[FFmpeg-user] Unable to compile(configure failed) ffmpeg on Ubuntu20.04

[玄原]

Hello all,


I'm not able to compile ffmpeg(4.1.6 or 4.4.4) on Ubuntu20.04.


It is failed at the configuration stage which I'm not expected since I have done the same successfully on ubuntu18.04 many times.


Have stuck on this some days, please give me some help.


Details:
There is assembler error in the config.log which I not sure whether this matter or not. 
I can see the the nasm is there.
root at user:/var/backups/workwork/ffmpeg-4.4.4/ffbuild# nasm --version
NASM version 2.14.02



I have installed all dependency following: https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

The command I used:  ./configure --prefix=/usr/local/ --enable-gpl --enable-nonfree  --enable-libx264   --enable-libx265 --enable-debug --disable-optimizations --enable-shared --enable-pthreads   --enable-network --enable-pic  --disable-x86asm --disable-asm --disable-symver --disable-devices --disable-avdevice --disable-ffplay


Attached the config.log.


Thanks,
Beffery
