glibc based toolchain for mips

glibc based toolchain for mips

[Prashant Viswanathan]

[-- Attachment #1: Type: text/plain, Size: 329 bytes --]

Hi,
 
Is it possible to get a free/open glibc based toolchain for MIPS? Buildroot
and ucLibc based toolchain seems to work well, but I really need a glibc
based toolchain. Though I can use the SDE from MIPS technologies to build
the kernel, I can't seem to use it as a toolchain to compile my own
applications.
 
Thanks
Prashant

Debian provides a complete native toolchain with glibc, which I've used
with great success.  (You will need to do a nfsroot or nbd-root if you
don't have local storage.)

That one Debian provides is for big endian. Is there one tool chain
for mips little endian and also gcc 3.*.* ?

Debian has a BE "mips" port and a LE "mipsel" port.  They should both
work (though I've only used the BE version myself) and are routinely
tested...  in fact AFAIK the package build machines are self-hosting.

Could you give me a link to the mipsle cross tool chain? I can only
find the BE cross tool chain.

I'm sorry, I was referring to the *native* mipsel port, not a
crosscompiler.  I didn't even know that Debian was providing a BE cross
toolchain.  (What's that link, btw?  It could be useful to me.)

The mips_4KCle packages in the ELDK are for mips little endian; we
use 3.3.3; see http://www.denx.de/ELDK.html

Hi, Wolfgang,

I download the package. after installation,  the 4KCle is still
linking to the mips-linux-, which is big-endian.
thanks

Please explain exactly what you did.

We have kernel, all libraries and apps running in  this  environment,
and if I check it looks very much like little endinan, for example:

$ file /opt/eldk/mips_4KCle/bin/bash
/opt/eldk/3.1.1/mips_4KCle/bin/bash: ELF 32-bit LSB executable, MIPS, version 1 (SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), stripped

versus

$ file /opt/eldk/mips_4KC/bin/bash
 /opt/eldk/3.1.1/mips_4KC/bin/bash: ELF 32-bit MSB executable, MIPS, version 1 (SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), stripped

Re: glibc based toolchain for mips

[rolf liu]

Sorry I didn't say it clearly.

The files in /opt/eldk/mips_4KCle are in little endian mips, for sure. 
What I want is a cross-development tools for i386-to-mipsel, including
the corss gcc, binutils, other libs. I couldn't find such tools :(

thanks

Please read the documentation. You  will  find  these  tools  in  the
/opt/eldk/bin resp. /opt/eldk/usr/bin directories.

The README.html (or the DULG at http://www.denx.de/twiki/bin/view/DULG/Manual)
documents in detail what needs to be done to install and use the tools.

Thanks. But what I am really looking for is to cross-compile on a Linux i386
host. I think the SDE from MIPS can be customized to do this. But I am not
sure on how to proceed. Perhaps somebody can point me in the right
direction...

If you have an x86 box running Gentoo, there's the `sys-devel/crossdev` package 
for generating a wide variety of cross-compilers.  If you're running another 
distribution, you'll want to check out Dan Kegel's `crosstool` package at:

And if you're using Debian, apt-get install toolchain-source. But this is
limited to one version, right now gcc 3.4.3 and binutils 2.15. If you need a
different version, fall back to crosstool.
