by using build macro `LZ4_PUBLISH_STATIC_FUNCTIONS`.
#### Amalgamation
lz4 code is able to be amalgamated into a single file.
We can combine all source code in `lz4_all.c` by using following command,
```
cat lz4.c > lz4_all.c
cat lz4hc.c >> lz4_all.c
cat lz4frame.c >> lz4_all.c
```
and compile `lz4_all.c`.
It's necessary to include all `*.h` files present in `/lib` together with `lz4_all.c`.
#### Windows : using MinGW+MSYS to create DLL
DLL can be created using MinGW+MSYS with the `make liblz4` command.
