Hi,

I have a need to use pthreads in a CW 8.3 bundle I am creating, but I
cannot find where the docs are to tell me what headers and libs I need
to include.

Can someone point me to where I can locate this information?

Thanks

All you need to include is <pthreads.h>. This assumes that you have
/usr/include on your system include path. If you are using the MSL you will
encounter some header conflicts that you will need to resolve. If you have
more specific questions I would be happy to answer them.

If you want to use pthreads, you'll need to go BSD all the way with CW
8.3.

the release notes show how to do this but off the top of my head...

In the access path move the MSL access path below the /include and /lib
and the Mac OS X folders so it is lower in the access paths.

Change your precompiled header so it is the version without MSL in it..
i.e. instead of MSL MacHeadersMach-O.h it would be just
MacHeadersMach-O.h

For the libraries change from using MSL_All library to
MSL_Runtime_Mach-O.a (and if you are using MSL C++ the MSL_C++_Mach-O.a
should be added.

The release notes talk about using the BSD headers, take a look at that.

Thanks for the info.

I've searched the release notes section and come across some
references to BSD headers/libs in projects, but I am not certain if
they are what I need.

Possibly I don't have them installed? Is there a specific filename
for release note that you are mentioning?

Thanks

If you have the XCode Tools (or Apple Developers Tools for OS X 10.0 -
10.2) then you have them isntalled. If you don't have the Developer
tools installed you can't debug with CW or make Mach-O applications.

Basically if your search path searches for /usr/lib and usr/include
before searching for MSL it uses BSD. If it searches and FINDS the MSL
folder before it searchs the /usr/lib and usr/include then it uses MSL
instead and in practice should use BSD for anything not included in MSL.

The only problem happens when you have something such as pthreads that
are declared in a standard header. such as stdio.h this was more a
problem in 8.3 than in CW 9.

Pardon my butting in, but...

I am using CW 7.2 on Panther. I am trying to use BSD socket calls in my
code. I tried to add MSL_Runtime_Mach-O.a to the library list for my
project as mentioned in this thread, but the file is greyed out in the
"Add files to Project" dialog.
How can I add this file, or is it not compatible with 7.2, or is there
another way to get the accept/bind/listen functions linked in?

All bets are off, I can not recommend that and Metrowerks does not
support CW 7 running on an Operating System that is two generations
newer than what it was developed and released on. We are good but not
psychic :)

It is often that way when the file is already in your project. Be sure
it isn't added already. it will aslo be greyed out if you have the
wrong type. The other reason would be if it was a PEF program and not
Mach-O program

If you are doing Mach-O it should be allowed. I don't believe we had
MSL C and it was Apple's linker ported to our tools with CW 7 Mach-O so
this all should work, no extra needs for BSD.
