Hi All,

I want to calculate the upper incomplete gamma function, which I have as a function inside a new model, and use it for further applications. However, I'm running into this error:

/home/slowiko/OpenFOAM/slowiko-1.4/lib/linux64Gcc4DPOpt/libnewModel.so: undefined reference to `Foam::newModel::gammaL(double, Foam::GeometricField<double,>&)'
collect2: ld returned 1 exit status
make: *** [/home/slowiko/OpenFOAM/slowiko-1.4/applications/bin/linux64Gcc4DPOpt/testFoam] Error 1

when I go into the ~/newmodel directory and do a "wmake libso" I don't get any errors. I also tried to "wclean" in the aforementioned directory before the "wmake libso" then a "./Allwmake" (and) a "wmake" after, however this doesn't seem to solve my problem. Any suggestions?

hi,

did you use the "static" keyword somewhere in your class?

Basically, I'm doing some modifications to the two phase euler foam code. This particular model is based on the structure of the phase model (a little more complicated, but similar structure)
the only "static" anything that I used was in the selector:

// Selectors
//- Return a reference to the selected new model
static autoPtr<newmodel> New
(
PtrList<volvectorfield>& U_temp,
PtrList<volscalarfield>& prprty_temp,
const IOdictionary& transdict,
const IOdictionary& prprtydict
);

I should probably say however: I was using a function under the same name earlier. I didn't need it, and deleted it. Later, I added a different function (the gamma function calculated a different way) back.

hi,

i thought it could be a problem with the definition and declaration of static members - which may cause similar errors.

Hello Mateusz,

Your problem is that the .C file containing function definition (function body) for

newModel::gammaL(double, Foam::GeometricField<double,>&)

either did not compile correctly or is not on a list of files but it exists in the header of the class newModel.

If you want to use it, it has got to be defined to make the linker happy; if you do not want it, delete its declaration from the header file.

Hope this helps,

Hrv

Hrv,

Right on the money - I guess a mistake like that serves me right for trying to rush through the code while still being a newbie.. thanks again for the help.

I want to calculate the lower incomplete gamma function, which I have as a function inside a new model too. lower incomplete gamma functions includes a magnitude U. I tried to use gnu math functions but it gave me prameter type error. I stucked that error. Can you help me calculating incomplete gamma.

Best
