Crash when run in Release mode?

mzimmers

target.path = $$OUT_PWD
target.files = "LimeReport.dll" "QtZint.dll"
INSTALLS += target

This link OUT_PWD will explain how it works.

Just make sure to add the install step to your build. Adding this stuff to the .pro files is just specifying what the install will work on.

I can't answer why it worked in 5.13.

Hi @mzimmers,
I copied above lines in my pro file and add make step to build like below picture. But still same crash?!
I affraid I could not copy dll's to destination folder. :(
Where am I wrong?...

The first thing I'd check is, did the files copy over to the release directory?

I was making an assumption that you had those files available in your source directory; if not, then you need to furnish the pathnames in the .pro file.

@mzimmers ,
No. Files did not copied in the folder. But when I add below string than everything solved. I can run program in release mode too.

target.path = $$OUT_PWD
target.files = "D:/Belgeler/Qt/LimeReport/win64/release/lib/LimeReport.dll" "D:/Belgeler/Qt/LimeReport/win64/release/lib/QtZint.dll"
INSTALLS += target

Thanks...

Excellent. If you like, you can create a variable in your .pro file for your directory that contains the libraries, and use that variable when specifying the target.files. Won't change the behavior; it's just a bit cleaner.

If you think this is resolved, please mark the topic as solves using the topic tools available in your first post in this thread.

@mzimmers
I already marked your post as answer... :)

By the way there is still one question more: What is the difference between 5.13.2 and 5.14.2?... :)

@Mucip That is something that you can find out in the release notes as well as in the git history.

But whatever the differences are, I seriously doubt they have anything to do with the problem you encountered. More likely, when you updated, you also created a new .user file that wiped out your build settings.

Hi @mzimmers ,
In any case, I learned new and very usefull things. Thanks.

Hi @mzimmers ,
Let's suppose there is report folder in the main project directory and some xml files in this report directory. I want to copy report folder and contents to the target directory too. Above information I can copy files to target but what about create folder and copy files to target directory on compile time?

mzimmers

@Mucip yes, you can do that. The details can be found here.

Mucip

@mzimmers ,
I got it thanks.
Maybe someone has same problem. I solved like below.
The code create "rapor" folder and copies contents to target build directory.

target.path = $$OUT_PWD/release
target.files = "D:/Belgeler/Qt/LimeReport/win64/release/lib/LimeReport.dll" "D:/Belgeler/Qt/LimeReport/win64/release/lib/QtZint.dll" $$PWD/rapor
INSTALLS += target

Looks good. Thanks for posting the solution.

If some DLL are missing It shouldn't compile the project, should it?

If they are missing at compile time then yes it will not compile.
But in your case they are missing at runtime.
QtCreator prepares the environment before starting your app, so it can find all libraries.
If you want to start your app outside of Qt creator you need to deploy it first: https://doc.qt.io/qt-5/windows-deployment.html

Mucip

@jsulm ,
No. I already use and know WinDeployQt. The problem was here is, I can not run the RELEASE build inner Qt Creator. And when I add above lines to the pro file than I can run the RELEASE build inner Qt Creator too.

If the above tips haven't helped, here's another: I had a bug in a function that should have returned a bool (but returned nothing) that caused the project release version to crash while the debug version ran OK. After adding the missing line of code both versions ran.

Dear @theldl ,
Where is the bug and did you inform LimeReport forum?...
