Hi,
Any help would be appreciated with a recent upgrade to 1.6.9 IDE with a sketch now failing to compile. Changing the variable name enables the compile but I am unclear as to why this code is a problem. To target the problem away from general code problems and find the issue I cut the sketch down to a single const variable declaration and still get the following error message
"exit status 1
expected unqualified-id before numeric constant" with the following sketch. [actually just the int definition].
const int BUFSIZ =90;
void setup() {
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
changing the const int to another name allows the compile to take place or even just changing the case. I have updated many of the libraries with the IDE [love that feature] but get the following error message which leads me to think it is a library issue.
Arduino: 1.6.9 (Windows XP), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

I have read several forums about avr issues and I am not certain if this is a library installation/upgrade issue or an IDE configuration issue, or a bug within a library. What is interesting is that it is associated only with this definition of BUFSIZ as another variable name compiles fine. I know that I can change the variable BUFSIZ name but have a lot of sketches using this variable and I am wondering if the other error messages can lead to a solution. Is BUFSIZ now a reserved word in IDE 1.6.9?
Changing to BUFSIZe compiles ok.
I am using a Mega and the IDE on an windows XP machine with multiple drives. Any advice would be greatly appreciated or any suggestions for me to look into. Thanks in advance. Chris
