@ -54,10 +54,15 @@ Building OpenBLAS requires the following to be installed:
Simply invoking `make` (or `gmake` on BSD) will detect the CPU automatically.
To set a specific target CPU, use `make TARGET=xxx`, e.g. `make TARGET=NEHALEM`.
The full target list is in the file `TargetList.txt`. For building with `cmake`, the
usual conventions apply, i.e. create a build directory either underneath the toplevel
OpenBLAS source directory or separate from it, and invoke `cmake` there with the path
to the source tree and any build options you plan to set.
The full target list is in the file `TargetList.txt`, other build optionss are documented in Makefile.rule and
can either be set there (typically by removing the comment character from the respective line), or used on the
`make` command line.
Note that when you run `make install` after building, you need to repeat all command line options you provided to `make`
in the build step, as some settings like the supported maximum number of threads are automatically derived from the
build host by default, which might not be what you want.
For building with `cmake`, the usual conventions apply, i.e. create a build directory either underneath the toplevel
OpenBLAS source directory or separate from it, and invoke `cmake` there with the path to the source tree and any
