问题
I have an iOS app (not made with xcode) and I need to include in it a dynamic library. I have this library on my computer:
\webrtc
\WebRTC.framework
\Headers
\*.h
\Modules
\module.modulemap
\WebRTC
\Info.plist
and I deploy those files inside my app like this :
ALLiveVideoChatClient.app
\Frameworks
\WebRTC.framework
\Headers
\*.h
\Modules
\module.modulemap
\WebRTC
\Info.plist
when I do
otool -L ALLiveVideoChatClient.app/ALLiveVideoChatClient
it's return me:
@rpath/WebRTC.framework/WebRTC (compatibility version 0.0.0, current version 0.0.0)
and when I try to run my app I receive the error:
Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Exception Note: EXC_CORPSE_NOTIFY Termination Description: DYLD, Library not loaded: @rpath/WebRTC.framework/WebRTC | Referenced from: /var/containers/Bundle/Application/A2C3A7DA-D35E-4649-AEA0-9AB518E48971/ALLiveVideoChatClient.app/ALLiveVideoChatClient | Reason: image not found Triggered by Thread: 0
so I check the value of @rpath doing
otool -l ALLiveVideoChatClient.app/ALLiveVideoChatClient
it returns me
cmd LC_RPATH
cmdsize 32
path $ORIGIN (offset 12)
I m not sure what mean $ORIGIN
but seam it's point to ALLiveVideoChatClient.app
so i update the @rpath to point to $ORIGIN/Frameworks
adding -rpath $ORIGIN/Frameworks
to the linker (http://www.manpagez.com/man/1/ld/) but i still receive the error image not found
What I did wrong? What are the steps to manually add (so without xcode) a dynamic library to an iOS app?
回答1:
WebRTC.framework is an embedded framework and you need to embed it with your app. If not, you will get above mentioned error.
To embed, go to build settings. You will find a section on "Embed Frameworks". Click on + icon. It will show you list of frameworks you have included in your app, select WebRTC framework. More details here Apple TechNote - Embedding Frameworks In An App
On a side note, I find Google decision to remove static library target from WebRTC absurd. We have modified build.gn(s) to generate static library and using it instead. If you need, I can share it.
