System Cannot Find Path Specified

@JonB I pressed the Win key, typed cmd, and pressed Enter:

Hi, the 2nd attempt was the one I was thinking of (set path= on one line, and vcvarsall.bat on the next line)

Now in that same CMd, (after the 2 lines that ends with .. initialzed for x64) try typing
cl

Does it say Microsoft Visual ... or?

JonB

@surferbrain
If you type the command

cmd

from within your Command Prompt, it will start a new one inside the current one. Output should look like:

Microsoft Windows [Version 6.1.7601]

C:\Users\Jon>cmd
Microsoft Windows [Version 6.1.7601]

C:\Users\Jon>

But are you saying that after that cmd inside the Command Prompt you get your
The system cannot find ...
message as it starts the second shell level?

@hskoglund Hi, typing cl after shows:

Maybe now I should try Qt Creator and see if it still creates those cl errors.

@JonB Yup! Even invoking cmd within cmd produces the error:

@surferbrain
I am only commenting on the The system cannot find .... If it were me I would want to track that down and deal with it. However, whatever it is it may be harmless or not related to your Qt situation.

Yes, try ignoring it for now and proceeding....

hskoglund

You seem to have been bitten by PATH poisoning (i.e. some other program is interfering with MSVC)

To be able to pull the same stunt from Qt Creator you will have to launch Qt Creator from that same CMD that has the neutered path (or find a way to do it inside Qt Creator)

I'm wondering, I found some directories that did not exist in my system environment variables. I deleted or modified them to work. I am wondering now if the System Environment path variable in my stock kit looks correct. I would assume it is:

@JonB Qt Creator still produces the same errors. It does say that perhaps:

but we already knew the environment is probably screwed up in some fashion.

Hmm, the PATH looks kosher, maybe it's time to clean those Visual Studios, try keep only one of them (MSVC2019) and uninstall the others (MSVC2017 etc.) Then start MSVC2019 and update it to version 16.6.4.

@hskoglund Thank you for your help.
I currently only have VS 2019 Community and Qt Creator 4.12.4 installed. They were installed after uninstalling all instances of VS and Qt.
I just updated to 16.6.4 and it still produces the same errors/warnings. Ex:

Does anyone else have any possible solutions, besides reinstalling Windows?

hskoglund

Hi, maybe you can use Qt Creator through my suggestion before (i.e. launch a normal (not a Developer) CMD window) and type these 3 lines:

set path=
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" x64
C:\Qt\Tools\QtCreator\bin\qtcreator.exe

If you can compile nside Qt Creator now, you could put those 3 lines a .bat file...

@surferbrain
You need to look inside that vcvarsall.bat file and see what paths it is trying to find/execute which cannot be found. Isn't the problem in your VS set up rather than Creator?

I am still having this problem in 2022. Did no one work on a fix? I thought those enterprise licenses were supposed to pay for something

What "enterprise licenses"? Do you mean some kind of Qt commercial licence? If so why not ask TQtC?

The Qt enterprise license can't fix your Visual Studio installation for you.

If you'd like assistance, please provide diagnoatic information like what @surferbrain did above.

so, can anyone give a step by step guide? I feel like it's taking different path even after specifying it. i=I used ifstream, fstream, ofstream, and QFile, but none worked. It's hard to believe that this issue is not being fixed. I am using QT creator.

JonB

@Nahian
Hello and welcome.

" step by step guide" to what? This thread is a question about the MS-supplied vcvars...bat file having an error in it when run on the user's system, likely nothing to do with Qt.

I used ifstream, fstream, ofstream, and QFile, but none worked.

Used them for what? I don't see any connection between these calls and vcvars.bat issuing an error message.

Nahian

@JonB sorry for the late reply, my problem seems different, but the error message is similar to mine.

So my problem is: I am using a basic c++ technique just create a text file, but it's always telling me that file not found or cant open. It worked when I downloaded the qt creator for the first time, but now it doesn't work. The common error message was "System Cannot Find Path Specified" I am going to upload a video about the problem and send the link here so you can see everything.

@Nahian
Sorry, don't have time to watch a 5 minute video. You are supposed to paste a minimal example of any code which goes wrong.

If you get the message "System Cannot Find Path Specified" it means exactly what it says: the file path you handed to it, probably to open for reading (you sure you are creating a file not opening a file??), cannot be found. Either you are passing an absolute path to a file which does not exist or, most likely, you are using a relative path. And since you don't know what directory that is relative to you must not do that, and must make a suitable absolute path to the file, e.g. with the help of QStandardPaths Class. Or you might use Qt resource paths if you want to supply a file embedded in your executable.
