getting error wsbuild64/wiretap/ascend.c(1155,1): error C2220 when trying to build wireshark sources

edit

It's likely that we would need to see the complete output of both the CMake generation step and the msbuild step. Redirect the outputs to a file by appending 2>&1 > somefile.txt to the commands and then putting the text files on a public share and posting a link back to them here.

Hi, The files can be found here and here

Thank you, Bella

The actual error is:

112>D:/Bella/Wireshark/dev/wsbuild64/wiretap/ascend.c(1155,1): warning C4244: 'initializing': conversion from '__int64' to 'long', possible loss of data

As to why you're getting that, it's something in your env. The generation of ascend.c also looks a bit odd:

112>CustomBuild:
     D:/Bella/Wireshark/dev/wireshark/wiretap/ascend.y:8.1-12: warning: deprecated directive: '%pure-parser', use '%define api.pure' [-Wdeprecated]
         8 | %pure-parser
           | ^~~~~~~~~~~~
           | %define api.pure

...

112>D:/Bella/Wireshark/dev/wireshark/wiretap/ascend.y : warning : fix-its can be applied.  Rerun with option '--update'. [-Wother]

I'm building my self at the moment to check that.

Build and compile is clean for me. What do you have in the CMakeCache.txt file in the build directory for YACC_EXECUTABLE:FILEPATH? That should point to win_bison.exe.

It is YACC_EXECUTABLE:FILEPATH=C:/ProgramData/chocolatey/bin/win_bison.exe The path is correct
