Hi all

I am using following versions:

Wireshark Version - 2.6.5
QT Version - 5.6
MSVisual Studio - 15

I am able to build and package Wireshark using following commands: Make:

msbuild /p:Configuration=RelWithDebInfo <>\Wireshark.sln
msbuild /p:Configuration=RelWithDebInfo <>\Wireshark.sln /t:Clean

Packaging:

msbuild /p:Configuration=RelWithDebInfo nsis_package_prep.vcxproj
msbuild /p:Configuration=RelWithDebInfo nsis_package.vcxproj

Wireshark exe is generated successfully, but when i tried to execute it is giving following error as pop-up.

"This application failed to start because it could not find or load the Qt platform plugin "Windows" in "".

When i execute Wireshark.exe just after the build it works fine. I tried to find out that it is because QT DLLs are not included properly.

Request your help to understand what changes to be done in configuration to include QT DLLs.

Thanks Kiran Kumar G

The cmake build process for Wireshark uses the Qt application windeployqt to copy the required Qt DLL's into the run\RelWithDebInfo directory, and the nsis packaging step copies those into the installer.

If you can execute Wireshark from the run\RelWithDebInfo directory then the relevant Qt DLL's have been copied.

If, after running the installer, an installed version of Wireshark fails, then it's likely that the installer did not pick up all the required DLL's.

What Qt*.dll files do you have in the run\RelWithDebInfo directory and what do you have in the installed Wireshark directory?

Inside run\RelWithDebInfo there are:

Qt5Core.dll
Qt5Gui.dll
Qt5Multimedia.dll
Qt5Network.dll
Qt5PrintSupport.dll
Qt5Svg.dll
Qt5Widgets.dll
Qt5WinExtras.dll

But, inside installed Wireshark directory there is none. Is something missing ?

Thanks

OK the expected 8 files, can you share the output from the msbuild … nsis_package.vcxproj step? Add 2>&1 > package.txt to redirect the output to a file, then post the package.txt file to a public file share, e.g. Google Drive, DropBox etc. and then post a link to the file back here.

Hi Graham I have uploaded the package.txt file at the following location, request your inputs. https://drive.google.com/folderview?i...

Let me know if any issue in accessing the folder. Thanks.

Hi Graham, any inputs on the build logs ?

The size reported by nsis is curiously small, e.g. from your build:

  EXE header size:              328192 / 36864 bytes
  Install code:                          (145459 bytes)
  Install data:                          (111442756 bytes)
  Compressed data:            33852951 / 111588215 bytes
  CRC (0x28408604):                  4 / 4 bytes

And from the 2.6 x86 buildbot:

  EXE header size:              328192 / 36864 bytes
  Install code:                          (155017 bytes)
  Install data:                          (172369951 bytes)
  Compressed data:            53799604 / 172524968 bytes
  CRC (0x55569A31):                  4 / 4 bytes

Your "Install data" is approx 60 MB smaller.

I'm really not sure what's going wrong here.
