    ARB_sample_shading: Add test to verify the functionality of gl_SampleMask[]
    V2: Get rid of redundant projection matrix.
    V3: Draw to a multisample texture and use it later to verify
        the expected color of each sample.
        Use piglit_draw_rect() and get rid of redundant code.
        Use piglit_vertex in vertex shader.
        Use piglit_link_simple_program().

Comment 1 Brian Paul 2013-12-12 16:00:42 UTC
Evidently, the C++ lib's asprintf() is clashing with Piglit's implementation in piglit-util.c

But we're not seeing this with our in-house build of piglit on mingw64.

Any ideas, Jose?

Vinson, could you try something like this in piglit_util.c and see what happens:

 /* Some versions of MinGW are missing _vscprintf's declaration, although they

The patch in comment #1 fixes the build on Fedora.

commit 52bce82ddb8fc4b2dce95af0908abf4054591b77
Author: Vinson Lee <vlee@freedesktop.org>

    cmake: Check for asprintf.
    Newer versions of MinGW provide asprintf in stdio.h. Do not define
    asprintf if it already exists.
    This patch fixes the Fedora 20 MinGW build.
