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. Rolf. ^ permalink raw reply [flat|nested] 9+ messages in thread

For example: XAllocColorCells is not working. 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. -- Dennis Clarke RISC-V/SPARC/PPC/ARM/CISC UNIX and Linux spoken GreyBeard and suspenders optional ^ permalink raw reply [flat|nested] 9+ messages in thread

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! Rolf Perau ^ permalink raw reply [flat|nested] 9+ messages in thread

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. ^ permalink raw reply [flat|nested] 9+ messages in thread
