Solve : Problem with a long PATH; PATH question :)? |
| Answer» <html><body><p>hi, I'm trying to create a file via Command Prompt and the program's file creation works grand when it is run from it's directory. However, when running from any directory... using PATH... it prints:<br/>gcc: error: CreateProcess: No such file or directory<br/><br/>The problem, I believe, has to do with it trying to use the PATH to locate cc1.exe. The PATH folder containing cc1.exe is: "C:\Program Files (x86)\mingw-w64\i686-8.1.0-win32-sjlj-rt_v6-rev0\mingw32\libexec\gcc\i686-w64-mingw32\8.1.0"<br/><br/> Now my questions:<br/><br/>1.) Is there a limit on the number of files that windows will search through to find the exe? Some of the PATHS' folders contain many files.<br/>2.) Is that PATH folder correctly set up? There must be something wrong... it's the correct folder... just checked it again. (I learned from windows.com that \\?\ allows a directory path to be longer than 256 characters... and I had "\\?\C:\Program Files (x86)\mingw-w64\i686-8.1.0-win32-sjlj-rt_v6-rev0\mingw32\libexec\gcc\i686-w64-mingw32\8.1.0" but removed the \\?\ just now because that directory path is less than 256 characters.)<br/><br/>edit: Just want you all to <a href="https://interviewquestions.tuteehub.com/tag/know-534065" style="font-weight:bold;" target="_blank" title="Click to know more about KNOW">KNOW</a> that I have enabled long paths and file names via edits to the registry. It should work. But, it doesn't; I don't understand why.<br/>mingw-w64 would install to C:\Program Files, not C:\Program Files (x86).With long path names it is easy to make a mistake.<br/>He can search for:<br/><strong>how to Shorten PATH</strong><br/>And find some tips that might help.<br/><br/>Some programs can be moved to another place if the DLL files come along.<br/>Also, he can create a 'dumb' drive partition is a kind of alias for a specific directory.<br/><br/>Just trying to help.

Specifically, I'll look into creating a 'dumb' drive partition as an alias for that specific directory... thank you so much! I've never heard or thought of a 'dumb' drive partition.<br/><br/>edit.

That is, the variable which is a string, a list of folders where the system will look for executables, by default starting C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem; (there are more folders, usually.) if you have totally replaced everything else, and just have that long folder path on your PATH, all kinds of trouble will happen.<br/><br/>Is that what you meant?

The mingw-w64 project is a complete runtime environment for gcc to support binaries native to Windows 64-bit and 32-bit operating systems. The -w64 doesn't mean it's 64-bit only.<br/><br/> Quote from: Salmon Trout on January 29, 2019, 02:04:36 PM<blockquote>The convention is to write PATH in capital letters when you are discussing your system's PATH environment variable.

Thank you for the video too. It never occurred to me that <strong>gcc</strong> would have its own rules about file names and directories. hmm...<br/><br/>ooh: Their installer created the directory and I would imagine the mingw-w64 installer wouldn't commit suicide... but, I'm definitely not an expert; just trying to install this correctly. <br/><br/> Quote from: Salmon Trout on January 29, 2019, 03:54:44 PM<blockquote>It's a name.

That and 64bit processors are comfortable with running 32bit applications... and after learning that I could install a 32bit version, I was sold. Thank you so much Geek-9pm! I followed the instructions on the video you linked and everything works now! After downloading and installing the mingw-get-setup.exe, I removed the two directory paths I had added to my PATH before adding the simple path the video told me to add... and it works excellently now !in any directory! <br/><br/>note: in case anyone's windows 10's right click on start menu and then clicking System-doesn't bring up the correct window... click start and begin typing "Control Panel"... run that app and click "System" <br/><br/>edit: Yes, I realize that this is the mingw last updated in 2013, but it works extremely grand so far... so I'm happy. I'm keeping mingw-w64, for right now at least. <br/><br/>And... above I said that I had downloaded mingw-w64 from mingw's site... but, sorry for my mistake, I think I actually chose the mingw-w64 site when both were shown in duckduckgo since mingw-w64 is <a href="https://interviewquestions.tuteehub.com/tag/newer-2866961" style="font-weight:bold;" target="_blank" title="Click to know more about NEWER">NEWER</a>.
