This is odd, this function is pretty old. > /usr/local/lib64/libOpenCL.so: undefined reference to > `llvm::LLVMContext::setDiagnosticHandler(void (*)(llvm::DiagnosticInfo > const&, void*), void*, bool)@LLVM_6.0' > collect2: error: ld returned 1 exit status > make: *** [Makefile:10: hello_world] Fehler 1 > > Greetings, > Dieter > > For reference (running '/opt/amdgpu-pro/bin/clinfo'): > > /opt/opencl-example> /opt/amdgpu-pro/bin/clinfo > /opt/amdgpu-pro/bin/clinfo: /usr/local/lib64/libOpenCL.so.1: no version > information available (required by /opt/amdgpu-pro/bin/clinfo) > /opt/amdgpu-pro/bin/clinfo: /usr/local/lib64/libOpenCL.so.1: no version > information available (required by /opt/amdgpu-pro/bin/clinfo) > ATTENTION: default value of option mesa_glthread overridden by > environment. > ATTENTION: default value of option radeonsi_assume_no_z_fights > overridden by environment. > ATTENTION: default value of option radeonsi_commutative_blend_add > overridden by environment. > ATTENTION: default value of option mesa_glthread overridden by > environment. > Number of platforms: 1 > Platform Profile: FULL_PROFILE > Platform Version: OpenCL 1.1 Mesa > 17.3.0-devel (git-94fef19509) > Platform Name: Clover > Platform Vendor: Mesa > Platform Extensions: cl_khr_icd > > > Platform Name: Clover > Number of devices: 1 > Device Type: CL_DEVICE_TYPE_GPU > Vendor ID: 1002h > Max compute units: 36 > Max work items dimensions: 3 > Max work items[0]: 256 > Max work items[1]: 256 > Max work items[2]: 256 > Max work group size: 256 > Preferred vector width char: 16 > Preferred vector width short: 8 > Preferred vector width int: 4 > Preferred vector width long: 2 > Preferred vector width float: 4 > Preferred vector width double: 2 > Native vector width char: 16 > Native vector width short: 8 > Native vector width int: 4 > Native vector width long: 2 > Native vector width float: 4 > Native vector width double: 2 > Max clock frequency: 1411Mhz > Address bits: 64 > Max memory allocation: 6010904166 > Image support: No > Max size of kernel argument: 1024 > Alignment (bits) of base address: 1024 > Minimum alignment (bytes) for any datatype: 128 > Single precision floating point capability > Denorms: No > Quiet NaNs: Yes > Round to nearest even: Yes > Round to zero: No > Round to +ve and infinity: No > IEEE754-2008 fused multiply-add: No > Cache type: None > Cache line size: 0 > Cache size: 0 > Global memory size: 8587005952 > Constant buffer size: 2147483647 > Max number of constant args: 16 > Local memory type: Scratchpad > Local memory size: 32768 > /opt/amdgpu-pro/bin/clinfo: relocation error: > /usr/local/lib64/libOpenCL.so.1: symbol > _ZN4llvm11LLVMContext20setDiagnosticHandlerEPFvRKNS_14DiagnosticInfoEPvES4_b, > version LLVM_6.0 not defined in file libLLVM-6.0svn.so with link time > reference this looks like libLLVM-6.0svn.so is an older version than what you built clover against. Did you rebuild and reinstall llvm after r313390?
