[SOLVED] Windows 7 deployement problem

cho7kipu

Hi all,

I'm trying to run a programm I wrote using Qt5 beta 2, and while everything runs fine on my computer, I'm unable to start the program from another computer :(

for now, I tried to identify all the DLL that my program requires. Here is the list :

D3DCOMPILER_43.DLL
ICUDT49.DLL
ICUIN49.DLL
ICUUC49.DLL
LIBEGL.DLL
LIBGLESV2.DLL
QTCORE5.DLL
QTGUI5.DLL
QTMULTIMEDIA5.DLL
QTMULTIMEDIAWIDGETS5.DLL
QTNETWORK5.DLL
QTOPENGL5.DLL
QTPRINTSUPPORT5.DLL
QTQML5.DLL
QTQUICK5.DLL
QTSQL5.DLL
QTV85.DLL
QTWEBKITWIDGETS5.DLL
QTWIDGETS5.DLL

But, while I'm able to start my program with these libs from my computer without having qt libs on my PATH (C:\Qt5.0.0beta2\5.0.0-beta2\msvc2010\bin), the program still doesn't start on another computer.

I tried to but the whole bin directory content on the other computer, the result is always the same, although Dependency walker says that everything seems ok (no dll is missing)

When I double-click on the .exe file, simply nothing happens !

So I don't understand what I am missing here :(

Please help me before I hang myself !!

Thank you

PS : using windows 7 64bits and compiling in 32bits using msvc2010

Some additional information...

I just discover the Profiling feature of Dependency Walker, and found that my program doesn't find a valid plugin platform (??!!), see the output below :

Copy the plugin together with libraries (IIRC, it should reside in <exe root>/plugins/platform, but my memory is not good in that respect).

cho7kipu

my program doesn't have any plugin (and so there isn't any plugins directory within my exe output root directory :-/ )

sierdzio

It is Qt platform plugin for Windows, needed by all Qt5 apps. I'm on Linux, for me the path to find this beast is: <Qt dir>/qtbase/plugins/platforms/libxcb.so. For you it will probably be windows.dll or so.

cho7kipu

Oh, it seems that my program is almost working now. After copying windows.dll I was still having some problem (no icon in my toolbar for example) so I copied some other plugins (iconengines, imageformats, etc) and now the program is running but only if I launch it via Dependecy Walker Profiles menu

Very weird

sierdzio

Wow. Now this has got really strange :)

cho7kipu

OK. I succeed to start the application without Depency Walker... I had to create a qt.conf file then :

bq. [Paths]
Plugins = plugins

I don't know why, though....

Thank you so much for your help sierdzio !

sierdzio

Pleasure, happy coding. Please mark the thread as [Solved] if you consider the matter to be clear.

I've used the Windows Event Viewer before to identify missing dependencies. (Control Panel-> System and Security -> Administrative Tools ->Event Viewer)
When you run an executable and a dependency is missing frequently you'll get an event log specifying exactly what you are missing.

I've used this before when building installers for DirectX projects, though I don't know if this would work for Qt.
