Error in mkoctfile

I am trying compile he following in octave4.0 in Linux 14.04 :

mex CFLAGS="\$CFLAGS -std=c99" -largeArrayDims read_data.cpp

mex CFLAGS="\$CFLAGS -std=c99" -largeArrayDims write_data.cpp

The following error crops up :

****mkoctfile: unrecognized argument CFLAGS=-std=c99**

**warning: mkoctfile exited with failure status****

Anyone knows what this means and how to fix this?

You should run a setenv('CFLAGS','-std=c99 -whatever -else') command (inside octave) like, for instance:

setenv('CFLAGS','-std=c99');
mkoctfile --mex file.c

But perhaps you want to add the CFLAGS you already have. Well, I know no elegant way to do this, so I would do it manually with a 

mkoctfile -p CFLAGS

And copy-paste the result together with your '-std-c99' option, or set it up in the shell before entering octave with a 

~$ CFLAGS=$CFLAGS:"-std-c99" octave
