Errors building Libsourcey with webrtc #212

Closed Biancakr closed 6 years ago

Biancakr commented 6 years ago

Hi!

I'm trying to build LibSourcey with WebRTC on a Raspberry Pi. I accomplished to build WebRTC, branch 59, on the Raspberry, by using the webrtc-build from your git. However I was not able to build LibSourcey on the Raspberry.

After this I decided to build WebRTC and Libsourcey on the PC with a Linux distibution (17.04) After building WebRTC, branch 59 through the webrtc-build, for the PC succesfully, I tried to build LibSourcey on the PC.

Howerver, when building LibSourcey I got a lot of errors. (similair to the errors of the Raspberry)

I posted a couple of the errors in the link below: https://pastebin.com/bdnXcfQr

The errors: "undefined reference to" webrtc::metrics::HistogramAdd webrtc::metrics::HistogramFactoryGetCounts webrtc::metrics::GetHistogramName are repeated over and over.

Build webrtc-build: ./build.sh -b branch-heads/59 -l jsoncpp -e -d

Build libsourcey: cmake .. -DCMAKE_BUILD_TYPE=DEBUG -DBUILD_SHARED_LIBS=OFF \ -DBUILD_APPLICATIONS=OFF -DBUILD_MODULES=OFF \ -DBUILD_SAMPLES=ON -DBUILD_TESTS=ON \ -DWITH_FFMPEG=ON -DWITH_OPENCV=OFF \ -DWITH_WEBRTC=ON -DBUILD_MODULE_archo=ON \ -DBUILD_MODULE_base=ON -DBUILD_MODULE_crypto=ON \ -DBUILD_MODULE_http=ON -DBUILD_MODULE_json=ON \ -DBUILD_MODULE_av=ON -DBUILD_MODULE_net=ON \ -DBUILD_MODULE_pacm=ON -DBUILD_MODULE_pluga=ON \ -DBUILD_MODULE_sked=ON -DBUILD_MODULE_socketio=ON \ -DBUILD_MODULE_stun=ON -DBUILD_MODULE_symple=ON \ -DBUILD_MODULE_turn=ON -DBUILD_MODULE_util=ON \ -DBUILD_MODULE_uv=ON -DBUILD_MODULE_webrtc=ON \ -DWEBRTC_ROOT_DIR=/dir/to/prebuild_webrtc

I hope you can help me solve these issues. Thanks in advance!

Hi all! Thanks for the great project! Sadly I'm getting the same errors as Biancakr when I try to compile libsourcey with my own compiled webrtc library (linking errors in the webtrcstreamer example). When I use the precompiled webrtc library it works perfectly but I need to use my own compiled webrtc library. I followed the instructions to the letter. Im on ubuntu 16.10 btw. I really hope you can help me:)

Hey guys, look like you aren't the first ones to experience this with WebRTC, check here: https://groups.google.com/forum/#!topic/discuss-webrtc/3-nnqY9TZsc

Looks like the histogram symbols are defined in: system_ wrappers/field_trial_default/field_trial_default.o

Hope this helps!

Thanks for your reply. Unfortunately, the link you provided did not solve my issue. I still receive the same errors as I did previously.

I was wondering if these errors were produced by compiling webrtc wrongly, or if LibSourcey is linking the libraries wrong, in my current configuration?

Hopefully you can help me.

Its must be to do with your compiled webrtc library since the precompiled libs are working. Are you compiling and linking with the monolythic webrtc lib (webrtc_full.a) or individual libs? Can you let me know which webrtc libs you are linking with and in which order they show up and perhaps I can help.

I am compiling and linking it to individual libraries. The architecture of my webrtc-build library files/dirs is as follow:

lib/
└── x64
    ├── Debug
    │   ├── libboringssl.a
    │   ├── libcpu_features_linux.a
    │   ├── libfield_trial_default.a
    │   ├── libjingle_peerconnection.a
    │   ├── libmetrics_default.a
    │   ├── libprotobuf_full.a
    │   ├── libprotobuf_lite.a
    │   ├── libprotoc_lib.a
    │   ├── libsystem_wrappers.a
    │   ├── libwebrtc.a
    │   └── pkgconfig
    │       └── libwebrtc_full.pc
    └── Release

        ├── libcpu_features_linux.a
        ├── libfield_trial_default.a
        ├── libjingle_peerconnection.a
        ├── libmetrics_default.a
        ├── libprotobuf_full.a
        ├── libprotobuf_lite.a

        ├── libwebrtc.a
        └── pkgconfig
            └── libwebrtc_full.pc

This architecture is automaticly provided by running the command: ./build.sh -b branch-heads/59 -l jsoncpp -e -d

When compiling LibSourcey's webrtc streamer, I used the following command:

I also tried with more libraries of webrtc:

make -f

../prebuild_webrtc/lib/x64/Release/libmetrics_default.a

../prebuild_webrtc/lib/x64/Release/libboringssl.a 
../prebuild_webrtc/lib/x64/Release/libwebrtc.a 
........

And with all of the libraries:

make -f 
....

../prebuild_webrtc/lib/x64/Release/libfield_trial_default.a

Histogram is no longer required be default in later WebRTC builds, so I'll close this for now.
