Hi Chen-Wei,

I have moved this discussion to the OpenCores OpenRISC forum. Please keep all your questions to a forum, so others can benefit from the issues raised. Background for other readers: This question was originally raised on the Open SystemC forum, regarding my application note on wrapping the OpenRISC architectural simulator with a SystemC TLM 2.0 interface (http://www.embecosm.com/download.html). However the question has now moved to building the OpenRISC tool chain on a 64-bit Linux platform, so is more relevant to the OpenRISC mailing list. This appears to be a Linux problem. You are getting a C compiler complaint about: struct rock_ridge { char signature[2]; unsigned char len; unsigned char version; union { struct SU_SP_s SP; struct SU_CE_s CE; struct SU_ER_s ER; struct RR_RR_s RR; struct RR_PX_s PX; struct RR_PN_s PN; struct RR_SL_s SL; struct RR_NM_s NM; struct RR_CL_s CL; struct RR_PL_s PL; struct RR_TF_s TF; struct RR_ZF_s ZF; } u; }; This seems valid C to me. Please could you list the exact details of how you built the OpenCores toolchain, and the platform on which you are building it. I'd like to see each command you used in downloading, unpacking, patching, building and installing binutils, GCC (first time), Linux headers, uClibc, and Linux. Rich D'Addio may have had experience of the OpenCores tools on 64-bit Linux. Best wishes, Jeremy - Tel: +44 (1202) 416955 Cell: +44 (7970) 676050 SkypeID: jeremybennett Email: jeremy.bennett@e...
