Re: C/C++ call to detect cpu?
Nicolas, I have commented assembler code for the intel family of CPU's. This code goes back to the i386 and also takes into account the CPU string, and will calculate the clock speed. I do call this as a library function from c/c++ programs. Unfortunately this is written for Microsoft's MASM, and I have never ported it to gas. If you want a copy I can send you the assembler source code and/or the commented listing as well. -Derek At 05:50 PM 1/22/2006, Nicolas Blais wrote: On Saturday 21 January 2006 15:33, John Levine wrote: Other than 'grep'ing dmesg, is there a way to know the current cpu such as a struct with the machine's cpu and cpu feature (kinda like a time_t struct)? $ sysctl hw.model hw.model: AMD Athlon(tm) 64 Processor 3000+ If you want more details write a tiny assembler routine that does a CPUID instruction and decode the result.

There's also a link from the Gentoo Linux docs somewhere in the handbook, but you will have to hunt that down on your own ;). There's also a better (or perhaps, just more relevant) doc somewhere on FreeBSD's site about CFLAGS and CXXFLAGS which also addresses gcc variables and architectures I think. -Garrett ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: C/C++ interpreter Ch for freebsd
To my fellow geeks and wizards, My dime's worth is that Ch definitely deserves checking out. I've done porting, general development, testing, and more; the one constant I had to do --and I'm pretty sure this holds for all of us-- was cobbling together scripts. Looks like this interpreter can simplify/unify writing shell script. Come in seriously handy for the usual throw-away stuff. Thanks, Gary. Be glad to let you know that we have ported Ch, Ch SDK, Embedded Ch, Ch Control System and SoftIntegration C++ Graphical Library (SIGL) for FreeBSD. Ch can now be freely downloaded from http://www.softintegration.com/download/ Best regards, Xiaodong Xiaodong Zhou, PhD http://www.softintegration.com Ch: a C/C++ interpreter for cross-platform scripting, shell programming, 2D/3D plotting, numerical computing, and embedded scripting. gary On Sat, Mar 13, 2004 at 03:10:45AM -0500, Xiaodong Zhou wrote: On Fri, 12 Mar 2004 04:07:45 -0500 (EST) [EMAIL PROTECTED] (Xiaodong Zhou) wrote: Hello, We have developed a free C/C++ interpreter called Ch.

Re: C/C++ Unix/Programmer/Tester
I'am interesing in becoming BSD tester or alfa tester, how I can get information about job positions in BSD development. FreeBSD is created and developed by volunteers rather than paid staff. To get a job in BSD development, you would have to get a job in a company that is using FreeBSD (or one of the other BSDs) and that, for their own reasons, chooses to have some staff working on BSD things - probably that run on top of BSD. You could also volunteer to do development, but you would not get paid for it from FreeBSD - no one does. To do this, look at the various projects and or the bug (pr) list and do a good job writing the needed code or correction and submit it. If it gets used and you do this often enough you might end up being a committer. As for testing, just download the latest CURRENT and update to the latest with cvsup and you will be running (and thus testing) the latest BSD. Check out information from the FreeBSD web page - follow the appropriate links. jerry Thanks Ricardo Balda ___ ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

RE: C/C++
FreeBSD can compile C/C++ programs, if you have gcc or gcc-c++ installed respectively. And you can link those programs if you have an appropriate linker installed (binutils). Of course an assembler is also needed (which is installed along with binutils). --- On Fri 09/05, Denis [EMAIL PROTECTED] wrote: From: Denis [mailto: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Date: Fri, 5 Sep 2003 10:43:54 +0400 Subject: Hi All!!!brbr Does FreeBSD support C++ or support C only?brbr-- brBest regards, Denisbr[EMAIL PROTECTED]brbr___br[EMAIL PROTECTED] mailing listbrhttp://lists.freebsd.org/mailman/listinfo/freebsd-questionsbrTo unsubscribe, send any mail to [EMAIL PROTECTED]br ___ Join Excite! - http://www.excite.com The most personalized portal on the Web! ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
