 Please provide at least your .config.
Also i think that this is a duplicate of a nofpu eabi report, so please check.

 I have the same problem with gcc-3.4.6 and arm eabi : see bug 1114

 I looked at bug 1114 and it seems to be the opposite. I make all of stephaneC's fixes, and the problem is the same. The make continues to show "armelf_linux_eabi" as the unregnized emulation, with "armelf_linux" and "armelf" as the accepted ones.

 Did any of you read the fine helptext of BR2_GNU_TARGET_SUFFIX ?
 
(0002072)
stephaneC
01-30-07 06:41

 pferrell :
BR2_GNU_TARGET_SUFFIX="linux-uclibc"
[snip]/arm-linux-uclibcgnueabi-ld: unrecognised emulation mode: armelf_linux_eabi
Supported emulations: armelf_linux armelf

me :
BR2_GNU_TARGET_SUFFIX="linux-uclibcgnueabi"
[snip]/arm-linux-uclibcgnueabi/bin/ld: unrecognised emulation mode: armelf_linux
Supported emulations: armelf_linux_eabi armelfb_linux_eabi

I'm a little bit confuse about that !

If I understand the solution is :
for pferrell :
add "gnueabi" or "eabi" to BR2_GNU_TARGET_SUFFIX
=> BR2_GNU_TARGET_SUFFIX="linux-uclibcgnueabi"

for me :
remove "gnueabi" from BR2_GNU_TARGET_SUFFIX
=> BR2_GNU_TARGET_SUFFIX="linux-uclibc"

correct ?

(now I work with latest gcc 4.2 and it's ok)

 bernhardf,
I read the fine help text, changed my BR2_GNU_TARGET_SUFFIX, and re-ran with the same error. I then deleted my entire buildroot directory, re-did it from stratch and still get the same result. Nothing I change seems to have any effect on the "Supported Emulations". The only other notes I can raise are that I am using a VMWare emulator, and have tried fedora core 5 and 6.

 During the last week, i changed quite a bit in that area. arm for an integrator with EABI now builds for me flawlessly.
An XScale EABI with a default for big-endian builds too, fwiw.

Please svn up and rebuild and let me know if that's better now.

 I have now gone through every combination of gcc and binutils (big and little endian) and none of them successfully complete buildroot. The unknown emulation error is limited to the combination of gcc 4.1.1 and binutils 2.16.1. There was no change after the latest updates, it spits out the same error. I'm starting to wonder if this is purely an error with the VMware emulation, so I'm trying to get a friend running a full Linux box to try it. With any other combination of gcc and binutils the only errors listed before it stops running are "makeinfo is missing on your system" and "nothing to be done"

 Just trying the config pasted above..
I'm using binutils-2_17_50_0_10 since the 2.16.1 is not even the current stable one, fwiw.

Of course i'm using linuxthreads since there simply is no NPTL support for arm yet, just linuxthreads or linuxthreads.old

 if you want to use EABI, then use linux-2.6 headers
