Undefined symbols for architecture x86_64 #69

BeiKeJieDeLiuLangMao commented 6 years ago

I am a new bee for c++, i build libwebrtc in my mac, change PKG_CONFIG_PATH to be /path/to/libwebrtc/out, and change LibWebRTC.pc like follow

prefix=/usr/local
exec_prefix=${prefix}
libdir=/path/to/libwebrtc/out/lib
includedir=/path/to/libwebrtc/out/include

Name: LibWebRTC
Description: Google's native WebRTC implementation shipped into a single library
Version: 0.0.1-rc.4
Libs: -L/path/to//libwebrtc/out/lib -lwebrtc
Libs.private: -L/System/Library/Frameworks AudioToolbox CoreAudio CoreFoundation CoreGraphics Foundation
Cflags: -I${includedir} -DWEBRTC_POSIX -D_GLIBCXX_USE_CXX11_ABI=0 -std=gnu++0x

But when i execute this command to run your sample, a error happened. $ g++pkg-config --cflags LibWebRTCmain.cpp -o mainpkg-config --libs LibWebRTC``

Did i make a mistake with LibWebRTC.pc or maybe others?

Reduced the previous undefined symbol list to:

By adding the following lines to the CMakeLists.txt:

  find_library(CORE_FOUNDATION CoreFoundation)
  find_library(APPLICATION_SERVICES ApplicationServices)
  find_library(CORE_SERVICES CoreServices)

  set(EXTRA_LIBS ${CORE_FOUNDATION} ${APPLICATION_SERVICES} ${CORE_SERVICES})

Still looking at it

jmillan commented 5 years ago

Finally linked by:

  find_library(CORE_FOUNDATION Foundation)
  find_library(APPLICATION_SERVICES ApplicationServices)
  find_library(CORE_SERVICES CoreServices)

  set(EXTRA_LIBS ${CORE_FOUNDATION} ${APPLICATION_SERVICES} ${CORE_SERVICES})
hkirat commented 3 years ago

@jmillan could you elaborate on where you had to add the CMakeLists.txt file? Was it the webrc/src folder? Or inside the project where you were trying to use webrtc?

jmillan commented 3 years ago

@hkirat,

In the project where I was using webrtc.
