Compiling error

[aitherios]

When compiling I got:

make steam

I did compile this project before but I just updated SteamKit. Could you shed some light? I can spend some time trying to fix it (and pull requesting), I just wanted to understand if I'm doing something stupid (probably)

[seishun]

Yeah some protobufs got moved around. It should be a trivial fix.

[Python1320]

I have it fixed at https://github.com/Python1320/SteamPP

More specifically: Python1320@cc38bac#diff-78ccbafc6289159f37af56b7eafb0c47R6 and Python1320@80e1cc2#diff-af3b638bc2a3e6c650974192a53c7291R13

[aitherios]

Yes, I compiled without a problem =D. This would be a nice pull request Python1320.

[Alessandro-Barbieri]

I got the same error of aitherios.

[Xylemon]

Will this ever be worked on again? A Pidgin plugin that doesn't use the mobile protocol for Steam sounds nicer than the other abandoned plugin.

[SeriousMatters]

Tried to compile https://github.com/Python1320/SteamPP and got the following error.
Roll back 1 commit (Python1320@3393b89) then it compiles fine. No noticeable problem using it either.

I can't get it to compile at all, just keeps telling me:

[AshleighAdams]

@Xylemon, You need to clone SteamKit, set the STEAMKIT variable to where you cloned it in cmake-gui, click "Configure", then click "Generate"; make should now compile it:

@SeriousMatters, I get same my end too..

[VictorGladys]

This problem may be playing again, SteamKit moved some protofiles around again.

It was fixed for me by adding
#include "steammessages_clientserver_2.pb.h"
#include "steammessages_clientserver_friends.pb.h"
#include "steammessages_clientserver_login.pb.h"
to the includes in cmclient.h

and editing CMakeLists.txt to also include the corresponding libraries when compiling
