Re: [fpc-pascal] WinCE multithreading
Hi! I submitted two patches that solves multi threading issues on WinCE (one on Lazarus LCL, other on FPC RTL) http://bugs.freepascal.org/view.php?id=18756 After the patches, all examples works as expected.

Re: [fpc-pascal] WinCE multithreading
Hi! I made some changes for WinCE and want test. How I rebuild only the RTL on windows? I'm using WinXP, Lazarus 0.9.30.1 with fpc 2.4.4 + cross-arm downloaded from daily snapshots.

Re: [fpc-pascal] WinCE multithreading
Yes, I don't use this. I access the LCL methods via TThread.Synchronize, On my mind, I'm doing this right... Correct me if I'm wrong. The bug related tells that TThread.Synchronize don't work as expected in WinCE as in others OS's. It has two examples that don't work as expected on WinCE, both with threads and Critical Sections.

You cannot use the LCL from other threads ... use LCLIntf.SendMessage instead and handle the message in a procedure in your window. I just commited some more explanations about SendMessage in the docs.

Re: [fpc-pascal] WinCE multithreading
Yes, the current FPC has this feature. Maybe the problem with WinCE with multithreading is this: http://bugs.freepascal.org/view.php?id=18756 and not the use or not of Unaligned keyword. Added with some outdated documentation on Wiki, this cause a little of confusion in the mind of who starts with WinCE with a multi-thread application. I changed the issue. Testing now to see how it works.

Re: [fpc-pascal] WinCE multithreading
But is the unaligned still required? I remember that unaligned access was sure crash in WinCE many years ago, but I vaguely remember someone mentioned that FPC had improved it's support for the compiler figuring out on it's own when something is unaligned. While doing Android development for example, I haven't yet had a single crash due to unaligned access ... and I made no use of this keyword so far. -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

If the record the pointer points to is stored at a potentially unaligned address, you need unaligned(myrec^.member). If both are the case, you need unaligned(unaligned(myrec)^.member) I'm fairly certain that unaligned(myrec^).member won't do anything.

Re: [fpc-pascal] WinCE multithreading
I'm debugging and I have doubt: I'm using records and pointers to records. On WinCE wiki, the use of unaligned only shows with pointers to integer. And with recods, I must do unalinged(myrec^).member or unalinged(myrec^.member) ???

Some time my application hang when synchronize to log or access the gui, but i sloved it by reduce info passed to the gui, or do no pass any object that created by threads or other threads to the main thread. You can descript your problem to the FPC team when you have it.
