after adding my custom plugin I am getting this error.

"C:\Development\wsbuild64\Wireshark.sln" (default target) (1) ->        "C:\Development\wsbuild64\plugins\epan\homematic\homematic.vcxproj.metaproj" (default target) (27) ->        "C:\Development\wsbuild64\plugins\epan\homematic\homematic.vcxproj" (default target) (124) ->        (CustomBuild target) ->          C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Microsoft\VC\v160\Microsoft.CppCommon.targets(209,5): error MSB6006: "cmd.exe        " exited with code 1. [C:\Development\wsbuild64\plugins\epan\homematic\homematic.vcxproj]

I looked in visual studio output window and its showing this error :

CMake Error at cmake_install.cmake:37 (file):
file cannot create directory: C:/Program Files

But I installed cmake before. And before adding my custom plugin I was not getting any such error and it was building perfectly.

Please redirect the msbuild ouput to a file (append 2>&1 > file.txt to the command), post the file on a file sharing site, e.g. Google Drive, DropBox etc. and then post a link to the shared file back here.

You should also note that VS2019 isn't yet used for any official builds of Wireshark, so you're running on the "bleeding edge" here.

I have attached my error as well as my plugin in this location. Kindly help.

You appear to have an odd and unsupported build environment. From the first line in the error log:

Setting environment for using Microsoft Visual Studio 2010 x64 tools.

VS 2010 isn't supported for current master, you must use VS 2015 or later, ideally VS 2017 as it's currently used for Wireshark releases.

Then the subsequent output implies that you have asked CMake to generate a build file for VS 2019 (16.0):

Project file contains ToolsVersion="16.0". This toolset may be unknown or missing, in which case you may be able to resolve this by installing the appropriate version of MSBuild, or the build may have been forced to a particular ToolsVersion for policy reasons. Treating the project as if it had ToolsVersion="4.0". For more information, please see
    70>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Platforms\x64\Microsoft.Cpp.x64.Targets(507,5): error MSB8008:
        Specified platform toolset (v142) is not installed or invalid. Please make sure that a supported PlatformToolset value is selected. [C:\Development\wsbuild64\ZERO_CHECK.vcxproj]

In summary:

  1. Install VS 2017.
  2. Delete your build directory (wsbuild64) and recreate it again.
  3. Open a VS 2017 command prompt for x64 compilation.
  4. Set the required env vars.
  5. Run the CMake generation step specifying VS 2017 and x64 as the generation target.
  6. Run msbuild.

i.e. do exactly as it says in the Developers Guide. If you stray from the guide, you're likely to end up with issues as you've discovered.

From the middle of the output (tip, search for "error"):

Please tell me how do I identify and handle an illegal non-UTF-8 character? I can add my custom plugin if you say so. Kindly help.

since my code is written in c I am not able to find a way to remove or handle it

Open your editor and look at the character at offset 31742 in the file.
