Hi,

Many thanks to all, to show me the right way to solve my problem.
I changed all LC_xxx to C in / etc / TIMEZONE.
Reboot the system make all my program. my PROBLEM SOLVED!

Bey the way, the X11 problem in Solaris 10 is known and well described. But I could not find an update for it. CVE-213-1997. But I would like to have a solution.

Thank you ALL!

Re: gcc on Sparc Solaris 8

[rolf perau via gcc-help]

my program has a long history.
Build on Sparc 1, 2 and then Ultra Sparc with
Solaris 2.5 using the Sun Compiler and Debugger. I never had a problem with it.


now ported to Ultra Sparc 10 and also PC.
os is Solaris 10 build with Solaris Developer Studio 12.3
I never had a problem with it.

but in Solaris 10 there are problems with X11 libraries. For example: XAllocColorCells is not working. That's why I am now on Solaris 8. No Problems with X11. Sadly I have
for Solaris 8 no Sun / Oracle compiler and now has to use GCC. bu now I have problems with the flashing of Flotingpoint Values.

I understand it this way, the Floating Point Numbers representaion is nnn dot nnn like 123.456 and never with comma.

A very basic Xlib function is not working ??  Really ??

This ?

      Status XAllocColorCells(display, colormap, contig,
      plane_masks_return, nplanes,
                                pixels_return, npixels)
            Display *display;
            Colormap colormap;
            Bool contig;
            unsigned long plane_masks_return[];
            unsigned int nplanes;
            unsigned long pixels_return[];
            unsigned int npixels;


As for floating point numbers.

Floating point numbers exist in binary with a trivial format of a sign
bit and then some bits for an exponent and then lastly a string of bits
to represent the significand.  The significand ( or mantissa ) data also
has an implied leading bit of "1" for normal numbers.  How you choose to
print them out is entirely your business.

The Oracle Solaris 12.6 Developer tools are a free download and I do
suggest you look at them. I am fairly sure that support for Solaris in
gcc has been dropped as of last year. At least for Solaris 10. Sadly I 
have never seen Solaris 11 in the wild. Maybe that works and maybe it 
does not. Have you considered simply moving over to FreeBSD or even dare 
I say it Linux?  I have heard in various places that this "Linux" thing 
works quite well and I have even seen it running neatly.  Could be worth
a look. :) Just don't go lookng too closely for POSIX compliance or even
cross platform clean compiles.

Hi Dennis, 
int scan_assign_double(ScanFILE *psf, double *pd, void *userdata, ScanFLAG flags){
        char temp[100];

        if (scan_nonblank(psf) == '=') fgetc(psf->fp);
        if (scan_word(psf, temp, sizeof(temp)-1)) return -1;

fprintf( stderr, "Reading the String : %s\n", temp);

        if (sscanf(temp, " %lf ", pd) != 1) {
                error_out(err_scan_expect_double, temp, psf->filename, psf->linum);
                return -1;
        }

fprintf( stderr, "%s %lf\n\n", "After sscanf %lf :" , *pd);

        if (scan_nonblank(psf) == ';') fgetc(psf->fp);
        return 0;
}

Resulting in :

Reading the String : 0.7
After sscanf %lf : 0,000000

Reading the String : 5257.872067
After sscanf %lf : 5257,000000

Reading the String : 152.498875
After sscanf %lf : 152,000000

Reading the String : 12.0
After sscanf %lf : 12,000000

Reading the String : 0.7
After sscanf %lf : 0,000000

This looks pretty obviously related to locales. Your locale expects
',' as a decimal point, but the numbers you are trying to read have
'.' for decimal points. That means sscanf stops reading the number at
the '.' character, because that's the end of the string that matches
the expected format for a number.

In any case, sscanf is not part of GCC, it comes from the Solaris C
library, so this is not a GCC problem.

This is not a GCC problem and not even a Solaris problem.

He needs to simply setlocale first :

      #include <locale.h>
      char *setlocale(int category, const char *locale);

Problem solved.

Put a locale on the command line or just allow POSIX :

     if ( argc > 1 ) {
         printf ("\nINFO : You suggest a locale of %s\n", argv[1]);
         buf = setlocale ( LC_ALL, argv[1] );
     } else {
         buf = setlocale ( LC_ALL, "POSIX" );
     }

     if ( buf == NULL ) {
         fprintf (stderr,"FAIL : setlocale fail\n");
         return(EXIT_FAILURE);
     }

gcc on Sparc Solaris 8

[rolf perau via gcc-help]

Hi all,

I use GCC 4.7.2  on Solaris 8 SPARC and have the following problem...

For example, a text string "1.5" will be changed to "1,000000", or "0.3" will be changed to "0,0000000".


maybe someone can help me to solve the problem, I would be very happy !!!

You should at least provide some sample code.
