Re: pthreads in YahooPOPs
OK Thanks! All future messages will go to the mailing list only. I have had some success with SaveMyModem and the cygwin port of YahooPOPs since these messages. I was able to comment out the pthreads portion and add a few other minor changes, Makefile tweaks, etc. After a bit of work, I was able to compile and build the latest YahooPOPs for Linux on Cygwin. I was able to get some success as well, downloading a single message from my Yahoo! Mail account into SaveMyModem. There were some obvious bugs but the proof of concept is there. Now its just fault isolation and debug. (If you want more of the details, visit the URLs below.) Good News! I suspect that the code snippet is a result of a problem on the original authors OS that is not present in Cygwin. I am able to get full or near full functionality without these nonportable modifications. I think the way to handle this and other changes to the code as a result of the Cygwin port is to just add in #ifdef/#endif around this section like any other port. I passed your comments on to the YahooPOPs forum so hopefully the author can eliminate these nonportable sections and make porting to other architectures that much easier. Thanks again for your help!

Single Unix Specification (http://www.opengroup.org/onlinepubs/007908799/) is a standard cygwin is trying to conform to. They have all needed reference information online. Additionally, would you please keep the answers on-list? I deliberately set 'Reply-To:' to point to mailing list, because i read it along with my personal e-mail, so i don't want to get duplicate copies of one message.

pthreads in YahooPOPs
Hi,
I am trying to build YahooPOPs for Linux
http://sourceforge.net/projects/yahoopops
on Cygwin but have run into a problem with pthreads.
The lines below do not compile even though Cygwin
supports pthreads and pthread.h is included in the
header file.
lock.__m_reserved = 0;
lock.__m_count = 0;
lock.__m_owner = 0;
lock.__m_kind = PTHREAD_MUTEX_TIMED_NP;
lock.__m_lock.__status = 0;
lock.__m_lock.__spinlock = __LT_SPINLOCK_INIT;
Does anyone know why these pthread commands(?) are not
supported or won't compile?
Thanks in advance for the help!
Andrew Lynch
PS, I am also helping the author of SaveMyModem debug
that software. It now builds under Cygwin and many of
the bugs have been found and fixed. Give it a try,
(cvs version only). Hopefully, version 0.14 will be
out soon and much improved.

Re: pthreads in YahooPOPs
Egor, Thank you for the info! I will post it to the YahooPOPs for Linux development forum and see what happens. Hopefully, the author will see the issue and rewrite the code in a more portable manner. Can you deduce what the YahooPOPs author is trying to do? Would you suggest a more portable method I could look at? I will likely be finding or writing a replacement for this code section and appreciate any tips.

The project you're talking about is using non-portable method of dealing with pthreads. Pthread interface doesn't specify an internal structure of pthread primitives, so their actual implementation may vary (and does vary) between different systems. You should ask YahooPOPs people to use portable constructs so that their code can be compiled on any system which supports pthread interface.
