How to use msquic and webrtc at the same time?

[FH0]

My application use webrtc and msquic at the same time. It has webrtc directory, quic directory and main.cpp. I can't finish compiling because webrtc using boringssl and msquic using openssl, boringssl and openssl having many same export symbols.

I know --exclude-libs ALL flag. But it works for shared library. I need to compile my application statically.

I don't know if there is any solution to try to statically link both boringssl and openssl into the same process. BoringSSL was forked from openssl some time ago, that's why they're so similar. Perhaps @wfurt has some ideas, but otherwise it's likely a question beyond the scope of this project.

AFAIK you can compile libmsquic and link OpenSSL statically instead of using system crypto. Then it would not have the symbols exported. But then you cannot link your app statically.
I think the only good solution IMHO is to either make webrtc work with OpenSSL or MsQuic with BoringSsl. Since they share same origin it may not be that hard.

Finally solved by objcopy. Only prefix with msquic|quic symbols are exported.

	mkdir -p ./dep/msquic/$(TARGET)
	sed -i 's|\(^ *msquic_lib\)$$|\1 ALL|g' ./dep/msquic/src/bin/CMakeLists.txt
	cmake -B./dep/msquic/$(TARGET) -S./dep/msquic -DQUIC_BUILD_SHARED=OFF -DCMAKE_TARGET_ARCHITECTURE=$(TARGET_CPU)
	make -C./dep/msquic/$(TARGET) -j$(shell nproc)
	$(eval renameSymbols=$(shell objdump -t ./dep/msquic/$(TARGET)/bin/Release/libmsquic.a | awk -v RS= '/_YB80VJ/{next}1' | grep -E 'g +F .text' | grep -Evi ' (ms){0,1}quic' | awk '{print " --redefine-sym " $$NF "=" $$NF "_YB80VJ"}'))
	@objcopy $(renameSymbols) ./dep/msquic/$(TARGET)/bin/Release/libmsquic.a
