Compiling Live555 chokes on OpenSSL

[NeverOddOrEven]

I am building on Linux Mint 19.3 (Ubuntu 18.04) with Python 3.8.2 in a virtual environment.

:ok_man: side note I did see the warnings about the numpy version being consistent across valkka-core and valkka-live. I figure since I am building from source and using the same venv for both, I should be fine. Famous last words!

Steps to reproduce

git clone https://github.com/elsampsa/valkka-core
cd valkka-core
./prepare-build.bash
./easy-build.bash

Diagnostic error

I was able to get around this by copying the the config.linux-no-openssl packaged with the Live555 tarball over the existing ext/config.linux-generic. I also added the -fPIC flag to the COMPILE_OPTS after getting the subsequent build error :).

:ok_man: side note In case anyone else tries to compile this from within a virtual environment, make sure you revert the hard-coded path to your Python environment in the CMakeLists.txt file. It won't stop a successful compile, but it probably will prevent you from using it with Valkka Live.

Submit a PR?

I am happy to submit a PR with fixes but before I do, I'm curious to know if anyone else gets this same issue with OpenSSL?

I am had the same issue with you

[elsampsa]

Weird.. never had this issue myself & unable to reproduce it in my Ubuntu 18.04 box.

I don't think that the solution is to compile without openssl. Could it be that you don't have openssl installed?

What does this say?

sudo dpkg -L openssl

You might also need to install the openssl development packages with:

sudo apt-get install libssl-dev

If that doesn't solve the issue, after running easy-build.bash etc, please go to ext/llive folder and do this:

cat Makefile > makefile.txt

and

make VERBOSE=1 > makefile_output.txt

Drag'n drop the text files into this ticket & we'll investigate further.

But as I said, I think it's just some missing package in your system.

Finally stumbled upon this myself. "Refreshing" live555 to the latest version reproduced this for me. It's now fixed it the lastest commit & "easy_build.bash" should work again.

..ah and remember to run "configure_live.bash" again before using easy_build
