Linux and unix are already defined for Linux.

Moreover, your method for Linux is flawed, since it only works on linux/x86 (and not compile for anything else) It is doubly flawed because on linux it will include both the linux and the unix code.

Is this code tested at all?

P.s. Do NOT use unit libc for new development:

I don't have Linux or MacOSX here... please test itfor me.

If you delete {$ifdef Linux}{$endif}  parts  and use only
the {$ifdef Unix}{$endif} parts, does it work correctly ?

(all on FreeBSD/x86)

Free Pascal Compiler version 2.5.1 [2010/04/22] for i386
Copyright (c) 1993-2009 by Florian Klaempfl
Fatal: Can't find unit synch used by test
Fatal: Compilation aborted
Error: /home/marcov/bin/ppc386 returned an error exitcode (normal if you did not specify a source file to be compiled)

This is due to writing Synch with capital "S", if I correct it, I get

Free Pascal Compiler version 2.5.1 [2010/04/22] for i386
Copyright (c) 1993-2009 by Florian Klaempfl

synch.pas(97,3) Fatal: Syntax error, ";" expected but "identifier PRIVATE" found
Fatal: Compilation aborted
Error: /home/marcov/bin/ppc386 returned an error exitcode (normal if you did not specify a source file to be compiled)

Apparantly FPC is not put into Delphi mode ({$mode delphi}), if I correct that it fails on "currenttm", windows unit and more:

synch.pas(681) Fatal: There were 13 errors compiling module, stopping
Fatal: Compilation aborted
Error: /home/marcov/bin/ppc386 returned an error exitcode (normal if you did not specify a source file to be compiled)

The errors on 458 and 586 _might_ be related to several handle types on FreeBSD being pointer instead of  (unsigned/signed or long) integer types.

Amine.

IMO this should be part of the library and not of the commandline. each unit may be compiled with a a different mode.

Hello

Yes, i will include it in the unit ...


Are you using Unix or Mac OSX , Marc ?

Can you download vesion 1.03 and compile and test
it for me ?



Amine.

1) filename is still uppercase
2) still need to set mode
3) line 368 has "ttm" instead of "tm".

If I fix that it compiles and appears to run on FreeBSD 8.0/x86

Hello,

I have updated synch module to version 1.04...


http://pages.videotron.com/aminer/

Just to be sure that it is working properly, look inside
test.pas , if you set it like this:

Sem := TSemaphore.Create(1,1); // to 1,1

does the second 'sem.Acquire' enters in a 'wait' state ?



Amine.

Can someone else test the synch module on Mac OSX ?

Hello.
There is progress?
Why Lazarus still has not cross-platform mutex and semaphore  ::) ?

There are several synchronization classes in unit syncobjs.
