libosmocore

libosmocore is a library with various utility functions that were originally developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.

There is no clear scope of it. We simply move all shared code between OsmocomBB and OpenBSC in this library to avoid code duplication.

To build osmocom-bb it is mandatory to install libosmocom in advance.

To compile libosmocore you will need the following tools:

So open up a terminal window and execute the following commands:

sudo apt-get install build-essential libtool shtool autoconf automake git-core pkg-config make gcc

like shown here

and press Enter

u should then see this

Cause i already followed the Getting Started Guide it’s already installed here.

You should also start with the Getting Started Guide

Otherwise type Y and press Enter again.

next u need to install the following libraries:

sudo apt-get install libpcsclite-dev

so paste this in the terminal like shown here

And press Enter

u should then see this

Obtaining it

To obtain libosmocore, you can use the following git URL:

git clone git://git.osmocom.org/libosmocore.git

So open up a Terminal window and paste it

like shown here

and then press Enter

u should then see this happening

Compiling and installing it

To compile and install it as standalone:

In the same Terminal window now type:

cd libosmocore/

and press Enter

next u should be here

now that u are in this folder u should type the following command

autoreconf -i

and press Enter

u should then see this

after that’s done u should type the following command

./configure

and press Enter

u should then get this

This is the first error u get, but no worries i am going to tell you how to fix this

Since it’s saying No package ‘talloc’ found

we are going to install it manually

So first we are going to install a package manager called Synaptic

so let the existing terminal window open with the error and open up a new terminal window

you install the package manager by entering the following command:

sudo apt-get install synaptic

Now press Enter

and you should see this

So now type Y and press Enter again

u should after u pressed Enter you see this happening

So now the package manager called Synaptic is installed

To open it u should type the following command in the Terminal window:

sudo synaptic

and press Enter

u should then see this

in the Quick introduction window u can click close

and should then see this

Now this is the Synaptic Package manager

u should now click in the top right corner on Search

once u clicked on Search u should see the following search box

since we got the error No package ‘talloc’ found during the ./configure command for libosmocore we need to search talloc here

so in the search box type talloc

like shown here

and now press the Search button

u should then see the following

now right click on libtalloc-dev and select Mark for installation

you should now see a marker in front off libtalloc-dev

like seen here

next click on Apply in the Top bar

after u clicked Apply this window should come up

This is ok so click Apply again

u should then see this happening

and when done this

u can Click the Close button

now that this is closed u get back on the main window

now that you are here again close the Synaptic package manager in the top right corner

like seen here

now that u clicked close u should see this.

this is the terminal window where u launched the synaptic package manager

you can close that for now

to do so you type

exit

Like shown here

and press Enter

You should now come back to this terminal window if u let it open at least.

(otherwise go back to the libosmocore folder in the terminal window with the command cd libosmocore )

so since the ./configure command went wrong because of the talloc package it should run fine now

so re-type

./configure

or press the up arrow to load the last command

like seen here

So now that u have typed ./configure again press Enter

and u should see this passing by

and this when it’s doneNow that this is done we can run the next command in the same Terminal window

the command u should enter now is :

make

and press Enter

u should then see this passing by

and this when the make command is done

the next command we are going to run is:

sudo make install

after u type this command u can press Enter

and should see this passing by

and this when it’s done

now that this is done we can go on to the next command

the next command you need to type is:

sudo ldconfig -i

when you entered this command u can press Enter

nothing is going to display but u should come out back here again

Congratulations

You are now done with compiling and building libosmocore
