First, did you following the instruction on this page: http://flightgear.org/Docs/InstallGuide/ge...tml#x6-160002.4? Next, which distribution of Linux are you using? Thirdly, which command gave you that output? I presume it is ./configure of something (what is that something)?

No, I did not following the instruction from that page because I use Gentoo. So I did this:# emerge flightgearHowever building libraries was successful. But I checked my system. Plib and simgear are already installed.Thank you.

If you need more help, you will have to ask it on the mailing list. You can subscribe for the user mailing list by going to www.flightgear.org/mail.
