Hi,  
    I don't know where to check, I just upgrade arduino IDE and esp core to last version
when I make a almost empty project, as soon I add the webserver #include

#include <Uri.h>
#include <Parsing-impl.h>
#include <ESP8266WebServerSecure.h>
#include <ESP8266WebServer.h>
#include <ESP8266WebServer-impl.h>


The compilation fail with a ton of error starting by


Parsing-impl.h: 64:30: error: expected initializer before '<' token
   _parseRequest(ClientType& client) {
 
Parsing-impl.h: 266:30: error: expected initializer before '<' token
   _collectHeader(const char* headerName, const char* headerValue) {
Parsing-impl.h: In member function void storeArgHandler<ServerType>:perator()(String&, String&, const String&, int, int, int, int)
 
Parsing-impl.h: 281:11: error: 'ESP8266WebServerTemplate' was not declared in this scope
   urlDecode(data.substring(pos, key_end_pos))
Parsing-impl.h:281: note  suggested alternative
 
Parsing-impl.h:25: In file included from
WifiMeteo.ino:4: from
ESP8266WebServer.h:68: note    esp8266webserver  ESP8266WebServerTemplate
   class ESP8266WebServerTemplate

Please I really need help
Thanks

It's a build problem,  Could you told me if I make a project with example the core release 2.5.1
I can't compile it with a core 2.7.1,  it's look like many #include are not the same between
release?  As soon I recompile my code with the old core it is working.

Thanks

Here is the output file,  When I select in VM explorer the core 2.7.1 I have this result, almost all my #include became in error,  if I go back to 2.6.3 the compilation work.

The other part of my question, if I make a project with example the core release 2.6.3
I can't compile it with a core 2.7.1?,  it's look like many #include are not the same between
release?  is there a way to do, it's almost the same each time I upgrade the core.

Thanks for your time

Hi Simon and Tim,

    I didn't had time to try your solution, here in Montreal the weather is Awesome 33 deg full sunshine, so I pass all my time outside, I will give it a try this week, so thanks for your reply, I will give you feedback as soon I can.
