ZThread

Should anyone experience the same problem as the previous poster: under Mac OS, you need to link your program against the carbon framework for ZThread to work properly.
Example:
g++ -o test test.cpp -framework Carbon -lZThread

Zthreads on Mac OS X
I created a simple C++ program on Macbook Pro (Leopard

10.5.6) to play with the ZThreads open source framework. I

downloaded the ZThread 2.3.2 source from sourceforge and

compiled it (eg.. ./configure -> make -> make install). I

built my test application using Eclipse and linked the

ZThread.la library into my application. The application

compiles/links successfully but when I try run my application

within the Eclipse IDE, I get the following errors:

dyld: lazy symbol binding failed: Symbol not found:

__MPIsFullyInitialized

Referenced from: /usr/local/lib/libZThread-2.3.2.dylib

Expected in: flat namespace

dyld: Symbol not found: __MPIsFullyInitialized

Referenced from: /usr/local/lib/libZThread-2.3.2.dylib

Expected in: flat namespace

Any ideas on what could be causing these errors????

Re: Won't Compile
See diffs required here:

I've done them and it compiles fine on g++ 3.4.6

Is ZThreads really dead? I'm trying to contact the author to find out. Thinking in cpp has a good introduction to the library.

I'm going to give ZThreads a good work out as I need a thread library for a commercial project and don't want to write my own again. Be interested in other people's experiences.

Given that the last release was in 2003, I'm not holding my breath for an update.... ;-)

New g++ requires strict definition, this function is considered anonymous since the one intended is inherited.
What you should do is replace:
isDisabled()
With
LockHolder&ltLockType&gt::isDisabled()
