"avr/pgmspace.h: No such file or directory" on ESP8266.

[R0dri]

I am using this library together with my NodeMCU and other ESP8266-12 modules.
But the library/compiler throws the following error: "fatal error: avr/pgmspace.h: No such file or directory".

I found the following solution:

at ros.h I replaced

#include <avr\pgmspace.h>

with

#if (defined(AVR))
#include <avr\pgmspace.h>
#else
#include <pgmspace.h>
#endif

This solution was suggested by: https://github.com/SodaqMoja/Sodaq_DS3231/issues/5 having a similar issue with another library.

I am still getting error, this is the Arduino output console:

Hello, I do not think this issue is related with rosserial because I cannot see mention of `avr/pgmspace.h` in the current [ros.h]( https://github.com/ros-drivers/rosserial/blob/fe1e233f39d56931b5e223c5e53a2d9c2f9fb664/rosserial_arduino/src/ros_lib/ros.h) file. Furthermore we already used ESP8266 board with rosserial without facing this issue. Please, make sure you have a recent version of `rosserial_arduino` (maybe you need to use the git version instead of the one provided by your distribution if it is too old.

I found the following solution: at ros.h you have to replace #include <avr\pgmspace.h> with #if (defined(*AVR*)) #include <avr\pgmspace.h> #else #include <pgmspace.h> #endif This works fine for me.

I'm sorry, you where right. I tried to use the libraries imported by the Arduino IDE library manager. Just downloaded and compiled from source and it worked flawlessly.
