framebuffer object HELP!!

[Mr.Pink]

i want to implement SHADOW MAPPING and GLOW post processing using FBO and GLSL
for shadow mapping i use these fbo settings:


glGenFramebuffersEXT(1, &fbo);

//create depth textures
glGenTextures(1, &depth);
glBindTexture(GL_TEXTURE_2D, depth);
glTexImage2D(GL_TEXTURE_2D, 0, GL_DEPTH_COMPONENT, shadowMapWidth, shadowMapHeight, 0, GL_DEPTH_COMPONENT, GL_FLOAT, NULL);

//set texture quality
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);

//bind fbo and attach depth texture to it
glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, fbo);
glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_DEPTH_ATTACHMENT_EXT, GL_TEXTURE_2D, depth, 0);

glDrawBuffer(GL_NONE);
glReadBuffer(GL_NONE);

// my check routine
verifyFBO();

and everything is OK---> framebuffer is complete!
then i try to setup another fbo for POST PROCESSING, like this:

glGenFramebuffersEXT(1, &fbo2);

glGenTextures(2, color);
glBindTexture(GL_TEXTURE_2D, color[0]);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB8, offscreenSize, offscreenSize, 0,
GL_RGB, GL_UNSIGNED_BYTE, NULL);
glBindTexture(GL_TEXTURE_2D, color[1]);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB8, offscreenSize, offscreenSize, 0,
GL_RGB, GL_UNSIGNED_BYTE, NULL);

glGenRenderbuffersEXT(1, &depth2);
glBindRenderbufferEXT(GL_RENDERBUFFER_EXT, depth2);
glRenderbufferStorageEXT(GL_RENDERBUFFER_EXT, GL_DEPTH_COMPONENT, offscreenSize, offscreenSize);

glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, fbo2);

glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_COLOR_ATTACHMENT0_EXT,
GL_TEXTURE_2D, color[0], 0);
glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_COLOR_ATTACHMENT1_EXT,
GL_TEXTURE_2D, color[1], 0);

glFramebufferRenderbufferEXT(GL_FRAMEBUFFER_EXT, GL_DEPTH_ATTACHMENT_EXT, GL_RENDERBUFFER_EXT, depth2);

verifyFBO();



but i get GL_FRAMEBUFFER_UNSUPPORTED_EXT error!!!!!!!!!!!!

my video card is GeForce 7800GT, Forceware 92.91, dx 9.0c

Instead of GL_DEPTH_COMPONENT, try a specific size, like GL_DEPTH_COMPONENT16 or GL_DEPTH_COMPONENT24.

thanks for reply, i tried to change size format for each attachment but i get the same error.
I even tried to attach a stencil buffer, but it shouldn' t be mandatory afaik.
