Compiler error in ESP8266 Version 2.0 beta 2

#1 
Arduino:1.6.9 (Linux), Tarjeta:"Generic ESP8266 Module, 80 MHz, 40MHz, DIO, 115200, 512K (64K SPIFFS), ck, Disabled, None"

/root/Arduino/ulisp-esp8266/ulisp/ulisp.ino: In function 'object* fn_max(object*, object*)':
ulisp:1761: error: 'max' was not declared in this scope
     result = max(result,integer(car(args)));
#2

The Arduino core defines max, min, and abs as macros:

#define min(a,b) ((a)<(b)?(a):(b))
#define max(a,b) ((a)>(b)?(a):(b))
#define abs(x) ((x)>0?(x):-(x))

I’m not sure why you’re not picking these up, but you could try adding these definitions to the beginning of the uLisp source file.

Hello update the arduino ide from version 1.6.5 to 1.8.5 and the problem was solved. I was also able to install ulisp on the esp8266 v1 of 512k.
Gracias Che.
