Body
I cannot run the following code in native mode. The error message is displayed when I try: <blockquote> Warning: this system is not configured for native-code compilation. escript: exception error: no function clause matching test_escript_1383_893414_479613:main([]) (./test, line 5) in function escript:run/2 (escript.erl, line 747) in call from escript:start/1 (escript.erl, line 277) in call from init:start_it/1 in call from init:start_em/1 </blockquote> How can I configure my system to run it in native mode? Code: <pre><code>#!/usr/bin/env escript -mode(native). %% to fun faster main([NStr]) -> N = list_to_integer(NStr), IJ = [{I, J} || I <- lists:seq(1, N), J <- lists:seq(1, N)], lists:foreach(fun({I, J}) -> put_data(I, J, true) end, IJ), solve(N, 1, [], 0). solve(N, J, Board, Count) when N < J -> print(N, Board), Count + 1; solve(N, J, Board, Count) -> F = fun(I, Cnt) -> case get_data(I, J) of true -> put_data(I, J, false), Cnt2 = solve(N, J+1, [I|Board], Cnt), put_data(I, J, true), Cnt2; false -> Cnt end end, lists:foldl(F, Count, lists:seq(1, N)). put_data(I, J, Bool) -> put({row, I }, Bool), put({add, I+J}, Bool), put({sub, I-J}, Bool). get_data(I, J) -> get({row, I}) andalso get({add, I+J}) andalso get({sub, I-J}). print(N, Board) -> Frame = "+-" ++ string:copies("--", N) ++ "+", io:format("~s~n", [Frame]), lists:foreach(fun(I) -> print_line(N, I) end, Board), io:format("~s~n", [Frame]). print_line(N, I) -> F = fun(X, S) when X == I -> "Q " ++ S; (_, S) -> ". " ++ S end, Line = lists:foldl(F, "", lists:seq(1, N)), io:format("| ~s|~n", [Line]). </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
