Qt Creator 4.7.2 update problems

MartinD

Hi,
using maintenance tool, I upgraded Qt Creator from 4.0.1 (I'm not 100 % sure) to 4.7.2. Now, I have two problems:

My autoconfigured kit Desktop Qt 5.7.0 MSVC2013 32bit is not properly configured. due to error: Compilers produce code for different ABIs x86-windows-msvc2013-pe-32bit, x86-windows-msvc2015-pe-32bit. For this kit, the C compiler auto selected is Microsoft Visual C++ Compier 14.0 (x86), C++ compiler is Microsoft Visual C++ Compier 12.0 (x86). Before Qt Creator upgrade, the kit was configured properly.
When I run my app (CTRL + R), I get error:

22:54:32: Starting D:\MyProject\debug\MyProject...
22:54:32: Failed to start program. Path or permissions wrong?
22:54:32: D:/MyProject/debug/MyProjectexited with code -1
22:54:32: The process failed to start. Either the invoked program "D:/MyProject/debug/MyProject" is missing, or you may have insufficient permissions to invoke the program.

I guess the problem is missing ".exe" in the path (MyProject.exe exists). I don't want to delete pro.user file as my project has quite complex configuration.

Before Qt Creator upgrade, I had no problem launching apps.

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

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.

@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.

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.

@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.

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.
