NF fails to evaluate Integer in if expression

[ulrich1a]

The following model runs fine in OF but fails in NF:

model evalTest 
Real[2] a;
protected
parameter Integer X(fixed=false) "fails in equation evaluation";
initial algorithm
X:= 1;
equation
  for i in 1:2 loop
    if X==i then
      a[i] = 2;
    else
      a[i] = 3;
    end if;
  end for;
end evalTest;

The error message is: Interner Fehler NFCeval.evalRelationEqual failed to evaluate ‘X == 1‘

Such errors should have been fixed several months ago, and I can't reproduce the issue. Which version of OM are you using?

[ulrich1a <ubrammer@…>]

I am using the following version:
OMEdit v1.14.0-dev.62+g21f82a33
Connected to OMCompiler v1.14.0-dev.269+g5dc61f678
Connected to OMSimulator v2.1.0-dev-148-gd6918bd-linux

I am getting the error with the Additional Translation Flags: -d=initialization -d=aliasConflicts +std=3.3 -d=newInst

I did compile OpenModelica on Debian Stretch a few days ago after pulling the latest commits.

I may have to add, that it is required to finish OMEdit after setting the flag -d=newInst and start OMEdit again. Otherwise the flag has no effect.

I confirm that the problem is resolved if using the latest nightly build.

The version of OMCompiler that you are using dates back to 15 May, and it refers to the repository ​OpenModelica/OMCompiler which is now obsolete. Starting from mid-may, the OpenModelica source codes, that were previously stored in separate sub-projects, where brought under the ​OpenModelica/OpenModelica repository.

If you are compiling from sources, please make sure that you are using the ​latest commit. Otherwise, you can try the latest nightly build.
