invalid argument in select() when peer socket is in FD_SET
I have written a small to test TCP/IP roundtrip times of the packets in
a proprietary protocol and while
compiling and running this server on different platforms (Windows
7/cygwin, UbuntuLinux, FreeBSD 8.0 Release), I found
that the server produces an error when the listening socket (on which
the accpet() is performed) is member of the select()
fd_set.
On the other platforms the program works without error, just under
FreeBSD I'm getting this invalid argument error.
Comments appreciated (despite comments about the error checking logic :)

Phenom II 975 BE shows 0 celsius
Hi to all In my desktop machine, I had an AM2+ ASROCK mobo with Phenom II 955 BE that showed each core temperature perfectly under FBSD 8-STABLE, via dev.cpu.x.temp. amdtemp.ko loaded. Unfortunately this Mobo died and only found AM3 boards for which my phenom 955 doesn't fit. So I got an ASUS M4A88T-V EVO with a Phenom II 975 BE. Funny thing. An AM3 phenom II fits on an AM2 board but an AM3 board doesn't accept an AM2/AM2+ phenom II :(. Anyway, now, under the very same system, it shows 0 degrees on dev.cpu.x.temp for all cores. I've been looking through k8temp and amdtemp src code. I am definitely not sure of this but I believe something might have happened to those: From k8temp.h K10_THERM_REG 0xa4 K10_THERMTRIP_REG 0xe4 K10_CURTMP(val)(((val) 21) 0xfff) K10_THERMTRIP(val) ((val 1) 1) From amdtemp.c /* * Register control (K8 family) */ #define AMDTEMP_REG0F 0xe4 #define AMDTEMP_REG_SELSENSOR 0x40 #define AMDTEMP_REG_SELCORE 0x04 /* * Register control (K10 K11) family */ #define AMDTEMP_REG 0xa4 Output of k8temp -dn: CPUID: Vendor: AuthenticAMD, 0x100f43: Model=04 Family=f+1 Stepping=3 Advanced Power Management=0x1f9 Temperature sensor: Yes Frequency ID control: No Voltage ID control: No THERMTRIP support: Yes HW Thermal control: Yes SW Thermal control: Yes 100MHz multipliers: Yes HW P-State control: Yes TSC Invariant: Yes Temp=c0fef ThermTrip=1fc00c30 0 I keep a small win7 partition to test little things like this and see if the same thing happens there, and it doesn't, so I concluded that the sensors are there and are working. One thing is worth noting though. I have used a free gadget that shows activity/temp for each core. It worked fine with the previous MB/CPU.That ALSO stopped working with this new MB. Like FBSD, it shows 0 degrees for any core too, although it correctly displays each core load. The only windows tool that correctly shows the temperature are the ASUS tools that came with the mobo. Other than that, everything is working fine! The only thing I had to fix was the fstab ada location. I know this is not a big thing but I got accustomed to keeping an eye on those temperatures. I have googled for a few days now searching for Thermal register address or offsets for the Phenom II 975 BE, or anything related to this problem and found nothing. Every search on AMD site was fruitless. I could not find a single bit of tech info on this processor there, or any other tech info for that matter. Would any one have any pointers/clues/suggestions on this?

Re: can't build teTeX port in FreeBSD 8.2 amd64
If you are using TeXLive, first check if a TeXLive package for what you want exists. First tell tlmgr(1) to use a CTAN mirror: tlmgr option repository http://mirror.ctan.org/systems/texlive/tlnet Then list all packages available: tlmgr list|less The packages you have installed are prefixed with an 'i'. Am taking a look at TDS, but still confused :( Make a texmf directory in your $HOME. This is searched by default in TeXLive. See /usr/local/texlive/YEAR/texmf/web2c/texmf.cnf Just unzip pgfCVS2010-09-28_TDS.zip in ~/texmf, and run mktexlsr afterwards. Roland -- Roland, I was finally able to compile this one with tikz stuff :) but with texlive2010 not with teTeX from ports(yet). Followed your suggestions, except that I did a global install of pgf file in /usr/local/texlive/2010/texmf/ folder, copied pgf zip file there and unzipped it, ran mktexlsr as root and finally had to snatch picnic.sty http://www.ctan.org/tex-archive/macros/latex209/contrib/picins then it worked. I might have to try something similar with the teTeX system but it looks more complicated, there are more files and where should I place them so that everything falls into place? Anyhow, thanks for the suggestions.

Re: can't build teTeX port in FreeBSD 8.2 amd64
http://pastebin.com/23RCus2a http://tobi.oetiker.ch/lshort/lshort-5.01.src.tar.gz ran gmake and I see the errors. One error is that in src/ folder, the file lshort-letter.tex does not exist :(, if we cd to that folder and copy the lshort-a5.tex lshort-letter.tex then it will build provided most of the other files(sty) are found and no error occurs. That is one solution, the other could be editing the Makefile (to not build the lshort-letter.pdf). This lshort was able to build with the fix but on TeXLive not yet with teTeX :(, will see which files I need first then get back to compiling it fully and hopefully I can succeed as well.
