[opensuse-programming] Linking to libraries of different compilers

by Verdi March

Hi, Is it safe to link an application against libraries compiled with a different compiler? For example, to compile Linpack using gcc, and then to link with static libraries (libacml_mp.a and libmpich.a) compiled with PGI. My presumption is that it is safe to do so, since objects/libraries in Linux (SLES9) must follow a certain format (ELF?). But with my shallow knowledge in compilers, it's better to ask to this list.

[opensuse-programming] Cross Compiler Tutorial

by Jorge Almeida

Hello to all. I'm using openSuse (Suse 10.2). I'm interrested in having an environment of cross compiling using some old versions of GCC, specially GCC 2.95 and GCC 3.4. Does anyone knows a good tutorial, or build instructions to set these environments? Any clue will be a good help. Thanks to all. Best regards. -- Jorge Almeida j-almeida(a)criticalsoftware.com --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-programming+help(a)opensuse.org

Re: [opensuse-programming] Kernel update

by Nenad Stojnic

Hi. Thx. man. Greate links ... especial first. Im suse 10.0 my mouse go crazy in moments. I get message in my system log: psmouse.c: bad data from KBC - bad parity Then I found after "google-search" that error about I wrote above come from bad kernel code. That`s only reason why I should to compile and install new kernel. I am obstinate and I wan`t to lose my suse 10.0 because I have a lot good software installed on it. I will try with this documentation and suse kernel rpm to resolve my problem. This problem is serious because mouse make unpredictable actions. Thx. again.

[opensuse-programming] Kernel update on SUSE 10.0

by Nenad Stojnic

Hi. I need help. I have SUSE Linux 10.0 with kernel 2.6.13. Now I want to update kernel to last stable version. I need answer on next question: 1. Can I use last kernel version from official linux kernel site for update? 2. When I get kernel, does I need todo some special action before update? 3. I found on net some introduction for update kernel. Does exist some tutorial for manual SUSE update kernel? p.s. I must manual update kernel beacuse I don`t have Internet at home. Tnx so much. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-programming+help(a)opensuse.org

[opensuse-programming] A request for your input.

by lmth＠deakin.edu.au

Hello My name is Lara Thynne and I am a PhD candidate at Deakin University Australia. I am currently researching the boundary between work and leisure activities directly related to the open source community and open source program development. As part of this I am running a survey at the following address. https://dcarf.deakin.edu.au/surveys/oss/ The survey is completely confidential and looks at your views and motivations to use Open Source software and to participate in the community. It will only take a five to ten minutes to complete and your contact details will not be recorded. You can withdraw your participation at any stage. I sincerely apologize for the spammish nature of this e-mail - I don't mean to abuse this list. I am trying to collect responses from as many open source developers and users as possible and a mailing list like can be the only way to reach many developers. Thanks again Lara P.S The program that I am using is open source, of course (www.phpsurveyor.org)! --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-programming+help(a)opensuse.org

[opensuse-programming] Problem with large buffer on 10.2 when OK on 10.0 - solved!

by justin finnerty

Hello, Thanks for the help. We mainly run scientific code that is written by scientists rather than programmers and our machines are *usually* set up to be fairly forgiving of progamming style. "ulimit -s" shows that the stack size is limited to 8Mb on the 10.2 nodes and unlimited on the 10.0 nodes. Hence the program was crashing when it tried to allocate an 8Mb buffer on th 10.2 nodes. Now I just have to work out why the upgrade to 10.2 changed the limits. Cheers.

[opensuse-programming] Problem with large buffer on 10.2 when OK on 10.0

Hello, I am having problems running a program under Suse 10.2 that works on 10.0 when I increase the size of a buffer from 4MB to 8MB.
