(unrelated) you can do #+(file-append unzip "/bin/unzip") here. The 'file-append' is not very important here, but the #+ is. The difference between #+ (cf. 'native-inputs) and #$ (cf. 'inputs') is important when cross-compiling. Also, I would use 'invoke' instead of 'system*' here -- 'invoke' throws an exception if it fails (making the derivation fail to build), whereas 'system*' silently returns an integer. > "-d" #$output > #$file)) > #$out)) > ``` > > Is there someting which ressembles the imaginary `name` function > I used above? computed-file-name, local-file-name, package-name ... I don't think there's some generic procedure for this. Greetings, Maxime.
