for building and executing on windows it can be a little bit tricky, so I'll post my solution for anyone that wants to run it on windows

step 1: building the tdlib

first, install visual studio and build the binaries using this instruction

build instruction

if you had any problem in building the tdlib library it can be for one of the below reasons

• wrong visual studio components were installed
• you need a proxy for downloading the dependencies (especially for Iranians)

then copy the directory ( the whole tdlib directory ) into the same drive that you want to execute your app, dont need to be in the exact directory just on the same drive

step 2: Installing GCC

install msys64 for MinGW and GCC

set a new path environment to point to MinGW and its bins
note replace it with your bin folder ( default is this )
C:\msys64\mingw64\bin

step 3: set needed environment variables

set this environment variables

CGO_CFLAGS
-IC:\td\tdlib\include

CGO_LDFLAGS
-LC:\td\tdlib\bin -ltdjson

replace C:\td with your td installation path

then set td path built bins to your environment paths

C:\td\tdlib\bin

again replace the path with your build directory

after that, you can execute your app and use the go-tdlib library
