[SOLVED] KDE don't start. Incompatible processor. This Qt build requires the following features: aes

Question

HI.

i have problems with AES FLAG.
i installed funtoo on a samsung laptop with Core i3 Westmere.

i used intel64-westmere stage3.

but when i installed KDE desktop  refuses to init because:

# nano /var/lib/sddm/.local/share/sddm/xorg-session.log


Incompatible processor. This Qt build requires the following features: 
aes 
Aborted. Incompatible processor: missing feature 0x2000000 - aes.

 

my processor is westmere but do not support aes.

 # gcc -march=native -E -v - </dev/null 2>&1 | grep cc1 
 /usr/libexec/gcc/x86_64-pc-linux-gnu/7.3.1/cc1 -E -quiet -v - -march=westmere -mmmx -mno-3dnow -msse -msse2 -msse3 -mssse3 -mno-sse4a -mcx16 -msahf -mno-movbe -mno-aes -mno-sha -mno-pclmul -mpopcnt -mno-abm -mno-lwp -mno-fma -mno-fma4 -mno-xop -mno-bmi -mno-sgx -mno-bmi2 -mno-tbm -mno-avx -mno-avx2 -msse4.2 -msse4.1 -mno-lzcnt -mno-rtm -mno-hle -mno-rdrnd -mno-f16c -mno-fsgsbase -mno-rdseed -mno-prfchw -mno-adx -mfxsr -mno-xsave -mno-xsaveopt -mno-avx512f -mno-avx512er -mno-avx512cd -mno-avx512pf -mno-prefetchwt1 -mno-clflushopt -mno-xsavec -mno-xsaves -mno-avx512dq -mno-avx512bw -mno-avx512vl -mno-avx512ifma -mno-avx512vbmi -mno-avx5124fmaps -mno-avx5124vnniw -mno-clwb -mno-mwaitx -mno-clzero -mno-pku -mno-rdpid --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=3072 -mtune=westmere

 

so i changed in /etc/portage/make.conf


CFLAGS="-march=native -mno-aes -O2 -pipe"
CXXFLAGS="${CFLAGS}"
FFLAGS="${CFLAGS}"
FCFLAGS="${CFLAGS}"
USE="-aes"

then

emerge -ave @system

Now works, i hope this help someone.
