Issues compilling SDDM

I'm currently trying to install SDDM (I'm currently using SLiM, but on my laptop I'm currently changing over to Wayland, which SLiM dosn't seem to support). However Portage gets stuck and says "Incompatible processor. This Qt build requires the following features: aes", I also tried installing qtwayland earlier which had the exact same issue. My laptops CPU is a Celeron N2940 which according to https://en.wikipedia.org/wiki/AES_instruction_set#Intel my CPU does support the instruction (it's a Silvermont CPU).

How should I try and fix this? I was thinking of somehow conving the software that my CPU is supported or somehow to force it to compile anyway, but I'm not really sure how to do either.

You use -march=native? If yes what return command gcc -march=native -E -v - </dev/null 2>&1 | grep cc1?

I'm using -march=silvermont because I also recently setup distcc with my desktop and laptop. I also stopped distccd so it's not an issue with distcc.

Heres the output from that command:

Try to compile with -march=native I suspect that -march=silvermont add -maes and your cpu not support it

According to this new aes instruction set is not supported by this CPU.

Actually I made a mistake, just to be sure, I read up more on specifically the Silvermont Bay Trail-M and Trail-D processors and it turns out my CPU is a Tail-M CPU! So it dosn't actually support aes.

So, in that case, does anybody know how I would still install SDDM anyway? Or am I just out of luck? It's still a fairly recent CPU so I would think that the software should be able to compile without that instruction to support some of the older CPUs

Nope, it dosn't look like compilling with march=native worked.

Please post the exact emerge command you executed and the error output it produced.

The build.log output is truncated, you can post full build.log?

It looks like dev-qt/qtdbus owns the program that aborts. If you are sure that your CPU is supported, you should investigate that package to find why it disagrees with you.
