I set the build architecture to arm64 in os cmake file but still the same issue. really need help. thank you

[gwaldron]

We saw the same problem on the MacOS CI build. Looks like a protobuf problem. We do not have any OSX systems so we will need to rely on you and other OSX users to track this down.

I have also recently been working on osgearth related projects on arm64 architecture CPU machines. I did compile successfully. But I'm not using Apple's operating system。 Good luck to you, buddy。

Removing protobuf from external libraries while compiling helped a lot. However, there are still few errors left:

I suggest SymInitialize() and SymFromAddr() are WinAPI functions (correct me if I am wrong), but why they doesn't link to library?

[ComradeMashkov]

For those who are interested in the same problem: build protobuf 3.21.10 (at least this version is fine for me), because it containts logger class. Then you have to link with dbghelp (-ldbghelp in CMake GUI libraries for CXX), this library implements SymInitialize() and SymFromAddr() functions.

i removed protobuf and glew from cmake file when i compile the OSGEarth on MacOS (M2 Max chip) and i also modified the maxOS platform cmake file , and some other cmake file and also part of the code (there are compiler errors ) , it passed but due to lack of protobuf can not load openstreetmap. i did compile protobuf from source but still have similar link issue. so i skipped the protobuf. i think its mainly because of protobuf, so i close this issue
