I can compile libcoin at my Ubuntu 11.10... I= just need to install:

sudo aptitude install libbo= ost1.46-all-dev

...alongside with another already = installed dependencies, and now it works!!

Thank you!

<= blockquote class=3D"gmail_quote" style=3D"margin:0 0 0 .8ex;border-left:1px= #ccc solid;padding-left:1ex"> Hi Martinx,

Another note:

boost 1.42 and openssl 1.0 has a conflict (you will see it when you try to = compile coinHTTP with that specific combination: sslv2 has been removed fro= m openssl, but boost still references it.)

You should do a :

sudo apt-get upgrade libboost-dev-all

to get the 1.46.1 library

/M
