           Summary: Allow use of older external toolchains without sysroot
                    support
           Product: buildroot
           Version: 2010.02
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: cls at seawood.org
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


I'm using buildroot to create packages that are binary compatible with the
default rootfs provides in my Patriot Corza NAS.  As such, I'm unable to
upgrade to a newer toolchain that supports --sysroot.

The attached patch updates package/Makefile.in, ext-tool.mk and various package
.mks to allow buildroot to be built with an external toolchain that does not
use --sysroot (gcc-3.4.6, in my case).  The use of --sysroot is now controlled
by the BR2_TOOLCHAIN_EXTERNAL_SYSROOT option.  

Most of the other changes just involve passing TARGET_CONFIGURE_ENV to the
configure or make calls for each package.

There's also a change to override the broken getline detection in sed when
using an external glibc toolchain.

Thanks for this patch.

In the past, we tried to handle toolchains not supporting --sysroot, but that
proved to be very difficult with packages such as the Gtk stack or Qt. See for
example the thread at
http://lists.busybox.net/pipermail/buildroot/2008-November/023870.html or
http://lists.busybox.net/pipermail/buildroot/2008-December/024147.html.

Does your patch works when compiling Qt, for example ?

I have not systematically tested every package in the tree.  I only tested the
ones needed for the Corza packages.  However, I just tried Qt and it built
fine.

This is more an enhancement request than a real bug.

Two years later, sysroot capable toolchains are much more common, and we
definitely don't want to add the complexity to add non-sysrooted toolchains
into Buildroot.
