Hi all,First of all, sorry for my poor english.I am working on c5soc but I would like to compile hello_world kernel. I am on windows 7 64.When I invoke : aoc --board c5soc device/hello_world.cl -o bin/hello_world.aocxI get an error which is : Error qsys-script failed. Before this, I have :aoc: Environment checks are completed successfully.You are now compiling the full flow!!aoc: Selected target board c5socaoc: Running OpenCL parser....aoc: OpenCL parser completed successfully.aoc: Compiling....aoc: Linking with IP library ...aoc: First stage compilation completed successfully.aoc: Setting up project for QXP preservation flow....The errors are reported in hello_world.log :System name: hello_worldPlacing kernel hello_world at address 0x02015.06.02.09:51:12 Info: Doing: qsys-script --script=system.tcl --xmx512m --xx:+useserialgc --system-file=system.qsysInternal Error: Sub-system: DYGR, File: /quartus/ddb/dygr/dygr_fitter_delay_info_drl_interface.cpp, Line: 299Cannot load library ddb_dygr_fdi.dll: La procédure spécifiée est introuvable.Stack Trace: 0x39dd2: DYGR_ROUTE_TIMING_INFO::get_timing_node + 0x94a2 (DDB_DYGR) 0x20ad8: dygr_fdi_drl_call_mem_new + 0x8 (DDB_DYGR) 0x209ef: DYGR_DIE_INFO_BODY::DYGR_DIE_INFO_BODY + 0x1bf (DDB_DYGR) 0x207b5: dygr_create_die_info + 0x55 (DDB_DYGR) 0xe6a3: dmgr_create_device_for_pintable_update + 0xcc53 (DDB_DMGR) 0x10240: dmgr_create_device_for_pintable_update + 0xe7f0 (DDB_DMGR) 0x1171f: dmgr_create_device_for_pintable_update + 0xfccf (DDB_DMGR) 0x11bf3: dmgr_create_device_for_pintable_update + 0x101a3 (DDB_DMGR) 0x189e: DMGR_UTILITY::create_device + 0x6e (DDB_DMGR) 0xd202: pll_get_reference_clock_frequency_range + 0xaa2 (qcl_pll) 0xd5f7: generic_pll_parse_tcl_data + 0xd7 (qcl_pll) 0x112a8: Tcl_ListMathFuncs + 0x5a8 (tcl85) 0x56917: Tcl_ExprObj + 0x1837 (tcl85) 0xa2376: TclObjInterpProcCore + 0x76 (tcl85) 0x112a8: Tcl_ListMathFuncs + 0x5a8 (tcl85) 0x56917: Tcl_ExprObj + 0x1837 (tcl85) 0xa2376: TclObjInterpProcCore + 0x76 (tcl85) 0x112a8: Tcl_ListMathFuncs + 0x5a8 (tcl85) 0x121b5: Tcl_EvalEx + 0x8f5 (tcl85) 0x129b9: Tcl_Eval + 0x29 (tcl85) 0x1a47: Java_com_altera_tcl_interpreter_NativeTclWrapper_eval0 + 0x67 (tcl_jni_bridge)End-traceInternal Error: Sub-system: DMGR, File: /quartus/ddb/dmgr/dmgr_utility_body.cpp, Line: 2932ref_count >= 0Stack Trace: 0x113b5: dmgr_create_device_for_pintable_update + 0xf965 (DDB_DMGR) 0x114b3: dmgr_create_device_for_pintable_update + 0xfa63 (DDB_DMGR) 0x128bf: dmgr_create_device_for_pintable_update + 0x10e6f (DDB_DMGR) 0x13fde: dmgr_create_device_for_pintable_update + 0x1258e (DDB_DMGR) 0x14228: dmgr_create_device_for_pintable_update + 0x127d8 (DDB_DMGR) 0x23ab0: LdrShutdownProcess + 0x1d0 (ntdll) 0x238bf: RtlExitUserProcess + 0x8f (ntdll) 0x20ccc: _get_pgmptr + 0x248 (MSVCR100) 0x1dac: err_ie_abort_or_exit + 0x1c (CCL_ERR) 0x33407: MSG_INTERNAL_ERROR::update_comment_and_send_crash_report + 0x2f57 (CCL_MSG) 0x334e2: MSG_INTERNAL_ERROR::report + 0xd2 (CCL_MSG) 0x39dd2: DYGR_ROUTE_TIMING_INFO::get_timing_node + 0x94a2 (DDB_DYGR) 0x20ad8: dygr_fdi_drl_call_mem_new + 0x8 (DDB_DYGR) 0x209ef: DYGR_DIE_INFO_BODY::DYGR_DIE_INFO_BODY + 0x1bf (DDB_DYGR) 0x207b5: dygr_create_die_info + 0x55 (DDB_DYGR) 0xe6a3: dmgr_create_device_for_pintable_update + 0xcc53 (DDB_DMGR) 0x10240: dmgr_create_device_for_pintable_update + 0xe7f0 (DDB_DMGR) 0x1171f: dmgr_create_device_for_pintable_update + 0xfccf (DDB_DMGR) 0x11bf3: dmgr_create_device_for_pintable_update + 0x101a3 (DDB_DMGR) 0x189e: DMGR_UTILITY::create_device + 0x6e (DDB_DMGR) 0xd202: pll_get_reference_clock_frequency_range + 0xaa2 (qcl_pll) 0xd5f7: generic_pll_parse_tcl_data + 0xd7 (qcl_pll) 0x112a8: Tcl_ListMathFuncs + 0x5a8 (tcl85) 0x56917: Tcl_ExprObj + 0x1837 (tcl85) 0xa2376: TclObjInterpProcCore + 0x76 (tcl85) 0x112a8: Tcl_ListMathFuncs + 0x5a8 (tcl85) 0x56917: Tcl_ExprObj + 0x1837 (tcl85) 0xa2376: TclObjInterpProcCore + 0x76 (tcl85) 0x112a8: Tcl_ListMathFuncs + 0x5a8 (tcl85) 0x121b5: Tcl_EvalEx + 0x8f5 (tcl85) 0x129b9: Tcl_Eval + 0x29 (tcl85) 0x1a47: Java_com_altera_tcl_interpreter_NativeTclWrapper_eval0 + 0x67 (tcl_jni_bridge)End-traceThanks for your help
