buildModel fails with template error (from CodeGenUtil.tpl)
buildModel fails with template error (from CodeGenUtil.tpl)
I get the following error trying to build this model. And I am struggling to find the source of the problem with no success.
Please let me know how I can resolve this error.
(I built OpenModelica from svn sources - rev. 1.9.3+dev (r25926) - on a Linux box - "Linux vishnu 3.19.8-100.fc20.x86_64 #1 SMP Tue May 12 17:08:50 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux", with gcc (GCC) 4.8.3 20140911 (Red Hat 4.8.3-7)

Thank you
Re: buildModel fails with template error (from CodeGenUtil.tpl)
Since I last submitted the post I found the source of the problem in buildModel phase. It appears that the translated (replaceable) function "solve: from the Media.Common.OneNonLinearEquation package has a stray statement that fails compilation of the translated function. Below is the short segment of the code snipped from the "plant_functions.c" file.
if(((fabs(_m) <= _tol) || (_fb == 0.0)))
{
_found = 1;
// 0.0 = 1; ..... This is the stray line I had to comment out for the "make" to succeed,
_x_zero = _b;
I am able identify the corresponding Modelica code in the function is shown .(Attaching a small screenshot of OMEdit session) .
My gut feeling says that it is a bug in the translator.

Hi,
I now opened a ticket about this:
https://trac.openmodelica.org/OpenModelica/ticket/3390
and hopefully we'll get to the bottom of this.
Cheers,
Adrian Pop/
