how to install lpsolve library for MATLAB on Ubuntu 12.04 64bit?

I am trying to install this library for 3 hours.... first, for Python.. I gave up. Then for MATLAB...

http://web.mit.edu/lpsolve/doc/MATLAB.htm

I am still very confused, because the document barely says anything about how to install it.

Why is it so complicated? It is not like windows, in which for everything I want to install, double-clicking 'setup' or 'install' file on the .zip file installed everything I need.

I am so confused and distressed.. Please help me...

I do not know a bit about Ubuntu, so please explain to me which files I should download(there are a lot of files but I do not know what to download...), and how I could install it with what commands.

Thank you.

I am now trying to install this library in Matlab. But for python I got this solution some time ago:

-Installation guide for lpsolve with python -Linux Ubuntu 14.04

-Refference guide:

http://lpsolve.sourceforge.net/5.5/

-First install some lpsolve librarries:

sudo apt-get install lp-solve lp-solve-doc

sudo apt-get install liblpsolve55-dev

-Paste the following line command on ~/.bashrc and save:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/lp_solve/

-Open another terminal or execute on the current terminal:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/lp_solve/

-Downloading files:

-Go to the page:

https://sourceforge.net/projects/lpsolve/files/lpsolve/5.5.0.15/

-Download the file that contain the files for lpsolve:

lp_solve_5.5.0.15_source.tar.gz

-Extract the files to obtain the folder:

lp_solve_5.5

-Go to the page:

https://sourceforge.net/projects/lpsolve/files/lpsolve/5.5.2.5/

-Download the file that contain the extras files for python:

lp_solve_5.5.2.5_Python_source.tar.gz

-Extract the files to obtain another folder with the same name:

lp_solve_5.5

-Go to the second folder lp_solve_5.5 and copy the files inside ./extra/Python to the first folder lp_solve_5.5

-In the first folder lp_solve_5.5 open the file setup.py

-Change the line:

libraries = ["lpsolve55"]

-To:

libraries = ["/usr/lib/lp_solve/lpsolve55"])

-Now, still in the ffirst folder lp_solve_5.5 run: (maybe use sudo, I dont remember)

python setup.py install

-Now you should be able to run a example. In the first folder lp_solve_5.5 run:

python example1.py

-You should see:

78.26

31.7827586207

[28.6, 0.0, 0.0, 31.82758620689655]

[92.3, 6.864, 391.29282758620695]

I got the solution for installing lpsolve on Matlab. I tested it in Ubuntu 14.04.

First, go to the the following address:

https://sourceforge.net/projects/lpsolve/files/lpsolve/5.5.2.0/

Download the files:

1 - lp_solve_5.5.2.0_dev_ux64.tar.gz

2 - lp_solve_5.5.2.0_MATLAB_exe_ux64.tar.gz

3 - lp_solve_5.5.2.0_MATLAB_source.tar.gz

Extract all of the contents of these archives into a folder "lpsolve_matlab". Archives 1 and 2 will give a bunch of files, while archive 3 should give you a folder named lp_solve_5.5 Copy the file liblpsolve55.so, which is now inside lpsolve_matlab, to /usr/lib and /usr/lib64

sudo cp .../lpsolve_matlab/liblpsolve55.so /usr/lib

sudo cp .../lpsolve_matlab/liblpsolve55.so /usr/lib64

Note: 1) Replace ... by the path of your lpsolve_matlab folder. 2) You will need permission to do that, thus, you can also run 'sudo nautilus' to copy the files

Now, copy the files inside your folder lpsolve_matlab into the folder lpsolve_matlab/lp_solve_5.5/extra/MATLAB/lpsolve. Note that a some files are repeated, do not worry, you can replace them.

Open MATLAB, go to the folder lpsolve and run Makefile.m:

cd .../lpsolve_matlab/lp_solve_5.5/extra/MATLAB/lpsolve/

Makefile

You should see:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Automatic compilation of Matlab MEX interface for lp_solve 5.5

We assume that lp_solve 5.5 is installed in: ../../..

If that is not correct path for lp_solve 5.5, modify this file accordingly.

Press any key to continue

Then you press any key and you should see:

Compiling in progress. Please wait...

compiling...

Building with 'gcc'.

Warning: ...

Warning: ...

Compiling finished.

You can now run ex and lpdemo on matlab command line to test.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

You can also run the examples: example1.m, example2.m ...

This examples work because you are in the folder .../lpsolve_matlab/lp_solve_5.5/extra/MATLAB/lpsolve. If you want to add this folder permanently to matlab path type this in your matlab Command Window

addpath('.../lpsolve_matlab/lp_solve_5.5/extra/MATLAB/lpsolve')

savepath
