I'm having the same problem with atof()! I've been going nuts tring to find the cause! Is it a library bug, or what? Linux 1.0.8, libc.so.4.5.24, gcc 2.5.8, 486DX40.

But config.h has a line in it that #includes "", and there is no autoconf.h anywhere on my system. So far I've been able to get around the problem by commenting the #include of that file out of config.h, and the applications seem to build without problem... but it makes me uncomfortable when I have to hack system files like this... Is this #include of autoconf.h an error in config.h, or should I really have an autoconf.h? BTW, I am currently running 1.51, which started as a complete 1.45 with the subsequent patches applied in sequence. -- Michael Nelson nelson@seahunt.imat.com San Francisco, CA FAX: 1-415-621-2608 ------------------------------ Crossposted-To: comp.os.linux.help,comp.os.linux,alt.uu.comp.os.linux.questions From: huw@isgtec.com (Huw Leonard) Subject: Re: Linux & Netware.

If you mean, can I talk to the Linux machine with Netware, the answer is: if you have TCP/IP bound to one of the NICs on your server, yes! I've run IBM's TCP/IP over Token Ring with OS/2, but never with Netware. The Netware support for Unix resources (esp. printers) is pretty good, by many accounts. I don't see any reason why Netware should have any problem with Linux, if both are configured properly. ============================================================ Huw Leonard - Speaking only for himself ------------------------------ From: mah@ka4ybr.com (Mark A.

Well, I really am not trying an BSD vs. Linux argument, just want to give you some data points on NCR performance. (Anybody got BONNIE results for other controllers on a similar hardware platform (ie. modern 1GB drive and 486/66). ???) The following are BONNIE results from our NCR 53c810 driver run on a 486DX2/66 under FreeBSD-1.1.

I've marked the most interesting values: Reading 8KB blocks (what that file system release generally does) is 1.7MB/s and takes 17% of the CPU. Writing is up to 3.0MB/s at 40% of the CPU, since finding free blocks takes more cycles than just reading the indirect blocks ... Using TAGS helps a lot with this drive, which doesn't seem to do any read ahead on its own ... More then 8 TAGS reduce throughput, so 4 to 8 seems to be most reasonable. These values compare favourably against those obtained on large RISC file servers. -- Stefan Esser Internet: Zentrum fuer Paralleles Rechnen Tel: +49 221 4706010 Universitaet zu Koeln FAX: +49 221 4705160 Weyertal 80 50931 Koeln ------------------------------ From: jjfox@anshar.shadow.net (Jay Fuchs) Crossposted-To: comp.sys.next.advocacy Subject: Re: OpenStep on GNU or Linux?
