build failed for openwebrtc (Step 4)

[weidezhang]

I'm trying to build the openwebrtc following the instructions: https://github.com/EricssonResearch/openwebrtc/wiki/Building-OpenWebRTC Step 1~3 were successful. For step 3, I used: ./build-all.sh -Cbr osx ios ios-simulator because I'm planning to try it on an ios-simulator.

At step 4: build OpenWebRTC when I run the following command: ./build.sh -Cbr osx I tried several times with different machines (Yosemite). And I kept getting the following error message:

ld: warning: could not create compact unwind for _ffi_call_unix64: does not use RBP or RSP based frame GISCAN Owr-0.1.gir dyld: Symbol not found: _g_settings_schema_get_key Referenced from: /Users/wezhan/Documents/qiong/openwebrtc/build/x86_64-apple-darwin/owr/.libs/libopenwebrtc.3601.dylib Expected in: flat namespace in /Users/wezhan/Documents/qiong/openwebrtc/build/x86_64-apple-darwin/owr/.libs/libopenwebrtc.3601.dylib Command '['/Users/wezhan/Documents/qiong/openwebrtc/build/x86_64-apple-darwin/owr/tmp-introspectROADiA/Owr-0.1', '--introspect-dump=/Users/wezhan/Documents/qiong/openwebrtc/build/x86_64-apple-darwin/owr/tmp-introspectROADiA/functions.txt,/Users/wezhan/Documents/qiong/openwebrtc/build/x86_64-apple-darwin/owr/tmp-introspectROADiA/dump.xml']' returned non-zero exit status -5

Can you help me to solve this problem? Thanks!

I think we need to update and fix libopenwebrtc.exp. I'll look into that on Monday.

I'm having some issues as well, everything built correctly up to this stage... but I'm seeing these errors:

PR #194 should fix that last

[sdroege]

Those bits are fixed now, and the missing symbol should be fixed by https://github.com/EricssonResearch/openwebrtc/commit/0d3fcc84ae8622c487a3364dd2157ee145572c38

Let's reopen if you guys still have problems.

[EvilTrev]

I've done a complete update of the dependencies, openwebrtc and rebuilt it all from scratch... I'm seeing this error now:

It looks like the libnice GStreamer plugin is missing. Can you run:

V=1 ./build.sh -Cbr osx

And check if there is a libgstnice.a in your openwebrtc-deps-*/lib directory?

[mlakkadshaw]

@superdump I tried running using V=1 ./build.sh -Cbr osx, still same error. I checked, libgstnice.a is present under lib/gstreamer-1.0/libgstnice.a

[EvilTrev]

I also have that lib file present. Side note, and not terribly important to this particular issue... but the build won't start if you have a space ("My Projects" for example) in your folder structure.

[superdump]

@mlakkadshaw - Can you paste the output of that V=1 ./build.sh -Cbr osx build? It displays more information about the actual commands that are run which will help me with debugging. If libgstnice.a is present in your openwebrtc-deps-*/lib/gstreamer-1.0 directory, it may be that somehow a library search path has gone missing in the build script or something.

[sdroege]

The libnice problem should be fixed already by https://github.com/EricssonResearch/openwebrtc-build-scripts/commit/9fe9423288aa857de4d8d7827575435b835e5613 Try rebuilding libnice with the latest build scripts

[mlakkadshaw]

I pulled the latest scripts, and rebuild libnice, still getting the same error. Here is the output of V=1 ./build.sh -Cbr osx https://gist.github.com/mlakkadshaw/5724657eeba90197ed4e

[EvilTrev]

I just deleted everything, pulled it all again and rebuilt from scratch... I'm still not able to get past this issue:

Any thoughts? Below is the complete gist from a V1 build...

https://gist.github.com/EvilTrev/eeca8ba3a6a24d9ef7ad

[superdump]

cd scripts
git checkout master
git pull --rebase
cd dependencies
rm -rf openwebrtc-deps-*
./build-libnice.sh -Cbr osx && ./create_file_release.sh osx && ./deploy_deps.sh
cd ../..
./build.sh -Cbr osx

[EvilTrev]

That got it. Thank you
