Cannot find bufffer.c

[alphaville]

I have added to my MATLAB path the folder src in nmpc-codegen-matlab. I then cd to nmpc-codegen-matlab and run the demo script TwoCircTrailer which gives me the following error

Error using copyfile
cp: cannot stat ‘/home/chung/Documents/NMPCCodegen/old_code/PANOC/buffer.c’: No such file or directory

Error in nmpccodegen.tools.Bootstrapper/copy_over_file (line 148)
                copyfile(src_location, dst_location, 'f');

Error in nmpccodegen.tools.Bootstrapper/generate_PANOC_lib (line 69)
                nmpccodegen.tools.Bootstrapper.copy_over_file(src_location,dst_location,overwrite);

            nmpccodegen.tools.Bootstrapper.generate_PANOC_lib(output_location_controller,location_nmpc_repo,overwrite)

Error in prepare_demo_trailer (line 8)
    nmpccodegen.tools.Bootstrapper.bootstrap(trailer_controller_output_location, true);

Error in TwoCircTrailer (line 16)
trailer_controller = prepare_demo_trailer(controller_folder_name,step_size,Q,R,Q_terminal,R_terminal);

I see that the third line in this file is

addpath(genpath('../../src_matlab'));

The use of relative paths is not very reliable. I guess I need to add nmpc-codegen/old_code/src_matlab to the path. I did that manually, but this didn't solve the issue.

I see, however, that it looks for buffer.c at /home/chung/Documents/NMPCCodegen/old_code/PANOC/buffer.c, while the correct path should be /home/chung/Documents/NMPCCodegen/PANOC/buffer.c.

Sloppy solution: I changed line 44 in Bootstrap.m to location_repo = [Folder '/..'] ; and it works.

It gives me a different error now, but I'll report it in another issue.

yea your right, i used relative path here for ease of use for the user, maybe i should use the one already in the path and display an error to the user that he should add the lib to the path
