Q :- I want to comile my code to convert into script file using mcc -m myfile.m but myfile.m is using external library (vl_feat) so I have included run('/vlfe​at/toolbox​/vl_setup.​m') , but when I try to run my script file , it is giving error ?

??? Error using ==> run at 65 /home/anirudh/vlfeat-0.9.16/toolbox/vl_setup.m not found.

Error in ==> searchImage at 7

Error using ==> run at 65 /home/anirudh/vlfeat-0.9.16/toolbox/vl_setup.m not found. MATLAB:run:FileNotFound

and vl_setup.m is there in vl_feat-0.9.16/toolbox/vl_setup.m only .

Any help regarding the above problem ?

Have you tried all the suggestions in the FAQ yet: http://matlab.wikia.com/wiki/FAQ#MATLAB_Compiler_Toolbox?

Where exactly is this "run" line? In your code, on the command line, somewhere else? Where did you put it?

When you say "run my script file" do you mean "run my compiled executable on the target computer" or "run my m-file script on my own computer"?

seventh line is run command only . Run line on the command line (matlab) just adds vlfeat library in the matlab path. It is in the code only . run(file) means run the file vl_setup.m

function [class] = searchImage(image,desc)

image='dataset/train/ans.jpg'

desc = 'sift'; run('/home/anirudh/vlfeat-0.9.16/toolbox/vl_setup.m'); %trainDir='dataset/train';

trainDir ='dataset/'; load(fullfile(trainDir,'images.mat')); load(fullfile(trainDir,'imageClass.mat')); load(fullfile(trainDir,[desc,'-invertedIndex.mat'])); load(fullfile(trainDir,[desc,'-vocab.mat'])); load(fullfile(trainDir,[desc,'-model.mat'])); load(fullfile(trainDir,[desc,'-hist.mat'])); im = imread(image);

Does vL_setup.m even run? If not, it's not finding it on the search path. Since you have just a relative path, it must be on the search path or else you have to put in the full path, not a relative path. I don't believe you can use addpath in compiled programs, so you either ship that file and install it in a known location, or else add that file to the mcc line with the -a option. It doesn't look like you took my suggestion to read the FAQ, or didn't understand it.

Sir,

mcc -m searchImage.m -a /home/anirudh/vlfeat-0.9.16/toolbox/vl_setup.m

I have compiled using this also as suugested by you and given in the Faq's But still it is giving error .

./run_searchImage.sh /usr/local/MATLAB/R2010b/

Try including the run command in the startup file in Matlab. This will run the VL_setup every time matlab is initialised.
