Hi Michael!

 I just run "bitcoind", from libcoin ("sudo make install") sources, with
empty ~/.bitcoin directory and:

Terminal 1: bitcoind # apparently okay

Terminal 2:

$ bitcoind getinfo # okay
{
    "version" : 40001,
    "blocks" : 57733,
    "connections" : 8,
    "difficulty" : 11.84622815,
    "testnet" : false
}

# sleep a couple minutes

$ bitcoind getinfo # ok
{
    "version" : 40001,
    "blocks" : 67527,
    "connections" : 8,
    "difficulty" : 45.38582234,
    "testnet" : false
}


But...


$ bitcoind help
HTTP error code: 404
JSON RPC Error code: -36001
Method not found.

$ bitcoind getaccountaddress ""
HTTP error code: 401
Error: couldn't parse reply from server

$ bitcoind listaccounts
HTTP error code: 401
Error: couldn't parse reply from server


 Any tips?! lol

Thanks!
Thiago

Hi Martinx,<br>
<br>
Another note:<br>
<br>
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.)<br>
<br>
You should do a :<br>
<br>
sudo apt-get upgrade libboost-dev-all<br>
<br>
to get the 1.46.1 library<br>

&gt; =C2=A0Anyway, I am unable to compile libcoin under my Ubuntu 11.04. At=
 this machine, I have compiled and running Bitcoin (from sources), Namecoin=
, Devcoin, Litecoin, IXcoin and I0coin, all from sources but, when I try to=
 compile libcoin, I got:<br>

&gt; Dear Bitcoiners,<br>
&gt;<br>
&gt; libcoin is now in a state ready for its first release, which I would l=
ike to share with you!<br>
&gt;<br>
&gt; =3D=3D=3D libcoin is a crypto currency library based on the bitcoin/bi=
tcoin &quot;Satoshi&quot; client. =3D=3D=3D<br>
&gt;<br>
&gt; Copenhagen, Denmark - 1st February 2012 Ceptacle announces the release=
 of the first version of the crypto currency library &quot;libcoin&quot; ba=
sed on the bitcoin/bitcoin &quot;Satoshi&quot; client.<br>
&gt;<br>
&gt; libcoin also maintains a version of bitcoind that is a 100% compatible=
 drop-in replacement of the bitcoin/bitcoind client: You can use it on the =
same computer on the same files and you can call it with the same scripts. =
And you can easily extend it without touching the basic bitcoin source file=
s.<br>



&gt;<br>
&gt; The libcoin/bitcoind client downloads the entire block chain 3.5 times=
 faster than the bitcoin/bitcoind client. This is less than 90 minutes on a=
 modern laptop!<br>
&gt;<br>
&gt; In libcoin, the Satoshi client code has been completely refactored, pr=
operly encapsulating classes, removing all globals, moving from threads and=
 mutexes to a pure asynchronous approach. Functionalities have been divided=
 into logical units and libraries, minimizing dependencies for e.g. thin cl=
ients.<br>



&gt;<br>
&gt; libcoin is chain agnostic, all chain (bitcoin, testnet, namecoin, lite=
coin, ...) specific settings are maintained from a single class (Chain) and=
 hence experiments with chain settings, mining, security and digital curren=
cies for research and educational purposes are easily accessible. See the p=
onzicoin example for how you define your own chain.<br>



&gt;<br>
&gt; The build system of libcoin is based on CMake and supports builds of s=
tatic and dynamic libraries on Linux, Mac OS X, and Windows.<br>
&gt;<br>
&gt; The libcoin license is LGPL v. 3. This mean that you can use it in ope=
n source as well as in commercial projects, but improvements should go back=
 into the libcoin library.<br>
