Won't build on Ubuntu 15.10 #29

Closed bfishman closed 8 years ago

bfishman commented 8 years ago

Hello!

Build is failing in multiple places. I'm trying to fix by manually installing libs, etc, and have made 2 changes so far, but as a result I don't have the exact error messages from those earlier failures (don't really feel like re-downloading chromium on my current internet connection!) - so I'm going to paraphrase.

Error 1: missing .../third_party/icu/icu.gyp. The entire icu directory is missing. I pulled it from an earlier branch of chromium and put it in the expected location, which seems to have resolved the error message.

Error 2:
missing libvpx_new/libvpx.gyp Can't remember the exact details, but same idea - no libvpx_new folder was present. I also manually tried to install this, but am probably using the wrong version (I grabbed one from a day prior to your last commit ~26 October). Likely, that's the source of my current error:

Error 3: I haven't been able to fix this yet: ninja: error: '../../third_party/libvpx_new/source/libvpx/vp9/encoder/x86/vp9_error_intrin_avx2.c', needed by obj/third_party/libvpx_new/source/libvpx/vp9/encoder/x86/libvpx_intrinsics_avx2.vp9_error_intrin_avx2.o', missing and no known rule to make it

I read in another (closed) issue that you're planning to update to the latest WebRTC build. I'm looking forward to that, and thank you for your efforts!

Hi,

I have updated the code to the latest WebRTC branch but my Tux box is down for now. So i'cant create prebuilt modules. Let me know if it worked? Btw there is so much changes, and therefore it is better to remove whole webrtc-native and rebuild it.

Thanks!

Hello @vmolsa !

Thank you for the update. Unfortunately the build failed. I received a warning, then an outright failure:

The warning:

It looks like I'm missing some C++ libraries. I did install the prerequisites you have listed on the front page:

sudo apt-get install --yes build-essential python2.7 git pkg-config libnss3-dev libasound2-dev libpulse-dev libjpeg62-dev libxv-dev libgtk2.0-dev libexpat1-dev default-jdk libxtst-dev libxss-dev libpci-dev libgconf2-dev libgnome-keyring-dev libudev-dev

EDIT: I don't think it should matter, but I'm running Ubuntu 15.10. Will update the issue's title. I'm actually running lubuntu, which I thought was built off the LTS, aparently it's not.

More info:

c++ version 5.2.1
node version 4.3.1

I installed GCC 4.8 and set that as the default for C++, build still failed, this time with a series of errors looking like this:

ax3l commented 8 years ago

We could add a travisc-ci support for the project (Ubuntu 14.04 trusty) but I did not get it to compile either.

Here is my travis branch: https://github.com/ax3l/webrtc-native/tree/topic-addTravisCI

vmolsa commented 8 years ago

Building WebRTC takes too long for travis and thats why it's failing?

ax3l commented 8 years ago

I guess so, it's about 1 hr build time. Can we download a pre-build WebRTC somehow first?

vmolsa commented 8 years ago

For now webrtc-native is integrated with WebRTC. Splitting that webrtc part from webrtc-native requires shared library and i prefer don't do that.

ax3l commented 8 years ago

Ok I see. Is there something problematic about shared libs in our case?

alangibson commented 8 years ago

I'm also getting build failures on Ubuntu 15.04. I was able to get past the missing includes by doing this:

// Apparently needs g++ 4.8, not the included 4.9

sudo apt-get install g++-4.8 sudo rm /usr/bin/g++ sudo ln -s g++-4.8 /usr/bin/g++

// These paths are missing

export CPATH=/usr/include/c++/4.8:/usr/include/x86_64-linux-gnu/c++/4.8:/usr/include/c++/4.8/backward

// Build webrtc-native

git clone https://github.com/vmolsa/webrtc-native cd webrtc-native export BUILD_WEBRTC=true npm install

However, now I'm getting errors that I can't make much sense of: ../../../../../src/GetSources.cc: In static member function ‘static rtc::scoped_refptr<webrtc::VideoTrackInterface> WebRTC::GetSources::GetVideoSource(constrtc::scoped_refptr<WebRTC::MediaConstraints>&)’: ../../../../../src/GetSources.cc:91:26: error: ‘VideoSourceInterface’ is not a member of ‘webrtc’ rtc::scoped_refptr<webrtc::VideoSourceInterface> src = factory->CreateVideoSource(capturer, constraints->ToConstraints());

vmolsa commented 8 years ago

@alangibson Thanks!

Fixed now. I enabled clang but node versions v0.10.x and v0.12 can't to be compiled because those versions doesn't support clang. Rest of node versions have now prebuilt modules so i'm closing this one..

bfishman commented 8 years ago

Awesome, thank you! Prebuilt binaries work great on Ubuntu 15.10!
