[Flightgear-devel] A Japanese Magazine will introduce FlightGear for Mac OS.
Hi there, A Japanese magazine editor sent me an email to ask for permission for introducing FlightGear Mac OS X in their magazine Mac 100% with DVD including the full package of 1.0.0. As long as I know, this will be the first magazine that introduces FlightGear on Mac platform in Japan. I don't know anything about the content of the article yet, but brief introduction, installation, and a few screenshots can be expected. The magazine will be published on May 13th, and I do look forward to getting a sample copy. I wish many Japanese people, especially Mac users, will be interested in FlightGear by this.

[Flightgear-devel] [patch] Get rid of pthread
Hi,
First, let me thank you all for the great work you've done with FG.
I started cross-compiling FG using the great fgfs-builder from Ralf and
I have to say that it helped a lot. However, I had to patch the source
code to make it possible. Here is the first one which basically replaces
SGMutex by OpenThreads::Mutex and allows to get rid of pthread.
The other patch is mainly not mixing winsock with winsock2 and changing
ifdefs. Sometimes there is _MSVC_VER, sometimes __MINGW32__ etc... for
the same thing. I didn't want to provide the patch now since I think
there is a better way. ffmpeg began to move all the platform-specific
code in 2 files called os_support.c and os_support.h. I think this way
help people focusing on what's important. Do you think it's a good
idea ? Do you have other ideas ?
Regards
Benoit

Hi Benoit, I just want to jump in and point out that the threading code in FlightGear and SimGear is very intricate and refined over much time, blood, sweat, and tears. In addition, any little changes surrounding the thread management or the contents of threaded code can easily introduce very subtle bugs that aren't encountered very often and are tremendously difficult to track down. Not knowing anything about open-threads, I'm just a little nervous about any changes to FlightGear's thread system. If OpenThreads has identical functionality to pthreads, perhaps this can be done transparently with no risk to functionality or future robustness ... however, I hope that we proceed very carefully, with much prior discussion and testing. This is an area where a commit now, test later philosophy could hurt the project because thread related problems can be so nasty to debug.

Re: [Flightgear-devel] [patch] Get rid of pthread
This is an area where a commit now, test later philosophy could hurt the project because thread related problems can be so nasty to debug. Maybe I should have stated that I didn't know if it was robust. I surely agree with you that this patch should be for testing purpose only. I posted it since I've used it for 2 weeks now and had no problems. Again, I'm no threading expert but I thought some people would be interested by a first draft.
