I downloaded latest version of webrtcbuilds and ran the following :

build.sh -b 50 -t linux

Because chromium/src is transitioning to Git (from SVN), we needed to
change the way that the WebRTC standalone checkout works. Instead of
individually syncing subdirectories of Chromium in SVN, we're now
syncing Chromium (and all of its DEPS, as defined by its own DEPS file),
into the `chromium/src` directory.

As such, all Chromium directories which are currently pulled by DEPS are
now replaced with a symlink into the full Chromium checkout.

To avoid disrupting developers, we've chosen to not delete your
directories forcibly, in case you have some work in progress in one of
them :).

ACTION REQUIRED:
Before running `gclient sync|runhooks` again, you must run:
src/setup_links.py --force

Which will replace all directories which now must be symlinks, after
prompting with a summary of the work-to-be-done.

Thanks, I'll try to repro for this...

running ./build.sh -b 50 -t linux with:

• a fresh clean repo (checking out branch 50 directly)
• a repo that has a pre-existing 'latest' checkout in out (checking out latest then branch 50)

one other thing comes to mind is depot_tools, what is that revision?

cd depot_tools
git log -1 --oneline

[HefnySco]

cd depot_tools
git log -1 --oneline

Repro'ed and added doing the action required (setup_links), please reopen if there's still an issue with this.

[HefnySco]

Thank you for your effort. It passed. Now I have this:

_``` ___ running '/usr/bin/python src/webrtc/build/gyp_webrtc -Dextra_gyp_flag=0' in '/mnt/vdb/webrtcbuilds/out' Updating projects from gyp files...

my original command is: 
`. build.sh -b 50 -t linux -c arm64
`

[vsimon]

From the error it looks like from the time that the branch 50 was cut, ~2016, certain ubuntu distributions existed and WebRTC internally may be checking for those distributions.

ERROR: Only Ubuntu 12.04 (precise), 14.04 (trusty), 14.10 (utopic), 15.04 (vivid) and 15.10 (wily) are currently supported

Do you happen to be using xenial (16.04)?

[HefnySco]

I downgraded the machine to ubuntu 14.04. I compiled many linux on x64 with no problems at all. still the arm64 . build.sh -b 50 -t linux -c arm64

No missing packages, and the packages are up-to-date.

I did a little digging, it appears like this bug https://bugs.chromium.org/p/chromium/issues/detail?id=568883, but it also appears from the timestamps that it was fixed before branch 50 was made.

I also tried building with linux/arm64 with latest with:

./build.sh -t linux -c arm64 # build script errors and tells to install the following script
out/src/build/linux/sysroot_scripts/install-sysroot.py --arch=arm64
./build.sh -t linux -c arm64 # continue the build

and that seemed to work. So at this point, I'm still not sure exactly why latest works and branch 50 doesn't but I'm open to ideas.

https://cs.chromium.org/chromium/src/build/install-build-deps.sh
./build/install-build-deps.sh  --no-chromeos-fonts 

$ git clone --depth 1 https://chromium.googlesource.com/chromium/tools/depot_tools.git
$ export PATH=`pwd`/depot_tools:"$PATH"

export GYP_DEFINES="target_arch=x64 host_arch=x64 build_with_chromium=0 use_openssl=0 use_gtk=0 use_x11=0 include_examples=0 include_tests=1 fastbuild=1 remove_webcore_debug_symbols=1 include_pulse_audio=0 include_internal_video_render=0 clang=1 "

mkdir webrtc-checkout
cd webrtc-checkout

gclient config https://chromium.googlesource.com/external/webrtc.git@branch-heads/50 --name=src
gclient sync --force --with_branch_heads 
gclient sync --force --with_branch_heads --nohooks 

cd src

git checkout branch-heads/50

gclient runhooks 

ninja -C ./out/Release 

These are the exact steps that build branch 50 with no problems at all.

[vsimon]

Thanks for the steps. I see branch 50 builds with target_arch=x64 with no problems at all. I notice this didn't set the target arch to arm64 which is what the -c arm64 argument would do. I wasn't able to build further with these steps with target_arch=arm64 set in the GYP_DEFINES export, have you?

Like:

export GYP_DEFINES="target_arch=arm64 host_arch=x64 build_with_chromium=0 use_openssl=0 use_gtk=0 use_x11=0 include_examples=0 include_tests=1 fastbuild=1 remove_webcore_debug_symbols=1 include_pulse_audio=0 include_internal_video_render=0 clang=1 "

[HefnySco]

When I run

. build.sh -b 50 -t linux 

I got

ERROR: Only Ubuntu 12.04 (precise), 14.04 (trusty),  14.10 (utopic), 15.04 (vivid) and 15.10 (wily) 
/mnt/disks/webrtcbuilds/out/src/build/install-build-deps.sh: line 80: are currently supported: command not found

I was never able to build branch 50 using build.sh :(
