Hello. I'm writing an application, that combines GTK calls (from C source) and fortran subroutine. Behavior of subroutine depends on when it gets called - before gtk_init or after. If it is called before gtk_init, subroutine works OK. If subroutine is called after gtk_init, fortran behaves very strange: it reads floating point value from file, but it gets only integer part of it. In first, correct case, it reads normal floating point value. Code >printf("This call is correct:\n"); >main_in_ (); >gtk_init (&args_length1, &args); >printf("And this is already broken:\n"); >main_in_ (); Gives following output >This call is correct: > dt == 7.30000019E-11 >And this is already broken: > dt == 7.0000000 Why does gtk_init affect fortran way of reading value? How it can be fixed? Small testcase attached. |
