wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py
sudo python3 get-pip.py

2. Download and install pre-build debian packages of libsodium for Unbuntu

5. Install cutecoin repository

git clone https://github.com/ucoin-io/cutecoin

or download from this link

https://github.com/ucoin-io/cutecoin/archive/master.zip

export PYTHONPATH=${PYTHONPATH}:/cutecoin_install_path/src:/cutecoin_install_path/lib

7. Run cutecoin main script

python3 src/cutecoin/main.py

Install cx_freeze to build your own binaries

Install python3 dependencies

sudo apt-get install python3-dev
sudo apt-get install libssl-dev

Install cx_freeze source

mkdir cx-freeze; cd cx-freeze; apt-get source cx-freeze

Build and installā€¦

python3 setup.py build
sudo python3 setup.py install

The installed command is cxfreeze

If a problem occur during the build, edit setup.py and change the line

    if not vars.get("Py_ENABLE_SHARED", 0):

to

   If True:

You can create yourself libsodium debian packages on ubuntu :

Install tools to create a debian package

sudo apt-get install devscripts debhelper build-essential

Create a script file to build the package :

#!/bin/bash
#Revision 1
#Libsodium DEB build script. Call without arguments.

export NAME=libsodium
export VERSION=1.0.1
export DEBVERSION=${VERSION}-1
#Download and extract the archive
if [ ! -f ${NAME}_${VERSION}.orig.tar.gz ]
then
    wget "https://download.libsodium.org/libsodium/releases/${NAME}-${VERSION}.tar.gz" -O ${NAME}_${VERSION}.orig.tar.gz
fi
tar xzvf ${NAME}_${VERSION}.orig.tar.gz
cd ${NAME}-${VERSION}
rm -rf debian
mkdir -p debian
#Use the existing COPYING file
cp COPYING debian/copyright
#Create the changelog (no messages - dummy)
dch --create -v $DEBVERSION --package ${NAME} ""
#Create copyright file
cp COPYING debian/copyright

This changed in cutecoin 0.5, we now use libnacl and libpyscrypt. But it still uses libsodium so this is still useful :wink:

I reached step:

sudo pip3 install pynacl

I encoutered a first error since I had not pip3 installed. So I ran:

sudo apt-get install python3-setuptools
sudo easy_install3 pip

then ran:

sudo pip3 install pynacl

and encountered following error:

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-94il_7xr/pynacl

Have you an idea of what happens? (Iā€™ve nothing in the error file)

4

pynacl builds libsodium via cffi during ā€œpip installā€.

You should try with libnacl, it should be easierā€¦

pip install libnacl

ā€¦

from libnacl.sign import Signer
5

It seems ok with this @Inso, thanks!

6

I had to install package libffi-dev as well before I could install pynacl.

7

Once again it is not needed anymore. We use libnacl. I guess vit should edit his post ^^

8

Install procedure has been updated for version 0.5+
Should work nowā€¦

9

Cutecoin 0.7.5 will need python-requests 2.5.1+ and the ubuntu default version is only 2.2.1ā€¦

So I updated the installation procedure to install requests with pip3 and get the latest version.

If requests is already installed, just upgrade it like this :

sudo pip3 install requests --upgrade
10

The tuto of installation of uCoin/Cutecoin whould be better updated in a Wiki better than adding comments at the end of a forumā€¦

11

E: Impossible de trouver le paquet sodium
???

12

Its an error. Go directly to step 2.

13

Post fixed and updated with more complete instructionsā€¦ :smile:

14

Could you also add the explanation about how to install cx_freeze on ubuntu ?

( http://stackoverflow.com/questions/19873673/error-when-compiling-cx-freeze-on-ubuntu )

15

Done.

I did not have to edit the setup.py file to get it build !
I did not use cxfreeze for nowā€¦

16

On my ubuntu installations it didnā€™t work, I had to edit the file. Are you sure you built cx-freeze for python3? :o

Maybe they fixed their python3 packageā€¦

Hello, trying this installation, and Iā€™m stuck at 6.
I extracted the folder in my personnal folder, and indicated that path in the commad :

export PYTHONPATH="${PYTHONPATH}:/home/famille/cutecoin-master/src:/home/famille/cutecoin-master/lib"

but when I write :

$ python3 src/cutecoin/main.py
python3: canā€™t open file ā€˜src/cutecoin/main.pyā€™: [Errno 2] No such file or directory

So I put the real path in 7.

$ python /home/famille/cutecoin-master/src/cutecoin/main.py

And I get

File "/home/famille/cutecoin-master/src/cutecoin/main.py", line 2
SyntaxError: Non-ASCII character '\xc3' in file /home/famille/cutecoin-master/src/cutecoin/main.py on line 3, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

What is wrong with my path ?
Does anyone know something abour an ASCII issue and how to work around it ?

Thank for your help, and sorry for being a real newb !

@Guyver, the more easy way to install CuteCoin for users is described here :

https://github.com/ucoin-io/cutecoin/wiki

You should do the very easy installation for users, then read the tutorial ā€œgetting startedā€ā€¦

For your problem, try this :

cd  /home/famille/cutecoin-master
python3 src/cutecoin/main.py
20

Thanks, got it ! Iā€™ll go for the simple user version.

But when I execute cutecoin in the file, nothing happens ā€¦ :frowning:

I do have libsodium13 installed, though.

Any clue ?
