Debian9 -lsleepy_discord linking issues #56

Open noglass opened 6 years ago

noglass commented 6 years ago

After installing all needed libraries and packages and successfully compiling sleepy_discord, when compiling the hello example, I get linking errors with libsleepy_discord:

I am on Debian 9.4.0 with g++ (Debian 6.3.0-18+deb9u1) 6.3.0 20170516

You may also want to add -pthread to the tutorial as it is needed on linux.

Further notes, just incase, I also tried to compile sleepy_discord with -pthread, but I don't believe it is necessary as it compiles either way. Same end result with and without it.

Also, I ran the setup.py with options 1 and 0 1, everything was successful.

Initially, when trying to compile, I ran into the issue with openssl where SSL_R_SHORT_READ is undefined, I fixed this by applying this patch: https://github.com/LocutusOfBorg/websocketpp/commit/1dd07113f2a7489444a8990a95be42e035f8e9df

After applying the patch and successfully making, the file ./buildtools/libsleepy_discord.a exists and is seemingly found by the linker.

Upon further investigation, I found this:

nigel@dontdeleteme:~/Documents/SleepyDiscord/sleepy-discord/examples/hello$ g++ -std=c++11 -I ../../include -I ../../include/sleepy_discord -I ../../deps -I ../../deps/include -I ../../include/sleepy_discord/IncludeNonexistant -L../../buildtools -L/usr/lib -pthread -lcurl -lssl -lcrypto example0.cpp ../../sleepy_discord/*.cpp ../../sleepy_discord/*.c -o example.out
../../sleepy_discord/websocketpp_websocket.cpp: In member function ‘virtual SleepyDiscord::Timer SleepyDiscord::WebsocketppDiscordClient::schedule(std::function<void()>, time_t)’:

   return [timer]() { timer->cancel(); };
                                       ^

Note: Because I did not install uwebsockets, I renamed ./sleepy_discord/uwebsockets_websocket.cpp so that g++ would not include it.

However, when running make -f Makefile.linux; ./buildtools/websocketpp_websocket.o is created..

yourWaifu commented 6 years ago

I'm not at home, where my computer is, so I can't confirm that this works but I think changing

return [timer]() { timer->cancel(); };

to

return Timer([timer]() { timer->cancel(); });

may fix the could not convert lambda. The others, I'll need wait til I'm at my computer to do some testing.

Thanks for the fast reply!

With that change, I was able to compile the example with the following command:

nigel@dontdeleteme:~/Documents/SleepyDiscord/sleepy-discord/examples/hello$ g++ -std=c++11 -I ../../include -I ../../include/sleepy_discord -I ../../deps -I ../../deps/include -I ../../include/sleepy_discord/IncludeNonexistant -L../../buildtools -L/usr/lib -pthread -lcurl -lssl -lcrypto ../../deps/cpr/cpr/*.cpp ../../sleepy_discord/*.cpp ../../sleepy_discord/*.c example0.cpp -o example.out
nigel@dontdeleteme:~/Documents/SleepyDiscord/sleepy-discord/examples/hello$

It also appears that CPR may not be properly installed in the setup.

Without manually compiling each file every time, I still get various linking errors. I even tried adding the compiled .o files instead of recompiling each one, but to no avail:

This is with a newly compiled setup after making the Timer change.
