Hi,

I seem to have a problem in compiling the shaders in the tutorials.
I've learned my lesson and the Main.h file points to the right place. Being as it's the tutorial file, the engine.pak file should also be up-to-date.

Here's the error:

Error compiling shader
"Shader/Shader.cpp"
to file
"/Applications/EsenthelEngineSDK/data\Shader/GL/User/Custom Shader".

I think it's possible you've set incorrect path.

Where did you extract the EsenthelEngineShader.rar ?
Try "/EsenthelEngineShader"
so you have:
"/EsenthelEngineShader/Main.h"

then edit "..\EsenthelEngineSDK\Data\Shader\main.h"
to have:

I guess it must have been the wrong path, because the error message has changed. However, I was sure that it was right. I even copied the path directly from terminal to avoid making any mistakes.

In any case, the error I now get is:
Shader Param "_Material._ambient_specular" not found

I seem to recall that those kind of errors occur when the engine.pak is out of date. However, I've run autoupdate and this hasn't helped. I've also tried ensuring that I'm using the latest version of the shader headers, which I figured might be out of date.

I've also placed the files in the location you recommended.

When are you having this error? (doing what)
There is no "_Material._ambient_specular"
there is only "Material._ambient_specular" which is accessed by shader funcs MaterialSpecular and MaterialAmbient

Are you using CG from this link - http://www.esenthel.com/download/Librari...ry2010.dmg ?
If not, then uninstall previous version, and install that one.

The error occurs as soon as I compile and execute the Tutorial:
1 - Shader Creation

I've just tested the latest Mac SDK shader creation tutorial and it works fine for me.
Do you have the correct CG version installed?

Uninstall yours like specified here - http://forums.developer.nvidia.com/lofiv...t4256.html
Then install this http://www.esenthel.com/download/Librari...ry2010.dmg
rebuild your project

I've tried uninstalling and reinstalling CG.
No luck. I still have the same error.

I'm running OS X Lion. Could the problem be due to an incompatibility between Lion and CG 2.2?

Did you try running the shader tutorials on earlier OS versions? Snow Leopard, Leopard, Tiger?
Is your Lion version is "final", or some "developer preview" (beta) ?

I recall that I ran them fine in Snow Leopard a few months ago.
I am unable to re-test the current files.

My version of Lion is final. It is the one from the App store.

thanks, so it looks like the issue is on Lion only.

I'll upgrade my Mac to Lion soon, and will check it out.

I'll look forward to it. The last two things I have left to do involve the use of infinitely (drawn) planes and this shader thing, so I'm really just waiting on mac stuff now

Incidentally, I seem to recall that there are newer versions of CG available. Is it worth me trying one of them?

you could try, but I don't know if that would help

I'll leave it be then

problem should be solved

Awesome. That does indeed seem to work.

Thanks!
