### Compile ### Compile
You can use the default compile if you intend to use cpuminer-opt on the Compile for the CPU architecture of the host machine:
same CPU and the virtual machine supports that architecture.
`$ ./build.sh` `CFLAGS="-O3 -march=native -Wall" ./configure $CONFIGURE_ARGS`
Otherwise you can compile manually while setting options in CFLAGS. or cross compile for a specific CPU architecture:
Some common options: `CFLAGS="-O3 -march=znver1 -Wall" ./configure $CONFIGURE_ARGS`
To compile for a specific CPU architecture:
CFLAGS="-O3 -march=znver1 -Wall" ./configure --with-curl
This will compile for AMD Ryzen. This will compile for AMD Ryzen.
