libwebrtc's Issues

Windows: Add support for x86 architecture

Is BUILD_DEB_PACKAGE working

I tried with -DBUILD_DEB_PACKAGE=ON but it didn't created a deb package, am I doing something wrong ?

x64 build

hello,
what params to CMake to build library for windows x64? Tips from docs seems resulting error:

C:\Users\evgo\Documents\libwebrtc>cmake -G "Visual Studio 14 2015" -DTARGET_CPU=x86

CMake Error: Error: generator : Visual Studio 14 2015 Win64

Either remove the CMakeCache.txt file and CMakeFiles directory or choose a different binary directory.

Generate .deb and .rpm packages

Linux: Add support for x86 architecture

Make sure that we can compile with both CMake and Jake for x86.

Cmake fails on Windows

Hello, I'm using the current branch version, Visual Studio Community 2015 Update 3 and Windows 10 SDK (10.0.14393) as mentioned on https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md#Visual-Studio but I get still the same compile errors like juliao https://github.com/aisouard/libwebrtc/issues/29

What I'm doing wrong?

Thanks in advance.

buid_output.txt

Win32: Add 7zip package support

The WebRTC library is huge under Windows (approx. 210MB).
We can reduce the package size with 7zip (approx. 18MB).

Add 7zip rules in CMake and Jake.

Windows: Add support for Debug and Release builds

The CMAKE_BUILD_TYPE configuration variable seems to be empty under Visual Studio.

Manage depot_tools as an external project

First step for #30

Retrieve the depot_tools repository with CMake
Set the environment variable inside prefix.sh to disable auto-update
Use gclient to retrieve WebRTC with the desired commit / release branch head
Checkout depot_tools to a commit having the closest date with WebRTC's

CMake: Remove Common.cmake

We are using CMake 3.0, it's time to remove Common.cmake since we can use the cmake -E env command prefix.

Use Jake exclusively for fetching and running CMake

Static linking is finally done with CMake, we should use Jake only for retrieving prebuilt binaries and running CMake if none exists.

component has been deprecated

if you set component_build to true in a standalone libwebrtc build, it will yell at you.

There is no current supported way to compile a shared library.

RTTI not set on linux/macos build?

if you try to subclass a VideoCapturer or Thread you get

undefined reference to `typeinfo for cricket::VideoCapturer'
undefined reference to `typeinfo for rtc::Thread'

This seems to be because RTTI was not enabled in the build. It should be enabled by default for linux and macos.

-fno-rtti must be set on your app to avoid the problem. But there should at least be an option to include RTTI.

Build and run a sample under Travis and Appveyor

After running tests, continuous integration services should clone the libwebrtc-sample repository, compile it with the previously installed CMake package then run the sample to initiate a connection and check if everything has been linked properly.

CMake: Find the minimum required version

Everything is working under CMake 3.5, it might be overkill to force this version since the build scripts might work on 3.0 for instance.

Prevent Visual Studio from generating PDB files

PDB files shouldn't be generated under Release mode. Debugging info should be embedded directly inside the resulting lib file, otherwise it will output the following message during link:

webrtc.lib(webrtcsdp.obj) : warning LNK4099: PDB 'libjingle_peerconnection_cc.pdb'
  was not found with 'webrtc.lib(webrtcsdp.obj)' or at 'C:\projects\node-webrtc\build\
  Release\libjingle_peerconnection_cc.pdb'; linking object as if no debug info
  [C:\projects\node-webrtc\build\webrtc.vcxproj]

Clone submodules if depot tools can't be found

The build process just stops when it can't find depot tools.

You might not want to pass -j to ninja

it is internally multithreaded and is doing a good job at finding the maximum number of thread.
Passing -j should then only be used to reduce the number of thread ninja would normally use, in case you are using the computer to do something else. Any number passed above the optimal number would result in decreased performance. The -j option is dangerous ...

Add all possible environments in Travis

x86, x64, Debug and Release
I'll see about ARM later.

Build problems due to ABI macros

Hi,

I'm getting some issues when I try to build webrtc libraries and peer connection example with my code.

This is an example:

CMakeFiles/window_manager.dir/src/startingWindow.cpp.o: In function `std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > cricket::VectorToString<cricket::AudioCodec>(std::vector<cricket::AudioCodec, std::allocator<cricket::AudioCodec> > const&)':
startingWindow.cpp:(.text+0x1d41): undefined reference to `cricket::AudioCodec::ToString[abi:cxx11]() const'
CMakeFiles/window_manager.dir/src/startingWindow.cpp.o: In function`std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > cricket::VectorToString<webrtc::RtpExtension>(std::vector<webrtc::RtpExtension, std::allocator<webrtc::RtpExtension> > const&)':
startingWindow.cpp:(.text+0x1edb): undefined reference to `webrtc::RtpExtension::ToString[abi:cxx11]() const'
CMakeFiles/window_manager.dir/src/startingWindow.cpp.o: In function`std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > cricket::VectorToString<cricket::DataCodec>(std::vector<cricket::DataCodec, std::allocator<cricket::DataCodec> > const&)':
startingWindow.cpp:(.text+0x2075): undefined reference to `cricket::DataCodec::ToString[abi:cxx11]() const'
collect2: error: ld returned 1 exit status

I've google it and it is due to changes between different versions of c++ libraries.

