Hi everyone,

I have a vertex shader where I declare a vec4 array as varying

here is a code snippet :

varying vec4 projCoord[8];

...

void main(){

...

projCoord[0] = biasMat * m_LightViewProjectionMatrix0 * worldPos;
projCoord[1] = biasMat * m_LightViewProjectionMatrix1 * worldPos;
projCoord[2] = biasMat * m_LightViewProjectionMatrix2 * worldPos;
projCoord[3] = biasMat * m_LightViewProjectionMatrix3 * worldPos;
projCoord[4] = biasMat * m_LightViewProjectionMatrix4 * worldPos;
projCoord[5] = biasMat * m_LightViewProjectionMatrix5 * worldPos;
projCoord[6] = biasMat * m_LightViewProjectionMatrix6 * worldPos;
projCoord[7] = biasMat * m_LightViewProjectionMatrix7 * worldPos;

}

This woks fine on Windows with ATI or Nvidia cards, but on Mac OS i have this compilation error :

ERROR: 0:36: 'assign' : cannot convert from '4-component vector of float' to 'float'
ERROR: 0:38: 'assign' : cannot convert from '4-component vector of float' to 'float'
ERROR: 0:40: 'assign' : cannot convert from '4-component vector of float' to 'float'

ERROR: 0:46: '[' : vector field selection out of range '5'
ERROR: 0:46: 'assign' : cannot convert from '4-component vector of float' to 'float'
ERROR: 0:48: '[' : vector field selection out of range '6'
ERROR: 0:48: 'assign' : cannot convert from '4-component vector of float' to 'float'
ERROR: 0:50: '[' : vector field selection out of range '7'
ERROR: 0:50: 'assign' : cannot convert from '4-component vector of float' to 'float'

It seems that the compiler is considering projCoord as a single vec4 and not an array of vec4

As anyone bumped into a similar problem?
Or maybe i'm doing something wrong?

Here are the complete system spec on which the error appears :
MacBook Pro Core i7 with a NVIDIA GeForce GT 330M Card, MacOSX 10.6.4 with the latest driver patch (Graphics Update 1.0 for Snow Leopard) from Apple installed.
