[Insight-users] Compilation issue with simple Hello World (Release vs Debug mode)

[Manuel Grizonnet]

Hi Luis,

thanks for your answer. I am using gold which is a new linker, still in
development, which is faster than the current linker included in binutil.
It replace the ld command on my system.

On my system (Ubuntu 12.04), * ld --version* returns:





*GNU gold (GNU Binutils for Ubuntu 2.22) 1.11Copyright 2011 Free Software
Foundation, Inc.This program is free software; you may redistribute it
under the terms ofthe GNU General Public License version 3 or (at your
option) a later version.This program has absolutely no warranty.*

That's why CMAKE_LINKER is the same as you get when configuring the
standard way.

Note that this linker was installed on my system when I've configured the
CUDA toolkit using .deb provided by NVIDIA following the Ubuntu
documentation:

http://doc.ubuntu-fr.org/cuda

The package is called binutils-gold.

I am not 100% sure that my issue is related with the linker even if gold
already obliged me recently to patch some CMake in OTB project to make it
compile:

http://hg.orfeo-toolbox.org/OTB/rev/6fd5ea11f99b

I will probably try to come back to the standard GNU linker as I've already
had too much trouble with this one but I  am interested for feedback of
other people who try to link there ITK project with it.

Best regards,

Manuel
