Hi, I want to investigate the tools' performance. And I have downloaded the source code from the website. But I fall into trouble now. Because those tools provide a simple way to the compile and install , just like ./configure make make install So I want to add parameter "-pg" during the compiling, but I have no idea with it. Would someone kindly do me a favor ? Any help is appreciated. ----------------------------------------------------------------- < ¨C¤Ñ³£ Yahoo!©_¼¯ > www.yahoo.com.tw
