Is there any solution? Thanks!

This is at least your second question with Makefile output in a different language. Please run LANG=C make instead of make to get English error messages. – Lekensteyn Feb 12 '12 at 18:41

The error is pretty obvious:

make[3]: flex: Command not found

Mesa has a build-dependency on flex which can be installed with:

sudo apt-get install flex

To install all build dependencies for Mesa at once, run:

sudo apt-get build-dep mesa

Thanks, the first command successed, but the second didn't. and after rebooting, videos in youtube seems to run slower, i think of installing ubuntu again ana ask her about the whole driver of my graphic card in my laptop – yinon Feb 13 '12 at 21:21
The second command just installs all build depenendecies which are only used when building (a.k.a. compiling) Mesa. It does not affect the Mesa version installed on the system. For a novice, I'd suggest not to mess around with mesa. Install the latest stable version to see if the issue sorts out (Oneiric 11.10 atm). – Lekensteyn Feb 13 '12 at 21:26
the second command, is i mean of the dri. i got involved with the driver for my intel graphic card – yinon Feb 14 '12 at 12:23
