# Re-distribution of this library¶

## Contain Komega in your program¶

$$K\omega$$ library is distributed with the Lesser General Public License (LGPL). It is summarized as follows:

• $$K\omega$$ can be freely distributed, modified, copied and pasted, in a private program (in the research group, co-workers, etc.).

• For the released program (open-source, free, commercial software etc.):

• When you contain the source-code of $$K\omega$$ (either as is and modified) in the distributed source code of your program, please distribute your program with LGPL/GPL.
• If you do not include the source-code of $$K\omega$$ (just call it), you can freely distribute your program with any licenses.
• If you distribute a binary file which is statically linked to $$K\omega$$ library, please use LGPL/GPL. However, if you distribute a binary file which is dynamically linked to $$K\omega$$ library (therefore $$K\omega$$ itself is not contained), you can freely distribute your binary file with any licenses.

## Build Komega without Autoconf¶

In this package, $$K\omega$$ is built with Autotools (Autoconf, Automake, Libtool). If you do not want to use Autotools for your distributed program with $$K\omega$$ source, you can use the following simple Makefile (please care about TAB).

FFLAGS = -fopenmp -g -O2 #-D__MPI -D__NO_ZDOT -D__KOMEGA_THREAD

Preprocessor macros __MPI, __NO_ZDOT, and __KOMEGA_THREAD correspond to --with-mpi=yes, --disable-zdot, and --enable-thread of the options of configure, respectively.
