[mesa-users] Installing MESA in Ubuntu (9.10, 10.04 and 12.04) and Fedora Core 8 without root privileges

[Max Katz]

Alessandro,

Thanks for putting this together. I haven't had to install mesa without
root privileges yet, but I can confirm that every step other than the
LD_LIBRARY_PATH environment variable is all you need for installing it on
Ubuntu *with* root privileges. I do want to point out one minor thing that
occurs if you're using a 32 bit installation of Ubuntu -- step 3 refers to
a slightly different set of directories:

cp -rf /usr/include/i386-linux-gnu/*
/your_path_to_mesasdk/lib/gcc/i686-pc-linux-gnu/4.7.0/include-fixed/

This was originally pointed out to me in an earlier set of e-mails
regarding MESA on Ubuntu on this mailing list by M. N. Anandaram.
