Hi John,

Right click in any open area of the controls line to set the Alert time to the current system time.

Thank you for taking the time to implement this feature.

I hope you don't mind that I acknowledge your assistance in the help file.

No problem at all! In fact, thank you. I do the same when a user reports a bug to me regarding WinContig.

Marco

Try it once with Admin account, if it check file like sysdefs.tag

An old Depends.exe might show if it fails with files.

Beginner questions / Unresolved External Symbol

Last post by StevenCooper - July 19, 2026, 08:15:51 AM

I recently moved from a Windows 10 computer to a Windows 11 computer; I had previously been using Version 10 of Pelles C, but it wouldn't work in Windows 11, so I "jumped" all the way up to Pelles C Version 14.5.

Two programs I "test" compiled under version 14.5 compiled and linked just fine, no problems.

But a third program, that compiled just fine under version 10, is now getting the following error message under Version 14.5:

POLINK: error: Unresolved external symbol '__stod' - referenced from 'C:\Users\steco\Documents\Pelles C Projects\LotteryScratchOffs\output\LotteryScratchOffs.obj'.

I have searched this forum for information about this, but found only one refernce to it from 12 years ago.

I have also search the Internet and can find no information about this '__stod' symbol.

Can somebody help me, please?

I am running Windows 10. I installed PellesC in an Admin account for everyone but I am trying to use it under a non-privilege account.

[C:\Program Files\PellesC\Files\BBBBuilder_PS - Copy (2)]

Sage advice IF one uses various Pelles C tools outside of the IDE.

However if staying within the IDE I've never had an issue with installing Pelles C into directories with spaces, all the way back to at least Windows ME  .

My current install path C:\Program Files\PellesC_14_5\
My current source code path C:\Program Files\PellesC\Files\
even a path like C:\Program Files\PellesC\Files\BBBBuilder_PS - Copy (2) works without any problems.

I've never had Windows Defender flag Pelles C neither has my GData antivirus program. Although we've heard many stories about the 'free' antivirus programs flagging Pelles as well as programs built by Pelles C.


So just another viewpoint -

There is not enough information to be able to help Pablo until he posts more IMO.

Hi Pablo,

For 20+ years, I've kept C:\Pellesc\ in the root of my drive and I tell
Windows to exclude that folder from Windows Defender wanting to scan it.

I never have problems using Pelles C with that arrangement.

The main thing is: DO NOT use spaces in your folder name.

Hi Pablo,

Kindly, what is your operating system? Is the User Access Control enabled? Do you have any antivirus software? Are you operating under an administrative account?

Hi PabloMack,

Welcome back - I believe.

Not a lot of information provided - Error 2 is file not found.

Have you checked the shortcut properties?
Have you looked in "Program Files\PellesC\bin" for poide.exe?

I just did a clean install - worked fine.  Windows 11, 25H2, 64bit of course.

You might just try uninstalling and re-install after re-downloading from
https://www.pellesc.se/

It has been years since I ran Pelles C so I installed the most recent release and I get the following message after trying to run poide:

Unable to start POIDE.EXE (error code 2)
