[U-Boot] Recommended MIPS toolchain

[Vasili Galka]

Hi,

What is the recommended tool-chain to verify compilation of MIPS boards?

I tried the one from
https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/
But it does not work, throws plenty of errors about hard/soft float.

Regards,
Vasili

you could try

Denx ELDK 5.5 for MIPS
http://www.denx.de/wiki/ELDK-5/WebHome

or

Mentor Sourcery CodeBench Lite Edition for MIPS ELF
https://sourcery.mentor.com/GNUToolchain/subscription3537?lite=MIPS

Similar to ARM you can use the built-in libgcc implementation of U-Boot
with "export USE_PRIVATE_LIBGCC=yes" (before Kbuild/Kconfig) or
"CONFIG_USE_PRIVATE_LIBGCC=y".

Actually you would need a full multilib toolchain with different libgcc
or multiple toolchains to build all BE/LE and hard-float/soft-float
variants. But that is not feasible, so you should always set
USE_PRIVATE_LIBGCC. USE_PRIVATE_LIBGCC is also required for ELDK toolchains.

BTW: "MAKEALL -a mips" with the kernel.org toolchain and
USE_PRIVATE_LIBGCC works

Strangely, I still fail to build.
I'm trying on u-boot/master 6d1966e12 (dated Aug 1st 2014)
Building with the following commands, on clean build directory:

export BUILD_DIR=/home/lab/dev/u-boot/out/all_mips
export USE_PRIVATE_LIBGCC=yes
export CROSS_COMPILE=mips-linux-
./MAKEALL -a mips

Here is what I get with the toolchain from kernel.org:

sorry if I was not accurate enough but with introduction of Kbuild
"USE_PRIVATE_LIBGCC=yes" was changed to "CONFIG_USE_PRIVATE_LIBGCC=y".
To support different U-Boot versions you should set both variants:

export USE_PRIVATE_LIBGCC=yes
export CONFIG_USE_PRIVATE_LIBGCC=y

My sincere apologies. My mistake. Your explanation was fine - I just misread it.
Anyway, I have just successfully built all the boards with the
kernel.org tool-chain.

Many thanks for the help!

Shall I send a patch to enable CONFIG_USE_PRIVATE_LIBGCC ?

That probably depends on the percentage of toolchains that require this
flag to be set. I only tried one and it does require it. I believe Daniel
can provide more statistics.

I'm not sure. That would change the behaviour of MIPS in relation to
other architectures. I think we need a common solution for all
architectures which always use a private libgcc like the kernel does.
