Problem with hcustom

[faxingberlin]

I start HDK with hucstom.

I read HDK: Getting Started. ( http://www.sidefx.com/docs/hdk14.0/_h_d_k__intro__getting_started.html )

 

 

I compile geoisosurface.C in Window 8.1

 

#include <GU/GU_Detail.h>

#include <stddef.h>

 

namespace HDK_Sample {

 

static float

densityFunction(const UT_Vector3 &P, void *data)

{

    // Return the signed distance to the unit sphere

    return 1 - P.length();

}

 

}

 

int

main(int argc, char *argv[])

{

    GU_Detail gdp;

    UT_BoundingBox bounds;

 

    // Evaluate the iso-surface inside this bounding box

    bounds.setBounds(-1, -1, -1, 1, 1, 1);

 

    // Create an iso-surface

    gdp.polyIsoSurface(HDK_Sample::densityFunction, NULL, bounds, 20, 20, 20);

 

    // Save to sphere.bgeo

    gdp.save("sphere.bgeo", NULL);

 

    return 0;

}

 

 

But,,, sphere.bgeo didn't appear..

 

 

On the other hand, I compile geoisosurface.C in Ubutu 15.04 . sphere. bgeo appears.

 

I check Windows Environment Variables, System Variables.. I don't know why ... Please help me..

I would bet Windows just put it somewhere else.

 

Try using an absolute path  gdp.save("C:\\Users\\ *computers name* \\Desktop\\sphere.bgeo" , NULL);  that should drop it right on your desktop.

Thank you for your answer, Tom

I change the path.

 

gdp.save("C:\\Users\\Hyunjun\\Desktop\\sphere.bgeo", NULL);

 

But, the sphere.bgeo didn't appear... I really don't know.. Can I re-install Houdini, Visual Studio 2012??

[MrScienceOfficer]

Did you run the executable?

[faxingberlin]

I run geoisosurface.exe. The system error appears. ( There is no libGA.dll)

[MrScienceOfficer]

If your running a standalone application, you will have to copy houdini's dll's into the projects directory for your standalone.  Or move your exe into houdini's directory.

[faxingberlin]

I did..   xxxxxx.dll file locate C:\Program Files\Side Effects Software\Houdini 14.0.395\bin 

I move exe, O file .. I execute again.. It appears at once.. Nothing happened..

[MrScienceOfficer]

Actually that's my bad, you don't have write permission to write in the bin folder, but if you kept the absolute path it would work, it worked for me.  

 

To keep the relative path, you would have to move all the dll's out.  You shouldn't have to though, according to the Docs it should find the DLLs, but it didn't work for me either.  Its sounds like an issue with environment variables on windows 8.1, as I'm using it as well.

It sounds like it's being linked dynamically rather than statically. Try adding --ldflags to the hcustom command line to see if it's linking against the libs in usolib (static) vs dsolib (dynamic).

Thank you! Tom, Edward. I try again 

[faxingberlin]

Finally! I solve the problem!! Thank you very very much!!
