MATLAB Central Newsreader - can't fopen????

can't fopen????

liu I-YIN — Tue, 22 Jul 2008 03:00:06 -0400

hi all,
I used matlab 14.4 to transfer M-file to c code.
The original M-file is
fid = fopen('tx_para.txt','r')  It works
But after it transfer to c code, it shows error:
??? Undefined function or method 'deploywhich' for input
argument of type 'char'.
Error in = = > fopen at 16
Error in = = > get_tdv_params at 230
Error in = = > tdv at 61
Error in = = > top at 12

Due to matlab 14.4, I can not export every M-file to C-
file by one-one mapping. I can only export the top.m,
which means I can not really “see” the get_tdv_params
after transfer /_\
How should I do?

I'm not sure what you mean by that. Do you mean that you
used the Matlab Compiler ? If so, then which release of the Matlab
Compiler?

Please use

which fopen

to be sure that you are getting the built-in fopen and not
a user-defined function that happens to be named fopen.
fopen line 16 is normally a comment line, part of the 'help' description
of fopen.

  I change it to matlab 2006b, glibc 2.3.3.
  but it still doesn't work.
  the way I transfre the M-file is like
  mcc -I /code
      -I /matlab/2006b/toolbox
      -I /matlab/2006b/extern/include
      -W lib:libmatlab -T link:lib /code/top.m
      -f my_mbuildopt.sh
