undefined symbol


I am running a piece of code written by someone else, and I get many errors.

Here are the errors:

G0025 : Undefined symbol: 'read_file' [3 recup_girf-orig.prg, line 23]

G0025 : Undefined symbol: 'calcule_stat' [3 recup_girf-orig.prg, line 24]

which are related to these two lines of the code:

loulou1 = read_file(name,_nvar_*_nbchoc*AA*BB,j) ;
temp = calcule_stat(loulou1,lag_max,j,"") ;

so I don't understand whether read_file and calcule_stat  are commands which I can't run because I maybe do not have libraries related to them or I am missing something else.

your help is so much appreciated. thanks!

Based on your report, read_file and calcule_stat are GAUSS procedures which have not yet been defined. I do not recognize them as part of any official GAUSS package. Most likely they are some user-created GAUSS procedures.

This could be because:

  1. The procedures are part of a library created by the author of the code.
  2. The procedures are in another file and that needs to be run or #included.
  3. The procedures are in the file you are running, but you ran the code line-by-line, but you need to run the entire file at once.
