Hi

I'm facing a problem with LwIP configration, while i copied the code from the examples and tried many times to add the header files path to the project include options and file paths search with no result.

Then i changed the security permissions for the header file on the disk with same result, how this case can be solved?

    Since the line in the code is:

    #include "lwip/opt.h"

    the path specified to the compiler's include path options (Project Properties->Build->Compiler->Include Options, --include_path) should be C:\ti\tivaware_c_series_2_1_4_178\third_party\lwip-1.4.1\src\include (or the equivalent for your version of TivaWare).

    Is that what you have in your project? If yes and if the errors still persist, then please save the complete build log from the build console to a file and attach it here.
