Just search it from a your code.
A macro atof use it in version 10.

Code Select Expand

/* internal stuff */
...
/* macro overrides */
#define atof(s)  __stod(s,0,0)


Code Select Expand

[155]extern _CRTIMP double __cdecl __stod(const char *, char **, long);
[172]#define atof(s)  __stod(s,0,0)
[177]#define strtod(s,endptr)  __stod(s,endptr,0)

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)

Projects developed with Pelles C / Re: Simple Calendar

Last post by John Z - July 17, 2026, 11:32:49 PM

Hi Marco,

Here is a version 2.0.2 that enables setting the Alert time to the current system time.  It does so without using a button, as I don't think it would be used very much, and space is limited without a significant GUI change.  The Alert time is not meant to be another system time clock. I suppose I could 'disable' scheduling unless the Alert time was changed but that seems burdensome to a user.

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

So this may be an interim, or final solution, as I think on it more (after the next big thing  )

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

Thanks,
John Z

Full project sources zip attached. Also attached 7z which is just the program and help file for those that don't want/need the sources.

Bug reports / PoFmt bug

Last post by MrBcx - July 17, 2026, 09:07:36 PM

Hi Pelle,

I discovered 2 scenarios that cause PoFmt to go off the rails ( mostly indentation ).

1) Optional args and 2) initialized variables

Here is a function that shows both after being processed by pofmt using either KR or PO styles.

Code Select Expand


char *join(int ArgCount, PCTSTR Str1, ...)
{
    va_list ap = {
    0
};
PSTR BCX_RetStr = NULL;
PSTR currentStr = NULL;
int i;
size_t totalLen;
totalLen = strlen(Str1);
//  Calc memory reqmnt
va_start(ap, Str1);
for(i=1; i<=ArgCount-1; i++)
{
currentStr = va_arg(ap,PSTR);
if(strlen(currentStr)>0) {
totalLen += (int)strlen(currentStr);
}
}
va_end(ap);
//  Allocate memory
BCX_RetStr = BCX_TempStr(totalLen);
if(BCX_RetStr == 0) {
return NULL; //   Not a good sign :-(
}
//   Init result with Str1
strcpy(BCX_RetStr,Str1);
//   Concat remainiing strings
va_start(ap, Str1);
for(i=1; i<=ArgCount-1; i++)
{
currentStr = va_arg(ap,PSTR);
if((int)strlen(currentStr)>0) {
strcat(BCX_RetStr,currentStr);
}
}
va_end(ap);
return BCX_RetStr;
}
