I am trying to install FIX. I made some changes in settings.sh and I installed R. (I have MATLAB with signal toolbox, I didn't install Octave.) Then, I ran './build_MATLAB' in fix1.06 folder, however, error message appeared like below. Invalid directory: /Users/myname/fix1.06/-d/ make: *** [fix_3_clean] Error 1 I do not know what the problem is and how to deal with. Also, how can I know whether FIX is installed successfully or not? Thank you for your help.
