ndnrtc_ubuntu_quick_test

build-process.md

this is the working version for Zhehao based on Jiachen's image. May or may not work for others, or have runtime errors as it's being tested

Please compile webrtc, openfec, boost, ndn-cpp and other dependencies before moving to this

NDN-CPP-0.7

(without boost:: specification for int64_t definition as in Jiachne's version; Unverified for now.)

./configure --with-std-shared-ptr=no --with-std-function=no --with-boost-libdir=/home/jcw/boost_1_54_0/build/lib --prefix=$(pwd)/build
make
make install

NDN-RTC

in CPP folder,

./configure —prefix=$(pwd)/build

make

For now, replace the second last step of make, which generates libndnrtc.so (the command with "gcc -shared") with

In the webrtc linked libs, following libraries are newly added; since without them -lndnrtc in the app would complain about undefined symbols from webrtc; -l them when compiling the app would probably result in duplicated symbols:

-lremote_bitrate_estimator -lvideo_capture -lrtc_base -lgtest -ljsoncpp -lred -lfield_trial -lopenmax_dl

While other webrtc static libraries are manually included in -Wl,--whole-archive ... -Wl,--no-whole-archive; check configure.ac for correct flags for shared object generation.

The application (Code attached)

g++ -std=c++11 test_ndnrtc_getversion.cpp -o test_getversion -L. -lndn-cpp -L/home/jcw/ndn-cpp-zhehao/build/lib -I/home/jcw/ndn-cpp-zhehao/build/include -lndnrtc -lX11 -lXdamage -lXrender -lXext -lnss3 -lssl3 -lXfixes -lXcomposite 2>&1

Following links are added because of undefined symbol from NDN-RTC; these were probably dynamic linked by webrtc; found their symbols by nm'ing the libraries in system directory.

-lX11 -lXdamage -lXrender -lXext -lnss3 -lssl3 -lXfixes -lXcomposite

With these the app compiled successfully;

Expect to see a ndnrtc-startup.log in the same folder where you run the app.

No. 1 problem we had would be using a shared object that links to static libraries; Then just resolving further undefined symbols as needed.

Worth mentioning that this is the expected behavior on Linux: This question, and other ones from similar topic, helped.

My suspect is that on OSX it's either taken care of by XCode/build systems; Or a different ld program strategy?

test_ndnrtc_getversion.cpp

#include <iostream>
