Come posso passare i parametri a gcc in Rust with Cargo?

Question

Sto provando a creare rust-sfml con carico, ma il mio gcc non riesce a trovare le librerie richieste.

Voglio risolvere il problema passando -L opzioni a gcc, ma non riesco a trovare alcun modo conveniente per farlo.

Esiste qualche soluzione semplice tranne l'utilizzo di uno script di compilazione?

$ cargo run

Answer 1

Probabilmente è necessario installare le librerie C SFML prima di provare a compilare i binding Rust. rug-sfml è solo il binding di Rust, non installa SFML stesso.

Answer 2

Impostare una variabile di ambiente LIBRARY_PATH che contenga la directory alla quale si sta tentando di fare riferimento.
