildroot-20110603.tar.bz2, unzipped it, only saved directly to use the default values in menuconfig. Then do a simple "make". I got a compile error when compiling binutils-2.21, the error is:

# gcc >= 4.3.0 have to also build all-target-libgcc
/usr/bin/make -j2 -C /home/haibo/learn/buildroot/output/toolchain/gcc-4.3.5-intermediate all-gcc all-target-libgcc

I could work around this problem by doing the following:
$cd /usr/lib
$rm libc.so
$ln -s /lib/libc.so.6 libc.so

But this is not the best way, because ASCII file /usr/lib/libc.so's missing incurs other problems, fox example "make menuconfig" fails to launch

Huh, is your system libc corrupt? Are you building as root?

I notice this workaround , is wrong , no,  /usr/lib/libc.so is not missing  ,
/usr/lib/libc.so, is in glibc-devel package.
Sometimes, also, some people do this wrong workaround when need the static libraries which normally are in a package glibc-static

Many people routinely build toolchains with Buildroot without seeing this problem, and we haven't had further details from the initial bug reporter since several months. I'm therefore closing this bug. Anyone seeing the issue is invited to reopen the bug with more details.
