Api: link error

[rvalvekar]

error: undefined reference to `TgBot::Api::Api(std::__cxx11::basic_string<char, std::char_traits, std::allocator > const&)'

I have been linking libraries as per given on github. The Samples work just fine, when i try to implement in other programs, the program gives error.

Plus the library has a lot of issues with boost and gateway time outs.

@rvalvekar do you have any of the described above problem with the latest TgBot from master?

@rvalvekar Yes, I do:

oddly enough including #include <spdlog/spdlog.h> does fix this, but since I have other options I would like to get rid of this lib.

Hey guys, I had similar issues and I fiddled a lot, but this seemed to help:

$ conan profile update settings.compiler.libcxx=libstdc++11 default

Dont know to what is was set before, maybe just libstdc++ but this made the change for me. You might want to do a

$ conan install --update .

afterwards :man_shrugging:

This gave me the hint: https://github.com/reo7sp/tgbot-cpp/issues/14#issuecomment-872338093
