Chromium touchscreen scrolling.

That's a nifty extension: a trick to make WeTab browsing a real experience. Install this to have an iPad like, single-finger scroll in Chromium. On the right of the adress bar you can choose from auto (scroll when touch in page, but not in letters), full (scroll wherever you touch), or turn it of (so you can select that url).

GLIBCXX_3.4 not found problem in Matlab under Ubuntu

Today wanting to experiment with compilation tools in Matlab R2010b under Ubuntu 11.04 I faced the following error using the latest gcc 4.5 to compile the example 'yprime.c' given in Matlab's mex guide:

$matlab/sys/os/glnx86/libstdc++.so.6: version `GLIBCXX_3.4.sth not found 

Searching in Google revealed that I haven't installed g++ libraries. Straight to synaptic package manager to install libstdc++ (I also installed g++, gcc-multilib and c++ just to be sure :p). But the problem was still there..

After a little digging I found a post describing that i had to replace some files in /usr/local/matlabfolder/sys/os/glnx86/ folder. Had to remove matlab's libstdc++.so files:

cd /usr/local/matlabR2010b/sys/os/glnx86/

Create backup of the three files first!!

sudo cp libstdc++.so.6 ~/Desktop
sudo cp libstdc+.so.6.0.14 ~/Desktop
sudo cp libgcc_s.so.1 ~/Desktop

then get rid of the old ones:

sudo rm libstdc++.so.6
sudo rm libstdc+.so.6.0.14
sudo rm libgcc_s.so.1

and substitude them with the ones used by gcc (probably in /usr/lib/i386-linux-gnu/ or just /usr/lib/)

sudo ln -s /usr/lib/i386-linux-gnu/libstdc++.so.6
sudo ln -s /usr/lib/i386-linux-gnu/libstdc++.so.6.0.14
sudo ln -s /usr/lib/i386-linux-gnu/libgcc_s.so.1

and presto, Matlab compiles like charm!
