Issues trying to build source code

[Todd Defilippi]

I have some issues trying to build the gRPC source code from the tgz-ball.  Is this the right place to ask about that?

Thanks,
Todd

Actually I think I may have figured it out.  I was getting some pkg_config complaints about libcares (which I had already installed on my system).  Running as

make HAS_PKG_CONFIG=false HAS_SYSTEM_CARES=true

seems to have solved that problem and it's building for now.  Fingers cross it continues to!

Thanks,
Todd

I now I am getting a build error:

I have a 1.10 cares RPM installed, it sounds from other comments that 1.10 will not work; is that correct?  Do I need a 1.11 libcares?

Thanks,
Todd

Yes, the minimum libcares version supported is 1.11.0 .

[Todd Defilippi]

Thanks!  I was able to get everything built and RPMed with libcares 1.11.
