MQL5 ALGLIB : fatal compiler error : code generation failed

ndnz2018 · **Joined:** Mon Feb 26, 2024 2:44 pm **Posts:** 2

Hello,

i get the following error with the last alglib update (2023.09.08 17:34). It's caused by function MNLTrainH.

fatal compiler error: code generation failed

Here the minimal example to reproduce it:

Code:

#include <math\alglib\alglib.mqh>
CLogitModelShell log_mod;
CMNLReportShell log_mod_rep;
CMatrixDouble log_mod_data;
int log_mod_info = 0;
void OnStart()
  {
      CAlglib::MNLTrainH(log_mod_data, 10, 3, 2, log_mod_info, log_mod, log_mod_rep);   
  }

I hope somebody can help.

Greetings

cn

Hi! The MQL5 port is an unofficial port by MQL developers, it is not supported by ALGLIB Project. Actually, I do not even know MQL language :) so, it is impossible to get a support here.

Hello,

i have isolated the code line. The following line 14559 in dataanalysis.mqh is wrong, but i don't know why ?

Code:

//--- evaluate the function and gradient at stp
//--- and compute the directional derivative.
x=wa+s*stp+0;
