Red Hat Cygwin official installation utility ?

What is this versus cygwin-dot-org ? Just tried "Red Hat Cygwin official installation utility" (www-dot-redhat-dot-com-slash-services-slash-custom-slash-cygwin) and their one download site (ftp-dot-ges-dot-redhat-dot-com) suffers from complete autism - i.e., totally unresponsive, ---Jan -- Probl

Re: GCC version 4.3 on Cygwin ?

of answers using MinGW with 4.5. The MinGW results were what I expect - the same as I got using SuSE 11.4 with g++ 4.6. Also, the values I get using VC++ 2010. Haven't had time to wade through the ~1500 lines of Runge-Kutta code to find the needle-in-the-haystack. ---Jan On Mon, Aug 1, 201

GCC version 4.3 on Cygwin ?

The latest version of GCC is 4.6. The version used with MinGW is 4.5. Cygwin uses 4.3. Why is Cygwin 3 versions behind? ---Jan -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe

Thanks! This is an example (from IBM) I cut-and-paste into Emacs to better understand pthread_once(...). Didn't notice the two "%.8x" in printf(). Thanks again, Jan -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: htt

Don't know why all the white space in the code turned intro "?". Hopefully this is better: #include #include #include #include #define checkResults(string, val) { \ if (val) { \ printf("Failed with %d at %s", val, string); \ exit(1);

Pthread question for GDB?

If I'm stepping through main() in GDB, when I step past pthread_create() should the associated (newly created) thread begin executing independently of main() (i.e., the "main" thread)? Executing independently in the background? Red Hat's GDB documentation says: "In all-stop mode, whenever your pro

I went to GNU.org to read about GDB and threads since I'm having trouble working with ptheads under GDB on Cygwin. I notice this on the GNU.org web site: "Warning: These facilities are not yet available on every GDB configuration where the operating system supports threads. If your GDB does not s

G++ 4.3.4 (with Cygwin 1.7) vs.G++ 4.5.2 (with MinGW) ???
