 Create the file using the shell script:
 ```
 cd zstd/contrib/declib
-./combine.sh -r "../../lib ../../lib/common ../../lib/decompress" zstddeclib-in.c > zstddeclib.c
+./combine.sh -r ../../lib -r ../../lib/common -r ../../lib/decompress -o zstddeclib.c zstddeclib-in.c
 ```
 Then add the resulting file to your project (see the [test sources](tests) for examples).
