We are upgrading PB from 3.14 to 30.0, on Alma Linux 9, with g++ 11.5.0. We
are using it in C++ as well as Java code.
protoc, shared libs, and include files all show the right release -- 30.0.
The new installs are in /usr/local/... where the old version is in /usr/
directly
When I try to compile our message library using gnu make, we are getting
errors around use of Templates in C code and conflicting definitions of PB
functions. Does this seem familiar to anyone? Below are detailed examples.
We would appreciate any help at all!
