Public bug reported:
I have OpenCL code that works with version 1.0.15468.25-2build1, but
breaks with version 1.0.15468.25-2ubuntu0.1 of libigc1 and libigdfcl1
(on Ubuntu 24.04.2) due to:
error: undefined reference to
_Z37__spirv_ImageSampleExplicitLod_Ruint4PU3AS140__spirv_SampledImage__void_1_0_0_0_0_0_0Dv2_iif'
in function:
'__spirv_ImageSampleExplicitLod_Ruint4(__spirv_SampledImage__void_1_0_0_0_0_0_0
AS1*, int vector[2], int, float)' called by kernel: 'rgb2nv12'
error: backend compiler failed build.
Downgrading the package version of libigc1 and libigdfcl1 to the prior
version fixes the compilation failure. I've appended a small code
example with the first kernel that fails to compile with the new
version.
