Thanks, this definitely helps at least the reason why it is breaking.

You know, that little 'daemon that does nothing' but spawns 64 processes, just to be sure. If you are not: why do you need 255 threads ???

Please > help... The bug is actually solved: now you see an exception when a thread cannot be created (before the bug was solved you couldn't know if the thread was successfully created or not). As per the solution to the maximum number of threads, you can look here: http://stackoverflow.com/questions/481900/whats-the-maximum-number-of-threads-in-windows-server-2003 it seems the limit is due to the available memory and the stack used by each thread.

[fpc-pascal] make install
Hi, For developers that use FPC sources from SVN, like me, I ask: 1. There are some advantage to use 'make install' to compile FPC? Which? 2. There are some advantage to install (make install) in a directory different of the sources? Which?

Of course it matters! 64 bit doesn't works in OS 32 bit. That is my problem. I'm configuring a HD external with my all environment. > 3. Install everything to the same prefix.

OK, I will try. Looks like that is I want. But which magic "CROSSINSTALL=1" does? Do you have a link where I can study more about it?
