Hi,
I'm using Gauss 10 and have this error
Undefined symbols:
log_lik
of this line of my code
{ML_coef,f,g,ret}=CO(&log_lik,ML_coef);
I also tried modifying it to &loglik but it didn't work, also I have loaded library co.
Could you please help fix this?

The first input to the CO procedure is a pointer to a user written procedure. You need to write a procedure to calculate the log-likelihood. You can name it whatever you like. It does not have to be named log_lik, or loglik or anything in particular.
Most commonly, the log-likelihood procedure is defined inside of the same file that contains the call to CO. If the log-likelihood procedure is defined in the same file, it should be found unless you have the "Auto delete" preference setting turned off. (Tools->Preferences->Advanced in GAUSS 15).
Alternatively, GAUSS will be able to find your procedure if it is included in a GAUSS library and that GAUSS library has been loaded or if you place the procedure in a file with the same name as the procedure in a file with a .g extension in your GAUSS working directory.
