PROGMEM Demo on Arduino.cc Will not Compile?

Using Arduino Programming Questions
1

Is there something wrong with the configuration of my machine(s) such that the demo of PROGMEM from the below page does not compile on Ubuntu or on a Raspberry Pi running Debian (but does compile on a MAC)?

The error that I am getting is that prog_char does not define a type.

Thanks for any help,

It compiles for me using IDE 1.0.4
I copied it from the link you gave. It is 58 lines long including the block comments at the top. Are you sure that you copied all of it ?

I assume that you do have the pgmspace.h file. Which version of the IDE are you using ?

HeliBob:

I am running IDE 1.0.1 on all three machines that I have tried including the one that works (with all 58 lines of the sketch!). This appears to be the latest version packaged in apt-get for Ubuntu and Debian as the installs are new.

I do seem to have the pgmspace.h file:

-rw-r--r-- 1 root root 41927 May 23 2012 /usr/lib/avr/include/avr/pgmspace.h

Assuming that is the right place for it!

Sorry but I can offer no help about where the file should be on a Linux system but others will be able to help I am sure.
