I guess live555 have been updated and does not compile anymore Please check https://github.com/mpromonet/v4l2rtspserver that have been updated for that

This does compile.

However it looks like the live555 that the above repo uses does not cross-compile (link fails with strlcpy/strlcat refs).

[nik0]

Try removing the live555 folder And recompile only this one

[claud9999]

Unclear what I should do...

% cd Main/Modules/live
% rm -rf live555
% ./compile.sh

results in...

(Same problem as with the version in mpromonet's repo.)

[nik0]

It seems that the problem is from the lib crypto Try rm _install/libssl.a and libcrypto.so and folder 01libressl/libressl and try recompile with 01 libressl/compile.sh

I'm confused and, instead of going back-and-forth on this ticket, I'm on Discord claud9999#0869 if you'd like me to screen-share.

[claud9999]

Been looking around to see if I can get an (official) older release of live555 to see if I can build things, I'm thinking maybe the "working" release of live555 should be added to this github repo rather than pulling from live555.com?

[nik0]

You maybe right Check in compile.sh of live there are some links to get older version Check also the long conversation here: https://github.com/Dafang-Hacks/Main/issues/47

Sorry I don’t have a lot of time for this project now ...

[claud9999]

I've tried both the git source and Gentoo source and neither works. :| Will keep trying!

[claud9999]

Slowly "porting" this to the latest live555 codebase; now running into a compiler error unable to link libalog--which is in the submodule Main/Audio but doesn't seem to get built by compile_modules.sh? The Makefile in Main/Audio doesn't work, referencing a toolchain folder that don't exist. @nik0 can you take a look at Main/Audio and ensure it's current?

[claud9999]

For that matter, seems there's a circular dependency--I can't build v4lrtspserver-master 'cause it's looking for libalog but I can't build libalog 'cause the Audio/AudioPlay makefile is looking for v4lrtspserver-master/uclibc/... files.

[nik0]

In the closed issue I mentioned earlier the guy successfully compiled with this command lines: git clone --depth=1 --recurse-submodules https://github.com/Dafang-Hacks/Main.git Hacks-Main-TEMP cd Hacks-Main-TEMP ./compile_modules.sh > compile_modules.log 2>&1 cp ../firmware_mod/lib/libalog.so _install/lib/libalog.so cp ../firmware_mod/lib/libimp.so _install/lib/ cp ../firmware_mod/lib/libsysutils.so _install/lib/ cd v4l2rtspserver-master ./compile.sh > compile.log 2>&1

[claud9999]

Ok sounds like he's grabbing the libs from the binary release. I'll do that for now, but this should be fixed in the source too. :o (Want me to file a new ticket?)
