arduino DUE and uHTTP librairy doesn't work

Using Arduino Programming Questions

Hi..

Just working on a sketch using an arduino DUE, ethernet shield and I'd like to incorporated the uHTTP librairy.

But when I tryed the example include with the lib, It doesn't compile when the arduino DUE is selected but it does when it is UNO.

this is the error send by the compiler:

Build options changed, rebuilding all

The DUE has a lot more memory than the UNO. You don't need to use PROGMEM on the DUE. So, don't.

The DUE has a lot more memory than the UNO. You don't need to use PROGMEM on the DUE. So, don't.

I never use that function, it include inside the library. I found couple of place that it used, always something like this:

bool uHTTP::uri(const __FlashStringHelper *uri){
	return (strcmp_P(this->uri(), (const PROGMEM char *) uri) == 0) ? true : false;

}

There is many thing I do not understand in that function so... how could i remove the progmem? should I just erase it and left 'const char *' ?

thank

how could i remove the progmem?

bool uHTTP::uri(const char*uri)
{
	return (strcmp(this->uri(), (const char *) uri) == 0) ? true : false;
}

Ya! I don't believe it !! I've been able to modify the library. I only tried so far to use doc_root example and get the index.htm, so I don't know if other feature still work. I chunk it a lot

So I post code here if anyone find something wrong or want to test it.
