I'd like to start mining Bitcoins on a CPU for testing purposes. I've downloaded CGMiner, compiled it and created a config file without any problems, however starting it results in an error message:
All devices disabled, cannot mine!
What do I need to do in order for CGMiner to consider my CPU a device?
When building the source use:
./configure --enable-cpumining && make
At the end of the configure stage you will see a list of what has been enabled, like this:
------------------------------------------------------------------------
cgminer 2.9.6
------------------------------------------------------------------------
Configuration Options Summary:
curses.TUI...........: FOUND: -lncurses
OpenCL...............: NOT FOUND. GPU mining support DISABLED
scrypt...............: Disabled (needs OpenCL)
ADL..................: SDK NOT found, GPU monitoring support DISABLED
BitForce.FPGAs.......: Disabled
Icarus.FPGAs.........: Disabled
ModMiner.FPGAs.......: Disabled
Ztex.FPGAs...........: Disabled
CPU Mining...........: Enabled
ASM.(for CPU mining).: true
Compilation............: make (or gmake)
CPPFLAGS.............:
CFLAGS...............: -g -O2
LDFLAGS..............: -lpthread
LDADD................: -lcurl compat/jansson/libjansson.a -lpthread -lm
Installation...........: make install (as root if needed, with 'su' or 'sudo')
prefix...............: /usr/local
You can get a list of supported options with ./configure --help (standard behavior for configure)
CPU mining is no longer supported. See CGMiner FAQ:
Q: What happened to CPU mining?
A: Being increasingly irrelevant for most users, and a maintenance issue, it is no longer under active development and will not be supported. No binary builds supporting CPU mining will be released. Virtually all remaining users of CPU mining are as back ends for illegal botnets. The main reason cgminer is being inappopriately tagged as a virus by antivirus software is due to the trojans packaging a CPU mining capable version of it. There is no longer ANY CPU mining code in cgminer. If you are mining bitcoin with CPU today, you are spending 1000x more in electricity costs than you are earning in bitcoin.
