GCC Using command

gcc is a GNU project compiler, and you can see it on many Unix like system.

I'll note some using way.

#gcc -O foo.c -o bar.out
#./bar.out

Compile a C program file to a execution file.

-O -> Optimization parameter

-O3 -O2 -O1 -O0    -> 0 do not optimize, 3 is best optimization.


#gcc -Wall -g foo.c -o bar.out

-Wall  -> displayed the warning message  
-g  -> Using gdb debugging and show error message

#gcc -I/usr/include -L/usr/lib -lm test.c -o test 

-Idir_name -> find the header file in directory

-Ldir_name -> find the linrary file in directory

-llibfile_name -> join a library file "libm.so" overpass lib & .so

OSX snowleopard server mailserver Clamav issue

when I used the serveradmin to watch the System log.

I saw the error message log :

Apr 28 00:30:07 macminiserver com.apple.launchd[1] (org.clamav.clamd): Throttling respawn: Will start in 10 seconds

then I restart my clamav freshclam and update clamav

#sudo launchctl unload -w /System/Library/LaunchDaemons/org.clamav.freshclam.plist

#sudo launchctl load -w /System/Library/LaunchDaemons/org.clamav.freshclam.plist

after this command, we can check the log in the serveradmin and it will start to update the virus database. And the error log does not appear again.

MAC OSX cpuinfo flags command

SHOW you CPU info like Linux command #cat /proc/cpuinfo | grep flags

#sysctl -a machdep.cpu | grep VMX

Synergy KVM software control on MAC OSX & UNIX by MacBook Air to Mac Mini Server

download & convert file => Synergy Download

you will find synergy-x.x.x-MacOSX-Universal folder

Server (MacBook Air keyboard & touchpad)

open and cp doc/synergy.conf.sample synergy.conf

vi the conf file like this


section: screens
        foo.local:
        bar.local:
end


section: links
        foo.local:
                right = bar.local


        bar.local:
                left  = foo.local
end

execute the synergy server by configure and listen client connection

#sudo ./synergys -f --config synergy.conf




Client (Mac Mini Server + screen)


#./synergyc -f "HostName or IP"




The result is that can use Air's keyboard and touchpad to remote control the 


Mini Server screen and key-in.


And I have more efficiencies to do my job by the one keyboard and touchpad with two Macs.
