A Problem with PostFX and GLSL Functions (v1.6)

[Strobe]

Hi,

I'm trying to implement a simple function in my GLSL shader program, but am met with errors. The version of SFML I am using is 1.6, with Code::Blocks 10.05 for Windows (MinGW).

Here's the offending code:

Code: [Select]

// shader.sfx
texture Img1

float foo(in float fubar)
{
return(fubar);
}

effect
{
_out = Img1(_in);
}

and here are the errors:

Post-effect error : invalid declaration (should be "[type][name]")
> {
Failed to compile post-effect :
(0) : error C0000: syntax error, unexpected $end at token "<EOF>"
(0) : error C0501: type name expected at token "<null atom>"

I suspect SFML isn't properly parsing the shader source. One reason for my belief is that it won't accept the ';' terminator at the end of variable declarations. Another is how this will work:

Code: [Select]

effect
{
_out = Img1(_in);
}

but this will not:

Code: [Select]

effect {
_out = Img1(_in);
}

I've tried not adding ';' at the end of the return line, and also removing 'in,' among other things.

Should I be using SFML 2.0?

thx,

I think so.

Definitely!

Alright, I'll give it a try.

BTW, I tried wrapping code and quote tags around text in my post, but they didn't do anything. But now, there they are. Thanks, if that was your doing

Yeah... you had the "Disable BBCode" box checked

Gah! Thank you  :oops:

Yes! Got 2.0 compiled (which was a surprisingly painless process), and everything is as it should be. Had a difficult patch while trying to compile a program, but I played Tower of Hanoi with the linked libraries until I found the right order.

GLSL shaders now seem to be working as they should Thanks again for everything, Laurent!
