### Compile
You can use the default compile if you intend to use cpuminer-opt on the
same CPU and the virtual machine supports that architecture.
Compile for the CPU architecture of the host machine:
`$ ./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:
To compile for a specific CPU architecture:
CFLAGS="-O3 -march=znver1 -Wall" ./configure --with-curl
`CFLAGS="-O3 -march=znver1 -Wall" ./configure $CONFIGURE_ARGS`
This will compile for AMD Ryzen.
You can compile more generically for a set of specific CPU features
if you know what features you want:
CFLAGS="-O3 -maes -msse4.2 -Wall" ./configure --with-curl
`CFLAGS="-O3 -maes -msse4.2 -Wall" ./configure `$CONFIGURE_ARGS`
This will compile for an older CPU that does not have AVX.
You can find several examples in build-allarch.sh
You can find several examples in README.txt
If you have a CPU with more than 64 threads and Windows 7 or higher you
can enable the CPU Groups feature:
can enable the CPU Groups feature by adding the following to CFLAGS:
-D_WIN32_WINNT==0x0601
`-D_WIN32_WINNT==0x0601`
Once you have run configure successfully run make with n CPU threads:
