I installed uDrawGraph 3.1.1 and I am trying to call it from Ciao Prolog, it runs uDrawGraph but hang and does not return to my prolog code. Note: Ciao Prolog is compatible with old daVinci. I changed the library in Ciao to call: uDrawGraph -pipe Example: In prolog: m :- exec('uDrawGraph -pipe', Input, Output, Error), get_code(O, C), get_code(O, C1), get_code(O, C2), [C,C1]="ok", ..... The above program will run uDrawGraph and get the work ok, but it hangs there, (i.e. not returns to my code to continue the rest of the code. Any help. Respectively Omar.
