```meson
gen2 = generator(someprog,
outputs : ['@BASENAME@.c', '@BASENAME@.h'],
- arguments : ['--out_dir=@BUILD_DIR@', '@INPUT@']
+ arguments : ['--out_dir=@BUILD_DIR@', '@INPUT@'])
```
In this case you can not use the plain `@OUTPUT@` variable, as it would be ambiguous. This program only needs to know the output directory, it will generate the file names by itself.
