ACC conformance test FAILED

pyraohms — Mon, 07 Aug 2017 10:56:39 GMT

Trying to build my first image using Yocto. The compiler fails in the following step:

| checking whether your compiler passes the ACC conformance test... FAILED

| configure: Your compiler failed the ACC conformance test - for details see

ERROR: Task 402 (virtual:native:/home/per/fsl-release-bsp/sources/poky/meta/recipes-support/lzop/lzop_1.03.bb, do_configure) failed with exit code '1'

Can anyone offer a suggestion of how this may be solved?

Thanks

The problem can be solved by replacing the contents of <yocto>/sources/poky/meta/recipes-support/lzop/lzop/x32_abi_miniacc_h.patch with the following:

Fix get of FLAGS register in x32 ABI,

x32 ABI requires to have 64-bit variable to store FLAGS register
instead of size_t that is 32-bit variable, this fix operand
type mismatch when try to pop previous pushf value.

Above is a concatenation of the original contentes of the file with the patch found here:

It can surely be done in a nicer way, but i do not know how. This made it work for me though!
