Re: [Linphone-developers] Error compiling linphone-sdk

[john]

Answering my own question...

I got past this by compiling bctoolbox without strict rules:

./linphone-sdk/build/WORK/desktop/Build/bctoolbox% cmake . -DENABLE_STRIC
T=NO
make

I then continued overall build with the cmake in the build directory.

I am not sure why this is not a general problem.   Maybe it occurs with certain versions of gcc.

Hello,

I previously had linphone-sdk compiled on my Fedora (36) linux computer.   Recently I started up qtcreator and it would not build my linphone-sdk application anymore.   I re-cloned the SDK and configured it with same options I used previously.  However now I get these errors when I go to make it:

Any idea where I should look to address it?  

I did double check the dependencies listed on the linphone-sdk github page and all seems fine.   After the errors I provide the config step.
