Good afternoon,

I'm facing a problem which I can't understand.

I do exec loader.sce and the files does not run until de end because it says that I should 'define function %c_a_ce'. And I really can't understand why.

I will send in below the email the code writen in the file 'loader.sce' in order to be easier to find out the problem.

"-> // Working directory

--> wdir = pwd();

--> // Loading blocks

--> mprintf(gettext("Loading blocks...\n"));
Loading blocks...

--> loadXcosLibs();

--> toolbox_dir = pathconvert(wdir);

--> // All the available block

--> names = {'Pipe','Junction','Reservoir'};

--> interfaces = names;

--> sciFiles = pathconvert(wdir) + interfaces + ".sci";
in builtin exec( C:\Users\tiago.soares\Downloads\Hydraulic_toolbox\loader.sce line -1 )

Undefined operation for the given operands.
check or define function %c_a_ce for overloading."

The loader.sce file is:

'

/ Load a palette in the Xcos environment
clc

// Working directory
wdir = pwd();

// Loading blocks
mprintf(gettext("Loading blocks...\n"));

loadXcosLibs();

toolbox_dir = pathconvert(wdir);
// All the available block
names = {'Pipe','Junction','Reservoir'};
interfaces = names;

sciFiles = pathconvert(wdir) + interfaces + ".sci";
h5_instances = toolbox_dir + "/images/h5/" + interfaces + ".sod";
pal_icons = toolbox_dir + "/images/png/" + interfaces + ".png";
graph_icons = toolbox_dir + "/images/svg/" + interfaces + ".svg";
// graph_icons = interfaces + ".svg";

xpal = xcosPal("WDS");

for i=1:size(interfaces,2)
    // Load the interface function
    exec(sciFiles(i), -1);
    
    // register to the palette.
    style = struct();
    // protect drive letter
    block_img =  graph_icons(i);
    if getos() == "Windows" then
        block_img = "/" + block_img;
    end
    style.image = "file://" + block_img;
    xpal = xcosPalAddBlock(xpal, h5_instances(i), pal_icons(i), style);
end

xcosPalAdd(xpal);

global %MODELICA_USER_LIBS;
%MODELICA_USER_LIBS = [%MODELICA_USER_LIBS ; pathconvert(wdir)];'
