Hi, I read README-win-linux.md and I installed following packages:

sudo apt-get -y install \
        gcc make perl \
        autoconf \
        automake \
        build-essential \

Do you have any idea where pthread need to be enabled? Thank you.

[PhilLAL]

I forgot to notify @mi-g My apologies if unnecessary. :)

[PhilLAL]

does anyone have any idea how to solve this? Did I miss some obvious config or instruction? Cheers

[mi-g]

I just released version 1.6.0. Build scripts have been updated and now compiles on Ubuntu 16.04, Ubuntu 18.04 and 20.02. Note that you will have to re-run the script get-sources.sh

Closing this bug. Please reopen if needed

[PhilLAL]

Sorry, but I can't reopen this issue.

When running ./build-apps.sh I got following output:

On what system are you compiling ? This works well for me on clean installs of Ubuntu 16.04, 18.04 and 20.04 with installed compilation packages as described in the readme file. Some assembly code requires either yasm or nasm. I always used yasm. Maybe the problem is if you are using nasm.

[PhilLAL]

Thank you. I build it on debian 10, with yasm package installed.

Last lines make me read converter/src/vpx/build/make/Makefile on line 158 It is last line of

Compiling ffmpeg and the 18 associated libraries is tricky and very dependent on the compilation tools. In my setup i use ubuntu 16.04 (for glibc 2.23) and 18.04 virtual machines (server installs as there is no need for a user interface) on VirtualBox dedicated to compiling the coapp. I suggest you do the same, as tracking why it does not work in a specific would be an endless tedious job :)
