[Buildroot] Incorrect ABI setting on ubuntu 14.04LTS

[Buildroot] Incorrect ABI setting on ubuntu 14.04LTS

[Marco Pastorelli]

Hi everybody,

I'm using buildroot 2014.05 to compile a BSP for a beaglebone. I'm using
linaro toolchain 2014.02

If I compile with ubuntu 12.04LTS everything works fine.
When I compile exactly the same project with another PC running ubuntu
14.04LTS I run into this error:

>>> toolchain-external undefined Configuring
Incorrect ABI setting: EABIhf selected, but toolchain is incompatible

Does anybody knows which could be the problem?

Thanks!
Marco.

What is the output of:

echo 'int main(void) {}' | arm-linux-gnueabihf-gcc -x c -o /dev/null

on the problematic machine?

Forgot a dash. The command should be:

echo 'int main(void) {}' | arm-linux-gnueabihf-gcc -x c -o /dev/null -

You should maybe indicate that this has to be done with the
arm-linux-gnueabihf-gcc compiler downloaded and installed by Buildroot,
so:

	./output/host/opt/ext-toolchain/bin/arm-linux-gnueabihf-gcc

I guess your host lacks a 32bit version of libz. Try installing the ia32-libs 
package.

apt-get install zlib1g:i386

is what you need.

I think we need to add a check for this to tell the user in a clearer
way.

I'm afraid Ubuntu 10.04 was not multi-arch enabled. That's why I suggested 
ia32-libs instead.

Marco reported using 14.04 LTS.

Right, of course. Sorry for the noise.

Related to this: why do we redirect stderr of the compiler invocation to 
/dev/null in check_arm_abi? We are not interested in the output itself as we 
only check whether the compiler runs successfully. When the test succeeds it 
should not output anything. Whereas in the failing case the output is very 
interesting.

Indeed, would make sense to not redirect stderr to give more clue to
the user about what's going on.
