Same issue here

from cld3.

I had this error when trying to install gcld3 in a Ubuntu 20.04 image with protobuf 3.20.1 managed by conda. I fixed it by downgrading the protbuf version to 3.6.1

On my machine (WSL Ubuntu 22.04), I had no problem installing gcld3 with protobuf 3.12.4. My guess is that this issue is caused by some kind of mismatch of protobuf versions. This answer suggests that something regarding this file changed after version 3.7 of protobuf.

(windows, building with visual studio)

1. you need protobuf of at least 3.20. You can install it with vcpkg
2. locate port_def.inc inside protobuf installation
3. set LIBPATH environment variable to a folder, where google/protobuf/port_def.inc located. (not port_def.inc itself)
4. if you have issue with protobuf.lib... I guess it's a bug. There is no protobuf.lib file, there is libprotobuf.lib file. Copy libprotobuf.lib to protobuf.lib in the same folder.
5. 5. set LIB environment variable to a place, where protobuf.lib is located.
