Windowsでうまく動作するプログラムをUbuntu 11.04でコンパイルしようとしていますが、上記のエラーが発生します。エラーの原因となっている行にコメントを追加しました。コードは次のとおりです。
route_input() {
int num_routes;//Variable to act as the loop counter for the loop getting route details
int x;
char route_id[3];

char r_destination[20];

scanf("%d", &num_routes);
char routes_arr[num_routes][10];//An array to hold the details of each route
printf("\nNumber of routes is %d\n", num_routes);
struct route r[num_routes];//An array of structures of type route (This line causes the error)
