Hi,

How do you link this library? Are you using cmake to generate VS project?

---

Build tgbot library statically, it should help. InputFile is not exported indeed.

[egorpugin]

I've added missing TGBOT_API. But this might not help you until you try static build. https://github.com/reo7sp/tgbot-cpp/commit/a79166516734d965032b5e94b66f1aae9f493424

when I try to compile it gives an error such $ cmake . -- Building for: Visual Studio 16 2019 -- The C compiler identification is MSVC 19.24.28314.0 -- The CXX compiler identification is MSVC 19.24.28314.0 -- Check for working C compiler: C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.24.28314/bin/Hostx64/x64/cl.exe -- Check for working C compiler: C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.24.28314/bin/Hostx64/x64/cl.exe -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.24.28314/bin/Hostx64/x64/cl.exe -- Check for working CXX compiler: C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.24.28314/bin/Hostx64/x64/cl.exe -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Looking for pthread.h -- Looking for pthread.h - not found -- Found Threads: TRUE CMake Error at D:/cmake-3.16.2-win64-x64/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message): Could NOT find ZLIB (missing: ZLIB_LIBRARY) (found version "1.2.11") Call Stack (most recent call first): D:/cmake-3.16.2-win64-x64/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:393 (_FPHSA_FAILURE_MESSAGE) D:/cmake-3.16.2-win64-x64/share/cmake-3.16/Modules/FindZLIB.cmake:115 (FIND_PACKAGE_HANDLE_STANDARD_ARGS) CMakeLists.txt:40 (find_package)

@ummdd you should provide all required dependencies to your application. You can do it manually (but it's not recommended way).

I suggest you to use Conan dependency manager (https://docs.conan.io/en/latest/). Then try to use tgbot-cpp library from Conan (e.g. you can use my package: tgbot-cpp/1.1@zamazan4ik/testing).

I hope it will help you.

@ummdd I have the same problem. Under ubuntu you can fiz this by installing libz sudo apt-get install zlib1g-dev

After that I also had to install libcurl sudo apt-get install libcurl14-openssl-dev

That fixed for me

I suggest you to use Conan dependency manager (https://docs.conan.io/en/latest/). Then try to use tgbot-cpp library from Conan (e.g. you can use my package: tgbot-cpp/1.1@zamazan4ik/testing).

Your package doesn't seem to exist. Is there anything i'm missing here? I'm using the command conan install tgbot-cpp/1.1@zamazan4ik/testing

[zamazan4ik]

@CyrusDe I think you just forgot about adding my remote for using this package. My conan package for tgbot-cpp is available here: https://bintray.com/zamazan4ik/conan/tgbot-cpp%3Azamazan4ik

Before conan install tgbot-cpp/1.1@zamazan4ik/testing you need add my remote with the following command: conan remote add zamazan4ik https://api.bintray.com/conan/zamazan4ik/conan

Hope it'll help you.

@ZaMaZaN4iK Tried the commands and it installed the dependencies but the tgbot files seem to have problems. Conan produces this log:

Also trying to build it just using Cmake throws this error: "Error in configuration process, project files may be invalid.

[zamazan4ik]

I don't know why but CMake tries to use pthread.h on Windows. Didn't meet such problems before (since I don't use Windows).

[egorpugin]

@CyrusDe You could try my fork https://github.com/egorpugin/tgbot with other package manager (SW).
