| Mastah | Hi, I am facing some trouble with latest protobuf 3.1 and trying to compile Mir's protobuf bindings; | 11:39 |
|---|---|---|
| Mastah | In 3.1 the following change was applied: Moved default_instances to global variables. This allows default_instance addresses to be known at compile time. | 11:40 |
| Mastah | and when now trying to compile Mir against 3.1, I get this error: | 11:40 |
| Mastah | ./obj-i686-linux-gnu/src/client/./src/client/mir_debug_api.cpp:32: undefined reference to `mir::protobuf::SurfaceId_default_instance_' | 11:40 |
| Mastah | I am not acquinted with either protobuf, and Mir's code, to be honest, so I could use some guidance how to work around this issue and a adapt to new the changed _default_instance_ behaviour | 11:40 |
| anpok_ | Mastah: ok .. sounds like you might then have to adjust the symbols.map of mirprotobuf.. so that the client debug api can access it.. | 13:01 |
| anpok_ | that would be in src/protovbuf/symbols.map.. | 13:02 |
| Mastah | ok, I had already tried just removing them, but that didn't work ;) | 13:12 |
| Mastah | in what manner do you think they ought to be changed? | 13:13 |
| anpok_ | i dont know exactly what those globals are user for... but the debug api related code lives outside of mirprotobuf so that symbol would have to be exported | 13:21 |
| anpok_ | basically you would have to add another line in the symbols.map mentioning that mir::protobuf::SurfaceId_default_instance*; | 13:22 |
| Mastah | ok, thank you. I will try to experiment with such lines :) | 13:29 |
| Mastah | @anpok, unfortunately that didn't work; I tried with both mir::protobuf::SurfaceId_default_instance*; as mir::protobuf::SurfaceId_default_instance_*; in the symbol.map, but the same error remains :/ | 14:00 |
| Mastah | @anpok, the build errors can be seen here: https://launchpadlibrarian.net/288864417/buildlog_ubuntu-yakkety-i386.mir_0.24.0+16.10.20160815.3-0ubuntu3+maarten2_BUILDING.txt.gz | 14:00 |
| Mastah | @anpok, I gotta go in a moment, I made an issue for it: https://bugs.launchpad.net/mir/+bug/1631597 | 14:38 |
