This seems to be a known problem that was reported over a year ago: https://savannah.nongnu.org/bugs/?58194 A patch was submitted to display an intelligible warning along with a suggestion for fixing the documenation, but nothing has been done with either. If I had a clue, I would submit a patch for BUILDING, but I think it's clear I don't. -- Grant _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
