Combine the flour and pecans in a bowl. In another bowl, beat the butter with the sugars, vanilla and salt until light and fluffy. Add the flour and pecans and mix on low speed just until combined. Divide the dough into thirds.
On a lightly floured surface, roll each portion of dough into a 12-inch log. Wrap each log in plastic and refrigerate until firm.
Preheat the oven to 350°. Slice the logs 1/4 inch thick and bake on cookie sheets for 10 minutes, or until golden. Let the cookies cool on the sheets for 10 minutes, then transfer them to racks to cool completely.
The logs can be frozen for up to 1 month. Defrost before slicing and baking. The baked cookies can be stored in an airtight container for up to 4 days.
