FYI: Another IDE include error

Development Libraries
1

Apparently, conditional includes are always used by the IDE to identify "required" library files. Consider this example:

#if 0
  #include <NeoHWSerial.h>
#endif

void setup()
{
  Serial.begin( 9600 );
}

void loop() {}

This seems to trick the IDE into linking in NeoHWSerial, even when the condition is FALSE. As a result, HardwareSerial (via 'Serial') conflicts with the incorrectly linked NeoHWSerial. Simply commenting out the NeoHWSerial include removes the "require" of that library, and HardwareSerial links in correctly:

#if 0
  //#include <NeoHWSerial.h>
#endif

void setup()
{
  Serial.begin( 9600 );
}

void loop() {}

Sigh. This behavior might be related to this. This is still a problem in 1.6.5r2

I opened an issue for this.

Cheers,