Also, I've seen that libwebrtc defines ABI macro = 0 so, if I didn't missunderstand, it uses old version of ABI macros.

Is there any way to build this libraries with ABI = 1?

Thanks

Issue building c project with LibWebRTC

Hi,

I'm working with WebRTC on Ubuntu 16.04, installed as you explain.

My problem is when I try to build client peerconnection with cmake, I get:

webrtcbridge_node.cc:(.text+0x41): undefined reference to `gtk_init'
webrtcbridge_node.cc:(.text+0xee): undefined reference to `GtkMainWnd::GtkMainWnd(char const*, > int, bool, bool)'

webrtcbridge_node.cc:(.text+0x2d8): undefined reference to `GtkMainWnd::~GtkMainWnd()'

This is my CMakeLists.txt

cmake_minimum_required(VERSION 3.3)
project(webrtcbridge)

add_compile_options(-std=c++11)

find_package(LibWebRTC REQUIRED)
include (${LIBWEBRTC_USE_FILE})

find_package(PkgConfig REQUIRED) 
pkg_check_modules(GTK3 REQUIRED gtk+-3.0)

include_directories(${GTK3_INCLUDE_DIRS})
link_directories(${GTK3_LIBRARY_DIRS})

add_executable(${PROJECT_NAME}_node src/webrtcbridge_node.cc)

target_link_libraries(${PROJECT_NAME}_node
  ${LIBWEBRTC_LIBRARIES}
)

target_link_libraries(${PROJECT_NAME}_node
  ${GTK_LIBRARIES}
)

Trying to find out where is the problem, I've tried to build with gcc, and when I use pkg-config with LibWebRTC, it returns this error:

Error: -lwebrtc not found (which is in pkg-config --libs) and I dont know exactly how to fix this.

Any idea? Thanks

Call find_package macros in the main CMakeLists.txt file

find_package macros are called inside the UseLibWebRTC.cmake file, which is bad since the system will require these packages before compiling the library

Generate a Framework for macOS

Would be nice to have for our friends using Xcode.

libwebrtc.a missing some classes

linux 64bit, ubuntu 14.04 lts
I tried to link webrtc-streamer with libwebrtc.a and I had to provide following to linked to succeed:
/usr/local/src/libwebrtc/out/webrtc/src/out/Release/obj/webrtc/system_wrappers/libmetrics_default.a
/usr/local/src/libwebrtc/out/webrtc/src/out/Release/obj/webrtc/system_wrappers/field_trial_default/field_trial_default.o
Looks this also should go into lib.

Failed to fetch file gs://chromium-clang-format

It's happening more frequently with Travis under macOS.
Perhaps it doesn't like fetching multiple binaries in parallel ?

Write FindLibWebRTC.cmake module

This CMake module will find the libWebRTC include and library paths.

Remove Chromium dependencies

Latest WebRTC revisions don't need to retrieve Chromium dependencies anymore, that's wonderful!
However, we still need to provide gn and clang_format binaries inside WebRTC's buildtools folder.

Support older WebRTC releases

As discussed in #29, older releases using dependencies from the Chromium repository must be supported.

It should be done in two parts:

Execute sync_chromium.py and setup_links.py scripts when they are present. It will take a long time to download (approx. 40 minutes), but it will fix the issue quickly before doing the second part.
Bring the libwebrtc-chromium-deps repository back, the classic way. It will only contain the necessary files to compile WebRTC with this project.

Issues compiling on OSX.

OSX: 10.12.3
Xcode: 8.2.1

During compilation i get the following two errors.

debug_dump_writer.cc:108:3: error: [chromium-style] auto variable type must not deduce to a raw pointer type.
audio_network_adaptor_impl.cc:67:8: error: [chromium-style] auto variable type must not deduce to a raw pointer type

Has anyone seen this before and might be able to recommend a fix?

Peerconnection_client example segmentation fault

Hello,
I tried to run peerconnection_client example linked with libwebrtc.a but I end up with a segmentation fault.
I am running on a Unix machine 16.04.1-Ubuntu x86_64.

After running your script, I run the attached CMakeLists.txt in a different directory :

Is it linked to Gtk deprecated functions ?
