I am trying to implement multi-threading in my application(Linux
x86_64)
for this i added -dUseCThreads to my custom compiler options
also added:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i {$ifdef
unix}    cthreads, cmem,  {$endif}
got error so i tried with:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i {$ifdef
unix}{$ifdef UseCThreads}    cthreads, cmem,  {$endif}{$endif}
but i keep getting same error:

QuoteProject project1 raised exception class 'External: SIGABRT'.

 At address 7FFFF6F43D7F
assembler marks:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
00007FFFF6F43D7F 488b8c2408010000         mov    0x108(%rsp),%rcx
and GDB is not being nice to me
any ideas? if i need to debug this further, can someone point me in
the right GDB documentation?

Thank You

Try to put cmem first, then cthreads after it.

i get the same error still

i should add that there is still NO multithreading code, i just added
cthreads, cmem and the error came up.

Are you adding those units in the main program source?
Can you test that does simple console/terminal program crash?

i will try to add this refs to a new console project and report
back...

Well, Linux + console app + debugger (+ threads) is not currently very
strong feature of Lazarus, however, my threaded console apps works ok
with such lpr header:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
progxxx; {$mode objfpc}{$H+}   {$IFDEF UNIX}cthreads, cmem, {$ENDIF}
Classes, ...; begin  
Try to tweak Run parameters -> launching application.

Well i just started a new console application and it had cthreads
refference added already and compiled just fine, i noticed that cmem
was missing, so i went to my project and removed cmem from the
refferences and now the problem is gone, so i guess cmem was causing
the external sigabtr exception,
will i have a real problem for not using cmem? should i keep looking
into a way to be able to use cmem?

Generally no, but please search wiki and forum about cmem.
