You do not have write permission in the output directory:
  '/home/bamidele/matlab/bin'.
??? Error using ==> mcc
Error executing mcc, return status = 1 (0x1).

Are you running this command from inside a MATLAB directory (ie. where MATLAB is installed)? Try from a different location, such as your home directory.

[Jerry Gregoire]

I had a similar problem. Your ans was simple and spot on. I hadn't noticed that ML booted to my \program files\... \matlab folder.Thx

Why does the run location matter? This shouldn't be an issue so long as all the pathing parameters are absolute.

[Walter Roberson]

However, the user's paths were not absolute, they were relative, and they did not specify an output directory. The current directory was used, but the user's current directory could not be written to.

It is also possible that temporary or partial files needed to be created. The de facto standard for toolchains is that when partial results are to be created, that they are created relative to the current directory unless the command line directs otherwise. This arrangement allows for edit / compile cycles where errors might appear in one or more files, and it would be inefficient to require that all of the files be reprocessed.

[Christopher]

Ah, I see the lack of absolute pathing now. I missed that the first time around.

I'd disagree that the de factor for temporary files would be the working directory though. The de facto for temporary file locations should be the temporary directory of your system (i.e. %TEMP% or /tmp/).

hi,

i installed matlab to /home/me/matlab

when i load matlab it goes to this directory.

i have cd to /home/me/workspace instead and run the mcc command with the same issue.

[ade bamidele]

problem was solved with sudo chown -R ${USER}:${USER} ~/.matlab

[Dekang]

could you please provide more details? I have tried sudo and it says undefined function.
