Linux Project Linking Errors

[TylerTheFox]

I did a fresh clone from master and now I can't figure out how to link again. Tried with the original make file and that didn't produce any better results.

Also suggestion: Add the examples to the TravisCl automated build to test linking.

This is the code that requires linking to sleepy discord. https://github.com/Brandantl/Monero-TipBot/blob/develop/src/Discord.h https://github.com/Brandantl/Monero-TipBot/blob/develop/src/Discord.cpp

Here is my build commands.

g++ -Wall -c -std=c++11 -fPIC ../sleepy_discord/.cpp ../sleepy_discord/.c ../deps/cpr/cpr/.cpp -I ../include/sleepy_discord -I ../deps/include -I ../include/sleepy_discord/IncludeNonexistent ar rv libsleepy_discord.a .o mv libsleepy_discord.a ~/Monero-TipBot/extern/sleepy-discord/lib/linux/libsleepy_discord.a

Output of the ar command

[yourWaifu]

It looks like you don't have websocketpp in your includes or deps and that you didn't link cpr. To fix this, I think you need to download websocketpp and it's dependencies (the setup script should help with that), include cpr and compile it and link it with -lcpr.

[TylerTheFox]

Thats included in the compile command

g++ -Wall -c -std=c++11 -fPIC ../sleepy_discord/.cpp ../sleepy_discord/.c *../deps/cpr/cpr/.cpp** -I ../include/sleepy_discord -I ../deps/include -I ../include/sleepy_discord/IncludeNonexistent

you can even see the CPR .o files in the ar command auth.o error.o cookies.o etc.

[TylerTheFox]

Turns out I didn't copy the new headers. Heres the compiler error I get now with the headers copied. Has anything changed with those functions?

Example of the errors is because of this vector() call https://github.com/Brandantl/Monero-TipBot/blob/develop/src/Discord.cpp#L220

I found it really strange that operator const std::string&() isn't working in your case. I'm going to guess that a static_cast<std::string>() might fix most of the issues.

[TylerTheFox]

It's only the new version of sleepy discord. I just compiled the old version without issues. And only on Linux. Windows is OK for some reason.

static cast or wrapping it in std::string does not work.

[TylerTheFox]

I reverted to this version of snowflake.h and it compiled w/o issues https://github.com/Brandantl/Monero-TipBot/blob/develop/extern/sleepy-discord/include/sleepy_discord/snowflake.h

[TylerTheFox]

This was because of conflicts with master.
