    Visual Studio 16 2019

  could not find any instance of Visual Studio.

• In build.ps1 changed two places that had Visual Studio 16 2019 to Visual Studio 17 2022
• Deleted cache folder (created in the last run)
• Retried . .\build.ps1; Build-Host -BuildType "Release" -Arch "x64"
• Error

Error

Many times mentioning missing nlohmann/json.hpp.

C:\Users\thiag\Downloads\libzt\ext\ZeroTierOne\osdep\OSUtils.hpp(46,10): error C1083: Cannot open include file: 'nlohmann/json.hpp': No such file or directory [C:\Users\thiag\Downloads\libzt\cache\win-x64-host-release\

Note

@jbatnozic mention how to fix nlohmann/json error in #263.

• Added include_directories(${ZTO_SRC_DIR}/ext/) in CMakeLists.txt
• Retried . .\build.ps1; Build-Host -BuildType "Release" -Arch "x64"
• Script finished

Note

It's copying the wrong .lib in line 20.
Creating static library in windows will generate .lib.
Creating shared library in windows will generate .dll and .lib (not the same as static .lib).

libzt/build.ps1

Lines 20 to 23 in 2f0f25a

Error

When using it through terminal nothing happens.

PS C:\Users\thiag\Downloads\testing_libzt> ./main.exe     
PS C:\Users\thiag\Downloads\testing_libzt>

Code

#include "zerotier/ZeroTierSockets.h"
#include <stdio.h>

int main(void) {
  printf("---Start\n"); // This is never printed
  long long net_id = 0x0cccb752f7bdf645;

  zts_node_start();
}

When double clicking main.exe

Note

• Renamed to zt-shared.dll (lazy way to solve)
• Moved to same folder as main.exe
• Executed code to test
• Success
