ok, also try adding ci.getHeaderSearchOpts().ResourceDir = "path/to/clang";

Hi Sam,
After I remove the /usr/include path.
5 kinds of errors dispear. But there is still one error left, /sandbox/xiuxia/llvm_build/Debug+Asserts/lib/clang/3.4/include/mm_malloc.h:27:10: fatal error: 'stdlib.h' file not found.
stdlib is under /usr/include , and it include lots of other heads which is also located in /usr/include.
Thanks,
Xiuxia

Ok, so we're getting somewhere! i'd remove the /usr/include from your search path too, i suspect there's a conflict and kernels shouldn't need anything that
isn't included from clc.h - i think.
Looking at your kernels, I'd also remove the includes too. and if MMD_floatK3 are just a renaming for float3 - why not just use the float3 specifier?
hope that helps,

Hi Sam,
Thanks for your advice. I've tried to include clang header path instead of gcc header, and it works, and the compiler doesn't complain the following 2 kinds of errors anymore:
1. unknown builtin '__builtin_ia32_cmpneqps'
2. error: invalid conversion between vector type '__m128' and integer type 'int' of different size
However there are some other 5 kinds of errors reported as before,
/usr/include/stdlib.h:337:4: error: unknown type name 'size_t'; did you mean 'ssize_t'?
/usr/include/stdlib.h:857:20: error: unknown type name 'wchar_t'
/sandbox/xiuxia/llvm_build/Debug+Asserts/lib/clang/3.4/include/mm_malloc.h:33:44: error: unknown type name 'size_t'; did you mean 'ssize_t'?
/usr/include/CL/cl.h:562:17: error: redefinition of parameter 'size_t'
/sandbox/xiuxia/libclc/libclc/generic/include/clc/integer/abs.inc:1:41: error: conflicting types for 'abs'
atom_kernel.h:45:24: error: invalid operands to binary expression ('MMD_floatK3' (aka 'struct sdouble3') and 'MMD_floatK3')
I am not very familiar with clang, and find it is difficult to find materials about how to learning clang. I feel perplexed when encounter this kind of problems. Hope you could give me some suggestions.
Best,
Xiuxia

Hi,
Have you ensured you are meeting this requirement?
// <Warning!!> -- Platform Specific Code lives here

// Search through Clang itself for something like this,

// See somewhere around Driver.cpp:77 to see Clang adding
// its version of the headers to its include path.
you're using the gcc include path, and i've always used the clang path instead.
cheers,

Hi Sam,
Thanks for your reply and suggestions.
I followed your suggestion, and add necessary source code to CI_opencl.cpp
and input file. However there are same problems.
Here is my input file(atom_kernel.h) and clang consumer file(CI_opencl.cpp)
and error output (error.output). Makefile is the same.
almost the same error. Compiler still complain types and sse instructions
missing.
Thanks,
Xiuxia
