Is there a way to use VEX code as a string in hou.runVex?

[magneto]

Hi,

 

I am trying to use hou.runVex but it seems to require a vex file, which is supposed to be compiled using vcc. This seems to convoluted when you just want to make a simple function call.

 

I did it anyway but now I am getting "The attempted operation failed". I searched online but couldn't find any example of how it's used. I am passing {} for the second argument as my function doesn't take any arguments except the "export float out = 0".

 

Is it actually working?

 

 

Thanks

Hi Edward, I tried it from there already but it doesn't seem to work. As you know you have to compile the code into vex first, and after that I am getting a generic error calling the file.

<shrugs> If the documented example doesn't work, then there's a bug somewhere here.

Thanks Edward, I submitted it. I imagine this function is not used a lot so a bug is quite possible. Even in the forums there is a mention of it but no example.

hou.runVex() works as long as you don´t pass any string to vex but this never really worked afaik.

Thank you very much, petz!
I use your example file for run VEX in 64-bit mode, as described in http://www.sidefx.com/docs/houdini/hom/hou/runVex.html
It works, so in houdini 17, i can print a long value, calculated in VOP SOP, without overflow!
