6 years ago It looks like the 4.2. Building WebRTC native-code library procedure is missing during the procedure in the README_build document.
The meaning of the log message is you are trying to compile to x86_64 binary with arm cross compiler .

commented
6 years ago I followed 4.2 and built successfully (i think anyway). I used webrtc_armv6_build_args.gn for the pi zero.
Any idea what would the make command be getting x86_64 instead of armv6?
kclyu
commented
6 years ago The makefile in rws use the build options of webrtc native code package. Since webrtc native build is for x86_64, rws is supposed to use that option in the makefile.

commented
6 years ago Okay I’ll try rebuilding again. Where can I find the build options for webrtc? I assumed they were in webrtc_armv6_build_args.gn.
Is there anyway I can check the architecture post build?
kclyu
commented
6 years ago The args.gn file is used as the build configuration file for the webrtc native code package when it builds. There is no way to check the build target after the build of webrtc but we can only verify that the compiler options during the the webrtc native code package building.

commented
6 years ago Okay thanks. I’ll repost the output with flags when I re-build (in a couple hours).

commented
6 years ago Looks like you need to copy webrtc_armv6_build_args.gn to args.gn?
I copied the README as is, ie
cp ~/Workspace/rpi-webrtc-stremer/misc/webrtc_arm_build_args.gn arm_buildShould be?
cp ~/Workspace/rpi-webrtc-stremer/misc/webrtc_arm_build_args.gn arm_build/args.gnBuilding webrtc now, will let you know how it goes.

commented
6 years ago Almost there, running into a different build issue now. I had started this process ages ago, is it possible my webrtc pull is older than your latest master branch? Again, thanks for the help!

6 years ago First of all, there is a problem with the PI.cmake file of rpi_rootfs. When upgrading to libwebsocket 3.0, the option has been enabled and the armv7 option has been added on libwebsockets
Comment out add_compile_option from the rpi_rootfs/PI.cmake file as shown below, and please completely erase libwebsockets and recompile and rebuild rws .
add_definitions("-DBOOST_COROUTINES_NO_DEPRECATION_WARNING")
#add_compile_options(-mfpu=neon-vfpv4 -mfloat-abi=hard -funsafe-math-optimizations)awesome, got it all working! Thanks for all your help and patience.
I had looked for -mfpu flags, but only on the rpi-webrtc-streamer build.
Thanks again!
I'm running into the following compile error when running make on
rpi-web-streamer:Full output
Any ideas? Likely unrelated, but the only difference I did than your doc was needing to add the following directory link to get websockets to build:
Thanks! Justin
