Qt Creator 4.7.2 update problems

[jsulm]

@MartinD said in Qt Creator 4.7.2 update problems:

C compiler auto selected is Microsoft Visual C++ Compier 14.0 (x86), C++ compiler is Microsoft Visual C++ Compier 12.0 (x86)

Select the proper compiler for both (12.0 I guess).

@MartinD said in Qt Creator 4.7.2 update problems:

I don't want to delete pro.user file as my project has quite complex configuration.

Unfortunately, sometimes that's the only way to fix things.

But how about copying your project into a second folder, delete the .pro.user there and doing a clean rebuild?

[MartinD]

I configured my Qt 5.7.0 manually and selected correct compilers.

I deleted old pro.user file and manually reconfigured my project again.

EDIT: Nope, still this error:

16:55:48: Starting D:\MyProject\debug\MyApp...
16:55:48: Failed to start program. Path or permissions wrong?
16:55:48: D:/MyProject/debug/MyAppexited with code -1
16:55:48: The process failed to start. Either the invoked program "D:/MyProject/debug/MyApp" is missing, or you may have insufficient permissions to invoke the program.

D:/MyProject/debug/MyApp.exe exists. MyProject is subdirs project. I can run other subprojects of my project from QtCreator, but this particular one I can't. MyApp links to some dlls (but also other projects from my subdirs project do), maybe this is the issue.

Still, I can't see .exe in the path D:/MyProject/debug/MyApp .

Any advise?

[MartinD]

I disabled protection in My Kaspersky antivirus which I use - didn't help.

[jsulm]

@MartinD After reconfiguring did you rebuild your app (delete the whole build directory)?
Did you try to start the app manually?

[MartinD]

Yes, I deleted the build directory, the project was rebuilt.

Manually, the app runs (when ll neccessary dlls are manually copied to the folder).

[jsulm]

@MartinD You should check the "Run Settings" of your project

[MartinD]

Run settings are default. Executable is "D:\Projects\build-MyProject-Qt_5_7_0_MSVC2013_32bit-Debug\MyApp\debug\MyApp" and Working dir is "D:\Projects\build-MyProject-Qt_5_7_0_MSVC2013_32bit-Debug\MyApp". Run in terminal unhecked, Add build library search path to PATH checked.

All three executable subprojects in my subdirs project have this configuration. Two subprojects can run, this one can't.

I haven't changed anything in run confiuration after Qt Creato upgrade.

[jsulm]

@MartinD Executable and working directory can't be same!
If "D:/MyProject/debug/MyApp.exe" is executable then working dir should be "D:/MyProject/debug".

[MartinD]

It is not the same:
Executable is "D:\Projects\build-MyProject-Qt_5_7_0_MSVC2013_32bit-Debug\MyApp\debug\MyApp"
Working dir is "D:\Projects\build-MyProject-Qt_5_7_0_MSVC2013_32bit-Debug\MyApp"

I also tried to minimize my problematic executable project by compiling only empty main function. The executable now links only to some system dlls. Still the same issue.

[MartinD]

My colleague copied me old version of Qt Creator he has installed (4.0.3). This version can launch the project. There is obviously some issue in new Qt Creator.

[aha_1980]

Hi @MartinD,

All three executable subprojects in my subdirs project have this configuration. Two subprojects can run, this one can't

I guess the problem is missing ".exe" in the path (MyProject.exe exists).

Combining these two statements, do the other two subprojects (that can be launced) have the .exe suffix?

[MartinD]

No, they also don't have .exe suffix in new Qt Creator.

In old Qt Creator application output when launching starts with:

Starting D:\Projects\build-MyProject-Desktop_Qt_5_7_0_MSVC2013_32bit-Debug\MyApp\debug\MyApp.exe...

Whereas in new Qt Creator, as I have already written, there is no .exe suffix. Is this the issue? However, I still don't understand how it is possible that two projects can run and one not.

[aha_1980]

@MartinD said in Qt Creator 4.7.2 update problems:

However, I still don't understand how it is possible that two projects can run and one not.

It could still be that the program crashes because it cannot load a dependent library. Have you checked if you can start the app outside Creator?

[MartinD]

Yes, the app can run outside Qt Creator. Also, Qt Creator 4.0.3 can launch this app. Only new Qt Creator 4.7.2 can't launch it.

[aha_1980]

@MartinD Please check the Run Environment (Project > Build & Run > Run > Run Settings > Run Environment - especially PATH. I'm pretty sure it's related to something there.

[jsulm]

@MartinD said in Qt Creator 4.7.2 update problems:

Executable is "D:\Projects\build-MyProject-Qt_5_7_0_MSVC2013_32bit-Debug\MyApp\debug\MyApp"
Working dir is "D:\Projects\build-MyProject-Qt_5_7_0_MSVC2013_32bit-Debug\MyApp"

Try to change the working directory to "D:\Projects\build-MyProject-Qt_5_7_0_MSVC2013_32bit-Debug\MyApp\debug"

And compare these settings with QtCreator 4.0.3

[MartinD]

Already tried setting working directory to that.

The difference is, that in Qt Creator 4.0.3 the Executable has .exe suffix, there is D:\Projects\build-MyProject-Qt_5_7_0_MSVC2013_32bit-Debug\MyApp\debug\MyApp.exe

[jsulm]

@MartinD Well, in my QtCreator there is no .exe suffix as well and the app starts from QtCreator. Must be something else. As @aha_1980 said it is most probably something in Run settings - you can compare those too between both QtCreator versions.

[MartinD]

@aha_1980 Thanks for that point. I found that old Qt Creator adds multiple x64 paths to PATH (my app is 32 bit), e.g.:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\Team Tools\Performance Tools\x64
C:\Program Files (x86)\Windows Kits\8.1\bin\x64
C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools\x64\

Whereas new Qt Creator has:
C:\Program Files (x86)\Microsoft Visual Studio 12.0\Team Tools\Performance Tools
C:\Program Files (x86)\Windows Kits\8.1\bin\x86
C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools\

Otherwise, the PATH is same. Changing the PATH in new Qt Creator to what old Qt Creator uses has no effect.
