Bug 8256

Thanks for your bug report. Can you first make sure that you can reproduce the issue after doing a full rebuild, i.e after doing "make clean all" ?

Once you have verified this, could you please give us:

 
 - The Buildroot version you're using
 - The exact steps to reproduce the issue

 - What you mean exactly by "gmake process points to the host /usr/bin/objcopy". make doesn't "point" to anything, so this sentence doesn't make a lot of sense.

Also, please attach the last 100 lines of the build output, which contain the build failure you're seeing. Thanks!

Further investigation results:

Before launcing gmake, I have  now executed the following command

setenv PATH "/home/elinux/localinstall/buildroot-2015.05/install/buildroot-2015.05/output/host/usr/x86_64-buildroot-linux-uclibc/bin:/home/elinu
x/localinstall/buildroot-2015.05/install/buildroot-2015.05/output/host/usr/bin:${PATH}"
set PATH = "/home/elinux/localinstall/buildroot-2015.05/install/buildroot-2015.05/output/host/usr/x86_64-buildroot-linux-uclibc/bin:/home/elinux

I am available for futher concerns
Thanks a lot.

Why are you using 'gmake' instead of 'make' ? Are you perhaps building on a non-Linux system? If so, which one?

The OS is  RedHat 5 running on a X86 machine (32bits)

I am using "gmake" to build "buildroot 2005.05" but I could use "make". The result should be the same.

For information, I have already build successfully "buildroot" using the same procedure "gmake" and
I sucessfully generated toolchain, Uimage, uboot.bin for others targets like "freescale sabre board" and others.

So, this issue "could be" linked to Minnow Max Target or X86_64 toolchain running on a x86(32bits) host.   

Thanks again.

As you suggested, I executed the MakeFile using "make" instead of "gmake" command.
The result is exactly the same (same reports, same errors).

Do you have an idea for the next steps or experiments I need to do.

Thanks in advance for your support.

configuration execution issue within grub2-2.00 directory

Updating PATH variable before running 'make'.
The compilation go further but an error is still occuring.

I don't know why you think it's a good idea to add the target binaries to your PATH. Don't do that.

The config.log of attachment 6136 [details] is useless. Could you re-run a clean build without hacking PATH, and then attach the full output/build/grub2-2.00/config.log please?

My conjecture is that grub2 is using the wrong objcopy somewhere in configure.
Oh, indeed, now I see: we use HOST_CONFIGURE_OPTS, so it will have OBJCOPY=/usr/bin/objcopy explicitly. I guess we should override that with OBJCOPY=$(TARGET_OBJCOPY), but I'm not sure how that will affect other host,target combinations...

Thanks for your feedback.

I will execute the buildroot as requested and provide you with the config log.

In parallel, I launched buildroot using Virtual Box and CENTOS 7.
Buildroot is correcty working as the host 'objcopy' utility is using 
a compatible version allowing x86_64 binary.
It seem confirm your guess concerning 'objcopy' version differs between Host and Target. This is my case under RedHat Linux 5 (eq Centos 5). This issue doesn't exist under Centos 7. 


Thanks again.

Fixed by http://git.buildroot.net/buildroot/commit/?id=890c9e761b70f28c2f2d6c4cf389e418c6d2b32c. Thanks Arnout for the investigation and fix!
