Hi,

I am trying to compile a mips64 cross toolchain. the attached file
ctng.1.6.0.mips64.patch contains some patches I made to crosstool-ng
1.6.0. the build process finished successfully with this patch, but
while compiling some source codes, mips64-octeon-linux-gnu-ld failed
with the following message:

as you can see, the 'emulation specific options' is elf32btsmipn32 but
i think it should be elf64btsmip.

the ctng config file for mips64-octeon-linux-gnu is also attached to this mail.

my host:

my question is:
1) mips64 is not supported by crosstool-ng 1.6.0, why?
2) how can i change the emulation specific options of
mips64-octeon-linux-gnu-ld to elf64btsmip?

sorry for bad english, any help will be appreciated.

Thanks very much.

Cool! It will be nice to have mips64 in crosstool-NG once this issue is
solved! :-)

I built the same toolchian using your patch and your .config.

This path looks like an /old/ installation of a toolchain built with the
original crosstool. Could you check that you do not have an old toolchain
in your PATH ?

Anyway, I can reproduce the issue here as well. But as I'm no MIPS64 expert,
I do not have a clue on how to solve it.

It looks to me that binutils *might* be the culprit here.

Because you are the first one to need it! :-)

> 2) how can i change the emulation specific options of

Look at the binutils configury stuff, maybe there is an issue in there.
buildroot seems to have MIPS64 support. Maybe you could look at how they
build their toolchain? Also, try to google for the issue.

I am a bit short on time to investigate myself, sorry I can't help too
much... :-/

> sorry for bad english,

Well, I have read english far worse than yours! :-) And I'm not a native
english spaeker either!

[-- Attachment #1: Type: text/plain, Size: 1406 bytes --]

check the patch attached to this mail.

put this patch into
/usr/local/lib/ct-ng-1.6.0/patches/binutils/2.19.1, recompile the
toolchain, the ld will work just as i wished.
the patch also works for binutils-2.20.

for those who do not want to apply this patch, take a look at
http://ftp.gnu.org/old-gnu/Manuals/binutils-2.12/html_node/binutils_20.html,
the emulation can be selected at runtime.

I've used this toolchain to compile more than 130 different programs,
including linux kernel 2.6.31, it works just fine for me. i will be

it is ok.
