Yocto dizzy version 1.7.1 cross compiling meta-toolchain BROKEN for weeks now!

Yocto dizzy version 1.7.1 cross compiling meta-toolchain BROKEN for weeks now!

[ad me]

[-- Attachment #1: Type: text/plain, Size: 6583 bytes --]

All,

We have been observing this bug for many weeks now, hoping the dizzy build
will be updated to fix this. It looks like it is not getting any attention.
Please help!
Any quick solution while waiting for a git repository fix?

There is a problem with this “dizzy” toolchain. though the environment
above shows this board used hard-float VFP, it looks like soft float is
used somewhere and __ARM_PCS_VFP is not defined.

Here is the version of gcc set up by the environment above:

If you go to , you will notice that it is checking for “#if !defined
__ARM_PCS_VFP”.

This somehow is not defined.

Even when I try to hack it by putting “#define  __ARM_PCS_VFP 1” at the top
of my , I get the linker error below, which implies intermediate files were
built with __ARM_PCS_VFP not defined.

You probably aren't invoking the compiler with the set of command-line
options you need to get the desired output.  See the definition of the
CC environment variable in the environment-setup script in the SDK, and
make sure you use the same set of flags to invoke gcc.

Please see the step by step in the document attached/linked.
The same one you highlighted on.

I source this script just before invoking the compiler. Which means the CC
parameters are passed in as shown.

Unless if you are suggesting that doing a "source" of the environment
script is not enough?

If so, then I would not be able to invoke the correct compiler as the PATH
to it is setup by the same environment script I source.

Sourcing the environment script is not enough; as I said, you have to
run the compiler with the right set of options.

So instead of:

arm-poky-linux-gnueabi-gcc hello_arm_world.c

You could do:

$CC hello_arm_world.c

to use the CC environment variable directly to invoke the compiler
with the options you need.

Matt,

Thanks!
I overlooked the fact that the compiler is also part of the $CC variable.

Correct usage:

---------------------------------------------------

aseema@en4078926linux:~/myyocto/fsl-community-bsp/build/tmp/sysroots/wandboard-dual/home/xuser$
./a.out
bash: ./a.out: cannot execute binary file: Exec format error
aseema@en4078926linux
:~/myyocto/fsl-community-bsp/build/tmp/sysroots/wandboard-dual/home/xuser$

-----------------------------------------------------
Obviously not an x86 executable :)

Thanks a million for pointer!
Ad.

That was a good remark. I just checked a Makefile I've written for a 
customer project, here's how I use gcc for the cross-compiled recipe:

CC=$(CROSS_COMPILE)gcc

This works for me both in Yocto builds and during stand-alone 
development with "whatever cross-toolchain is around".

Nikolay
