 Posted: Sat Jun 08, 2002 3:25 pm Post subject: Seg faults |
 |
|
I am not knocking gentoo at all. I am running it on my home server as well as my desktop. But , I have noticed that on my desktop I get alot of seg faults. This has happend with some programs (Evolution) more then others. Is this becouse gentoo is on the cutting edge? Or is the other software just not mature yet? I am not going to stop useing gentoo but would like to know why this is happning and how to fix it.
I am running a tyan 2640 MB with dual amd (Not MPs) with 512 ddr ram and a nvidia geforce 3.

| sounds like your passing the wrong optimizations flags in your make.conf or something like that to me.. |

I have no idea for sure, but I would question the stability of dual non-MP Athlons/Durons (I realize that they work but that's not their purpose - that sort of thing can cause weirdness). Also, the other usual questions such as is your memory good and tested, what kind of optimizations did you use, etc. I would look to your hardware first. The fact that there aren't several hundred posts in these forums about everyone getting a lot of seg faults kinda lifts some of the blame off of Gentoo itself.  |

I would agree about shifting blame from gentoo. Like I said I love it!
this is what is in my make.conf
| Code: |
CHOST="i686-pc-linux-gnu"
CFLAGS="-march=i686 -O3 -pipe"
CXXFLAGS="-march=i686 -O3 -pipe
|
as for my ram it is good and tested as the box has been running about 8 mo (not with gentoo of course) now with noprobs at all exept for those that I mentioned.

| Evolution has some bugs, more so than many other programs. However, I would agree with the idea that you might be pushing your hardware too much, or that it's not playing nice with Linux, etc. Do you get segfaults if you disable SMP? |

that was one of the first thing I check. Being a MCSE (Don't stone me) I know that one of the first things you need to do is disable smp when you are having problams like this.

| Hmm... try compiling with -O2. -O3 is not very likely to break things, but it is still possible; -O2 breaks things even more rarely. |

Evolution depends on mozilla. Did you remove old versions of mozilla before emerging evolution? (emerge clean?)
Are you using athlon xp's with that board? I've read some reviews describing how smp systems using athlon xp's or even durons ran flawlessly even under heavy load. |
