iOS build failed, errors like "class type 'cricket::FakeDtlsTransport'"

[andreasunterhuber]

Based on #514 (comment) there are several errors that stop building for iOS.

Changes go back to commit open-webrtc-toolkit/owt-deps-webrtc@535f946 from @taste1981

@taste1981 can you have a look?

Build details

• latest master
• building on macOS BigSur
• Xcode 12.5
• command we did run: python3 scripts/build.py

Error

Called by the build.py script in this area:

# Run unit tests on simulator. Return True if all tests are passed.
def runtest(ssl_root):
  print('Start running unit tests.')
  # Build app targets checks link issue.
  if not ninjabuild(TEST_ARCH, TEST_SCHEME, SDK_TARGETS + APP_TARGETS + TEST_TARGETS):

        getsdkversion(), '%s.app'%test_target],
        cwd=getoutputpath(TEST_ARCH, TEST_SCHEME)):
      return False
  return True

Thanks for reporting this issue. It was introduced by open-webrtc-toolkit/owt-deps-webrtc#137. I'm working on a fix.
