[Mesa-users] Uniform block in mesa glsl-compiler

[Y.Audureau]

Hi,

I am a new user of mesa.
I would like to use the standalone glsl-compiler but I got some issues
while compiling a glsl 300 es fragment shader with a simple uniform block
inside :

uniform barBlock {
    vec4 nv;
    int ni;
} inst;

I got the following message :
"error: invalid stream specified 0 is larger than MAX_VERTEX_STREAMS - 1
(-1)."

It seems that the MAX_VERTEX_STREAMS is not set and that the stream
property of my ubo layout (layout.stream) is setted to 0 because the it
doesn't have any stream expression. But in any case, my shader is a
fragment shader, not a geometry one and in version 300 es.

If I define MAX_VERTEX_STREAMS, I got others issue about the others layout
properties (buffer, offset, stride, align) but why those properties are
checked if I don't use the enhanced layout extension.

I deduced those informations from the function (in ast_to_hir.cpp) :
ir_rvalue *
ast_interface_block::hir(exec_list *instructions,  struct
_mesa_glsl_parse_state *state)


Thanks
