Problem with path environment variable

perdrix · Dec 2, 2024

I have installed flex, bison and gperf to C:\Program Files(x86)\GnuWin32\bin and that directory has been added to path:

Code:

D:\Github\qt-build>path

'flex' is not recognized as an internal or external command,
operable program or batch file.

D:\Github\qt-build>bison
'bison' is not recognized as an internal or external command,

clearly Windows 11 is choking on the long path variable????? Bets on 2048 bytes?

Is there any solution for this?

How To Add/Edit Path Environment Variable In Windows 11

In this article, I will let you know about ways by which you can add or edit the path environment variable in windows 11.

I'm not sure this is okay in a path environment variable:

[COLOR=rgb(184, 49, 47)]C:\Program Files(x86)\GnuWin32\bin;[/COLOR]

Try removing the color attributes. That is, change it to this:

C:\Program Files(x86)\GnuWin32\bin;

You also have duplicates. A path only needs to be in the System path or User path, not both. And it looks like some installers did not normalize case when checking if a path is already added. Here are the dups I spotted (there may be more):

C:\Program Files (x86)\IVI Foundation\VISA\WinNT\Bin;
C:\Program Files (x86)\IVI Foundation\VISA\WinNT\Bin\;

C:\Program Files (x86)\Visual Leak Detector\bin\Win32;
C:\PROGRAM FILES (X86)\VISUAL LEAK DETECTOR\BIN\WIN32;

C:\Program Files (x86)\Visual Leak Detector\bin\Win64;
C:\PROGRAM FILES (X86)\VISUAL LEAK DETECTOR\BIN\WIN64;

C:\WINDOWS;
C:\WINDOWS;

C:\WINDOWS\system32;
C:\WINDOWS\SYSTEM32;

C:\Windows\System32\OpenSSH\;
C:\WINDOWS\System32\OpenSSH\;

C:\WINDOWS\System32\Wbem;
C:\WINDOWS\SYSTEM32\WBEM;

C:\WINDOWS\System32\WindowsPowerShell\v1.0\;
C:\WINDOWS\SYSTEM32\WINDOWSPOWERSHELL\V1.0\;

There's also a good chance you've got paths in there that are no longer needed.

Don't forget to add the space before "(x86)". For the Visual Leak Detector, you're adding both a 32-bit and 64-bit path. It's highly unlikely you (or your tools) are using both variants at the same and can drop one of them.

I recommend RapidEE tool, for managing such a complex list of PATH's.

Good catch!

I highlighted the directory in path to show that it was there, the colour stuff isn't in the setting of path.

I de-duped a number of things after my initial post. Good call about the missing space before (x86) - that makes a difference!
