Wireshark version : 3.2.7

OS : Windows

Issue : While building Wireshark code it is observed that there are thousands of errors when linking with QT library. I verified the QT installed path, QT5_BASE_DIR path in environment variable, all looks good. But, failing to link. What could be the issue.

(Link target) ->

You should note that version 3.2.7 dropped out of support more than two years ago, you really should try to move to a supported version. See lifecycle for more info on versions.

As to your issue, it looks like your build environment isn't configured correctly and isn't linking with the Qt DLLs. Somewhere in the build output there should be the link command line which will show what the link is using.

Sure Graham will ensure to move it to the latest version soon. I verified the paths provided and set for QT5, all looks fine and accessible. As you mentioned below is the link command after which the errors are observed.

Anything I am missing or should I look into related to linking with QT library properly. Thanks in advance.

Wireshark version >= 4.2 should be compiled using Qt6. See https://www.wireshark.org/docs/wsdg_h...

On Windows I set these variables to compile:

set PLATFORM=X64
set WIRESHARK_QT6_PREFIX_PATH=C:\Qt\6.6.0\msvc2019_64

Says in the question & the answer, the target is 3.2.7

grahamb (2023-12-04 17:00:02 +0000) edit

I am building Wireshark 3.2.7 and have set the below path for QT5.

QT5_BASE_DIR and built using below commands

cmake -G "Visual Studio 16 2019" -A x64 .

msbuild /m /p:Configuration=RelWithDebInfo Wireshark.sln
