Re: [fpc-devel] FPC 2.0.0 vs FPC 2.0.2 (div by zero)
Den Jean wrote: Hi, I have a strange problem. My Qt4 demo program worked fine with FPC 2.0.0, but crashes (div by zero) with FPC 2.0.2. Debugging shows that indeed a div by zero is done within the Qt4 lib. However with FPC 2.0.0 or using C++ code the library isn't bothered with the div by zero. When I use FPC 2.0.2 however it is. Maybe it was FPC 2.0.0 bug (that was fixed in the meantime) that caused this SIGFPE inside qt to be ignored ? AFAIK it was always the intention of FPC that if used library causes a signal like SIGFPE, this signal *will not be ignored* and will cause our program to fail with some exception. Maybe you can workaround this with Set8087CW, just like it has to be workarounded for OpenGL under Windows (see [http://www.freepascal.org/bugs/showrec.php3?ID=3955]). Just add Set8087CW($133F); at the beginning of your program (or even right inside qt unit initialization) and see if it helps. (Note that I'm writing this without any knowledge of qt or your testcase --- I just thought that it may be helpful, sorry if it's not relevant :) ).

This is a wiki document that contain more explanation, images and has a place for user comments. It is currently not possible. The reason is that fpdoc can also be used to generate PDF or Latex or plain text or RTF docs, and these don't support links. Actually, PDF (and latex package hyperref) support links. Both to other PDF and HTTP iirc. ... and RTF probably supports links too, I guess. So what is left is plain text, and that just needs some sensible way how to mark references.

Re: [fpc-devel] OS aware RTL proposal
Op Fri, 10 Mar 2006, schreef Ales Katona: http://www.freepascal.org/wiki/index.php/OS_aware_RTL Tell me what you think I don't like to do the abstraction at the syscall level, but one level higher, i.e. the Tstream implementation. The reason is that the operating system abstraction happens at this level: - OS abstraction wis present here. - Emulating missing system calls is often much more inefficient than a higher level workaround. Adding an extra layer of abstraction without a good technical reason greatly increases the danger of overdesign and code bloat.
