Hi all, I have an old C/C++ compiler suite from Zortech, formerly Zorland, later bought by Symantec, later I think dropped. I use it under DOS to compile just one ancient application which still keeps several businesses running.
Under dosemu I have never managed to compile the entire application, the closest I ever got was under dosemu 1.1.5, when 80 out of the 81 modules that make up the application compiled. The remaining module caused the compiler to cause dosemu to segfault, I think partly as it is the largest of the source modules at about 197kB. The next-largest module of 185kB compiled OK. The same compiler executables which ran reasonably well with 1.1.5 now reliably cause dosemu 1.1.99.1 to segfault immediately on running. They don't even get as far as reading a source file. There are real mode and protected mode executable versions of this compiler, called 'ztcpp1' and 'ztcpp1x' respectively. Both are .exe files. The 'x' model executables of the compiler use a proprietary dos extender which was at one time available with the Zortech suite, and later available alone (and somewhat improved) as a product called called X32. The source is not freely available but I have a copy of the X32 product. The real mode version of the compiler runs but the protected mode version causes the segfault. The real mode compiler executable is not capable of compiling my sources because of memory limitations. I compiled dosemu with debugging enabled, ran 'dosemu -D+a -o debug' and ran the two compilers - first ztcpp1.exe and then ztcpp1x.exe - with no command line parameters, just to get the usual compiler usage information message. The resulting debug output is just under thirty- one Megabytes, so I haven't attached it. :) It comresses to just under 91kB with bzip2 so I can send it to anyone who's interested, together with my compiletime-settings and dosemu.conf if required. This is all running on an Athlon1300, I can try it on other machines if that will help, or I can let you have the compiler exectuables, I'm sure Zortech won't mind. The following lines might be of interest. Here are the last lines of the 'debug' file: ---------------------------------------------------------------------- Do INT0x21: Using caller_function() INT21 (0) at f800:4806: AX=6201, BX=1a3b, CX=0000, DX=1208, DS=073a, ES=0b31 int 0x21, ax=0x6201 DPMI: realmode hlt: 0xfc807 DPMI: initializing DPMI: return to dosemu code for handling signals ---------------------------------------------------------------------- The following appears at the end of boot.log: ---------------------------------------------------------------------- ERROR: CS selector invalid: 0x0073, type=0 np=1 leavedos(36|0x24) called - shutting down ERROR: leavedos() called from within a signal context! ---------------------------------------------------------------------- It's not a big deal for me that I can't compile this package under dosemu, so I'm not worried about not getting a reply, but I thought you might want to know that things in the dosemu/DPMI world still need some attention. If you want any more information please let me know. 73, Ged. - To unsubscribe from this list: send the line "unsubscribe linux-msdos" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
