           Summary: ld-elf2flt: host/bin/ld.real': execvp: No such file or
                    directory
           Product: buildroot
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: critical

                CC: buildroot at uclibc.org
  Target Milestone: ---

With the rc of 2018.05 preparation, it's not possible to generate uclibc with a
stm32 build. 
During the installation of uclibc, the call to elf2flt crash:

  CC utils/getconf
ld.real (ld-elf2flt): error trying to exec
'/mnt/internal_storage/stm32f7/buildroot_to_test/output/host/bin/ld.real':
execvp: No such file or directory
collect2: error: ld returned 255 exit status

Setup: 
  VERSION of buildroot: 2018.05-rc2
  PC with Ubuntu 16.04

How to reproduce:
  git clone git://git.buildroot.net/buildroot
  cd buildroot
  git checkout -b work 2018.05-rc2
  make stm32f469_disco_defconfig
  make 

Trace of compilation are available on attached file.

Hello Christophe,

Thanks for the report.

I've bisected this issue to the folowing commit:
    f9cffb6af464c5c049daa93d557e485ea61f14a8 binutils: replace hard-links with
soft-links to fix rpath

I've added Thomas in cc of this bug now, as he already investigating the
reason for the offending commit in the first place.

Regards,
Yann E. MORIN.

Hello Chritophe,

I've sent two patches to try and fix this issue:
    https://patchwork.ozlabs.org/patch/920759/
    https://patchwork.ozlabs.org/patch/920760/

I only tried to build stm32f469_disco_defconfig with them, and it
was OK. I can't test-run by lack of hardware, though, so it would
be nice if you could confirm they indeed fix the issue.

Regards,
Yann E. MORIN.

Hi Yann,
  I have made the test with the hardware and your patch.

  compilation with your patch: OK
  Test on board: KO

  I have made several verification:
    runtime execution with stm32f469 configuration:
      version of buildroot     - status

I will create a new bugzilla for the runtime issue.
