If you build and install the binutils and gcc with the same --prefix option, then gcc will use the linker that you built. [Prashant] Now I did, ../binutils-2.21/configure --prefix=/auto/nobackup-bgl-mitg-dev56/prbatra/fresh2/build/ --with-sysroot=/auto/nobackup-bgl-mitg-dev56/prbatra/fresh2/build/sysroo t/ make make install ../gcc-4.1.2/configure --prefix=/auto/nobackup-bgl-mitg-dev56/prbatra/fresh2/build/ --with-sysroot=/auto/nobackup-bgl-mitg-dev56/prbatra/fresh2/build/sysroo t --enable-languages=c,c++,objc make It fails at the same point : /usr/bin/ld: this linker was not configured to use sysroots As, I can see binutls are properly installed at - prbatra@bgl-mitg-dev56:/auto/nobackup-bgl-mitg-dev56/prbatra/fresh2/objd ir$ ls /auto/nobackup-bgl-mitg-dev56/prbatra/fresh2/build/ bin include lib lib64 share sysroot x86_64-unknown-linux-gnu prbatra@bgl-mitg-dev56:/auto/nobackup-bgl-mitg-dev56/prbatra/fresh2/objd ir$ ls /auto/nobackup-bgl-mitg-dev56/prbatra/fresh2/build/bin addr2line ar as c++filt elfedit gprof ld ld.bfd nm objcopy objdump ranlib readelf size strings strip prbatra@bgl-mitg-dev56:/auto/nobackup-bgl-mitg-dev56/prbatra/fresh2/objd ir$ ls /auto/nobackup-bgl-mitg-dev56/prbatra/fresh2/build/x86_64-unknown-linux- gnu bin include lib lib64 libexec Is it that I missed something again?
