When I try to start cgminer on windows it throws the following error:

cgminer –-scrypt -o http://netcodepool.org:8337 -u usernmae -p mypass –-thread-concurrency 8192 -I 10 -g 1 -w 256

:687: error: no matching overload found for arguments of type 'unsigned int  __attribute__((ext_vector_type(

                        B[i+4] = EndianSwap(tmp[i]);

  • Take all the extra parameters out of your command line and let cgminer use the default settings: cgminer –-scrypt -o http://netcodepool.org:8337 -u usernmae -p mypass

If you using a Nvidia card you should use cudaMiner since you will get better hash rates for it. https://bitcointalk.org/index.php?topic=167229.0


What kind of graphics card do you have? Check out the bitcointalk forum post about this (https://bitcointalk.org/index.php?topic=171515.0)

Basically, "The auto gpu and fan settings are only for ATI cards I believe." If you have a different one, perhaps change your settings.
