Hi Waldemar, all,

I'm still seeing this error under Gentoo against 2017.11:

>>> systemd 234 Building

I believe on Gentoo some sort of environment leakage is breaking the lib path.

defconfig:

BR2_arm=y
BR2_cortex_a9=y
BR2_ARM_ENABLE_NEON=y
BR2_ARM_ENABLE_VFP=y
BR2_ARM_INSTRUCTIONS_THUMB2=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_INIT_SYSTEMD=y


This has been an issue for quite some time, and the reason why I have
not upgraded past the early 2017 release. I finally upgraded to 2017.11
and have found that it's once again broken compilations on my machine.

I'm not sure how to get Buildroot to produce a more verbose CCLD output,
I have tried "make VERBOSE=1" but this doesn't give me more than shown above.

I previously bisected the issue down to commit 400eaa3452 if that helps.

That commit bumped the linux headers (I believe) from 4.9.9 to 4.10.0.

Best,
Christian Stewart
