I've got some troubles with pthread_cond_init when calling it in class
members. After this action next calling of class constructor for second
object bring to SIGSEGV. When I tried to use Object instead Class all seems
fine, but for my task Object not approach. What it can be?
program
{TCondv}
constructor TCondv.Create;
begin
pthread_condattr_init(CAttr);
pthread_cond_init(Cond, CAttr);
end;
I never used pthreads, but looking at the constructor of TCondv, it seems to
require CAttr and
Conv to be setted before calling pthread_condattr_init and pthread_cond_init.
No, pthread_condattr_init and pthread_cond_init initialize variables CAttr
and Cond. By the by, this code written in C work right.

{TCondv}
constructor TCondv.Create;
begin
pthread_condattr_init(CAttr);
pthread_cond_init(Cond, CAttr);
Can this error caused by wrong work of fpc compiler or linker?

You may try this version of your program
-
program Project1;
{$mode objfpc}{$H+}
uses
UnixType,pthreads;
type
TCondv = class
private
Cond : UnixType.pthread_cond_t;
CAttr : UnixType.pthread_condattr_t;
public
constructor Create;
I wonder if this might be a useful read to the architects here.
