- Download the configure script.
- change directory to wherever the configure script has been downloaded to
- run the configue script by typing the command :


Note: if you get an error saying "permission denied", you need to change the mode of the file by typing:

chmod +x ./configure

Once the configure script has run successfully, you should have a new folder in your home directory called bpms. This folder contains the bin and src folders.

The script configure compiled the code in src/lib and should put the executable in bin/xxx where xxx is your machine architecture, similarly for src/lib for the libraries (.so files).

So to run it, you need to either have the binary directory (bin/xxx) in the PATH variable for your shell, or explicitly specify where the executable is (ie run it as /xxxx/yyy/bin/xxx/start).
It needs access to the shared object libraries, so you also need the directory that has the .so files in in your LD_LIBRARY_PATH. All of that is standard for running Unix codes.

To make changes to the environment variables, type in:

vi .bashrc

This opens an editor. You will now edit the .bashrc file, which is located in your home/username directory
To add the directories to the PATH and LD_LIBRARY_PATH variables, press "a" (without the quotes) to append the file, then type in the following commands:

export PATH=${PATH}:/home/usrnm/bpms/bin/xxx
export PATH=${PATH}:/home/usrnm/bpms/bin/csh
export LD_LIBRARY_PATH=${ LD_LIBRARY_PATH}:/home/usrnm/bpms/src/lib

where usrnm is your username and xxx is your machine architecture.
You can check your machine architecture using the following command:

uname -m

(This should return something like x86_64)
Once this is done, press esc to exit edit mode. Then type ":w" (without the quotes) to save the changes. Press ZZ to exit the editor.
Check that these directories have been added to your environment variables by typing in a new terminal:

echo $PATH

The new directories should be included in the environment variables. You should be able to run a command such as:

start < starttest.ip -sensor_wavebands wavebands.dat -m 100 -sun_position 0 0 10 test.obj

to test the start program.
