I still get this with BCC32:

Did you find a solution? Sorry, I don't remember... :-(

Enrico,
I am confused. With which BCC version (please gett the info from the
command line)?

Any news about this problem? BCC32 7.70 does not have modff in any of
its libraries, as far as I can see. So it can't be used.

This is working fine:
#include <stdio.h>
#include <math.h>
int main()
{
   float i, f;
   f = ( float ) modf( 123.456, ( double * ) &i );
   printf( "%f %f\n", i, f );
   return 0;
}

I propose to "fix" contrib\hbhpdf\hpdf_utils.c as above and forget the problem till the next hbhpdf update (I can do it). Please confirm.
Enrico,
Something MUST be wrong with your BCC 7.70 insttallation. modff() is a standard <math.h> function, at least since 7.30.
We need to bettter understtand this issue.

This is my test code:

#include <math.h>
int main()
{
   float i, f;
   f = modff( ( float ) 123.456, &i );
   printf( "%f %f\n", i, f );
   return 0;
}
And these are the results with BCC32 7.30 and BCC32 7.40:

Please, look what is in math.h:
#if defined(__clang__)
[...]
float      _EXPFUNC modff(float, float *);
[...]
So I presume you are using bcc32c.exe or bcc32x.exe, aren't you? I need
a solution for bcc32.exe. And I still don't understand why not using the "normal" modf() function.

Enrico,
The official distributtion of BCC 7.30 (and I assume 7.70) does NOT
have bcc32.exe t only has bcc32c.exe (command line compatible with
legacy bcc32.exe) and bcc32x.exe - BOTH are CLang based C11 conformant meaning they both support modff().
Please make sure tto download tthe OFFCIAL FREE BCC 7.30 from:
https://www.embarcadero.com/free-tools/ccompiler/free-download
It is a ZIP file which should be extracted to \bcc102
FWIW, if you have it then there is no need to settup annything and you
should be able tto just type 'make_bc all' in your xharbour root folder
and you should get core and all contribs tto build without any error.
This is my setup.

This is not true! Maybe Embarcadero could have recently changed the
contents of their free packages but it is in the full commercial
packages. And in any case, this is not enough to simply ignore the
existence of bcc32.exe. You have added support for BCC55 (a very old version!) and want to ignore the latest one?

The point is not to select a compiler that can build xHarbour but fix xHarbour to be built by a specific compiler.

Of coursse, except I have no clue WHICH compiler that is. You said Free

Enrico, my official insttallation did NOT include bcc32.exe only
bcc32c.exe and bcc32x.exe
please run your bcc32.exe and tell me which VERSION it is.
Also please provide tthe content of bcc32.cfg.
Since we don't have auto detection for bcc32.exe beyong version 5.8
(please see find_bc.batt) then it means that you must specify
INCLUDE and LIB folders manually - please provide that info too.

Yes, but that is the free version. The commercial version includes also bcc32.exe (not CLANG).

Yes, I always specify them, even with the old build system.
Thanks Enrico, how are the LIBs resolved - I do not see any -L in the
.cfg.
Ok, now that its clear that the bcc32.exe is part of the same
disttribution that include the conformant bcc32c.exe I am sorry butt I
do not see any reason to support the legacy bcc32.exe. The ONLY way to
get that legacy compiler is along side bcc32c.exe which we [auto]
support.
FWIW Embarcadero itself aparantly gave up on that compiler or it would
have been updated.
At least I can adopt a local solution: a little program that "fix" the
code on the fly replacing modff() with modf(), to be run before BCC32
build starts.
I found a better solution: I fixed BCC32 math.h adding this at the end:
#if !defined( __clang__ )
#define modff( f, i ) ( float ) modf( f, ( double * ) i )
#endif
Now BCC32 (not CLANG) can use modff() without problems.

No, they are not. Otherwise my bcc32.exe 7.70 of 2023 would not exist.

If they did not, and its missing support for modff() of C99, maybe its
just a bug that you should report to them. Do they list anywhere the standards supported by tthe compiler?
