Re: [fpc-pascal] FPC 2.6.2 for DOS/Go32V2 FP.EXE cannot run a second time
In our previous episode, Sven Barth said: and it works. I tested only FP.EXE, not RTL units. It seems that the error (FP.EXE cannot run) was corrected. Thank you for your help. Expected question: when the new version 2.6.3 will be available? Hmm. I thought the next version was going to be 2.7.something? 2.6.3 and 2.7.1 are development versions. The next release is likely to be 2.6.4 somewhen in the near(?) future. After that the next release is likely to be 2.8.0. To get an idea of the versioning, it is easiest to look at the picture in the FAQ: http://www.freepascal.org/faq.var#versions and read the text above it. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

RE: [fpc-pascal] FPC 2.6.2 for DOS/Go32V2 FP.EXE cannot run a second time
Could you try to delete the files generated by fp.exe before restarting it: fp.exe generates three files: -fp.ini -fp.cfg and fp.dsk Try first to only remove fp.dsk and see if it cures your sigsegv or not. fp.dsk is a binary file that contains configuration information that mighr be corrupted. If remove fp.dsk alone does not remove the crash, try removing the three files. Could you please report to the list if any of the above helped?

Re: [fpc-pascal] FPC 2.6.2 for DOS/Go32V2 FP.EXE cannot run a second time
Currently I'm quite busy but definitely I will try it and let you know. Thank you.

Can you tell me where can I download source for IDE from FPC 2.6.2 and how to compile it? I will try it when I have a free weekend. See links on http://www.freepascal.org/develop.var - you can e.g. try downloading fpc.zip source package for fixes from FTP. Unpack it somewhere and run: make rtl_all packages_all ide_all OPT=-gl -O- NOGDB=1 That should compile IDE without the debugging support, but that should be sufficient for start. If the problem cannot be replicated that way, the next step would be downloading the pre-compiled libgdb (ftp://ftp.freepascal.org/pub/fpc/contrib/libgdb/v6.1.1/go32v2-v601.zip), creating directory libgdb next to rtl, ide and packages, unpacking content of the downloaded file there and then compiling again using: make clean rtl_all packages_all ide_all OPT=-gl -O- If that still works, you could remove the -O- bit to see if the optimizations make any difference.

Obviously, the next step would be compiling the IDE with debug information (including -gl) to see where exactly it fails.

Re: [fpc-pascal] FPC 2.6.2 for DOS/Go32V2 FP.EXE cannot run a second time
Yes, I know these DSK-file crashes, but this is something else. Anyway, I deleted the file fp.dsk - SIGSEGV. I deleted the remaining files - SIGSEGV. Always helps run old fp.exe 0.9.2 18.05.2004 from 1.0.11 before run fp.exe from 2.6.2. Both versions use CWSDPMI v7. I still think that fp.exe will something set in the memory and after completion of the program does not reset this. Of course this is only my assumption. When I have the source program hopefully learn more. Anyway thanks for the help.
