Error compiling

Hi, I'm having problems when I tried to compile the examples codes.

Build options changed, rebuilding all

Error compiling.

Is this issue related to my Arduino version (1.60). I'm on OSX 10.9.5. I hope you can help me, thanks.

I am getting the same error on a linux box running 1.0.5 - but I uploaded the library to codebender.cc
and it compiled correctly. So I figured it was my machine as I've had some issues with the linux IDE before
but if other people are seeing the same error, then it can't just be me!

I think it's something related with Arduino 1.6. I installed the 1.0.6 version and it works!

Hello,

It doesn't compile with modern compilers because data in flash (PROGMEM) must be declared as const. But it's easy to fix : 1 - in examples add 'const' on each PROGMEM array declarations
2 - fix talkie.cpp line 91by adding a cast : setPtr((uint8_t*) addr);

hi @sylvainf ,

i tried your fix, changed this in the "getting started" example:
"const uint8_t spDANGER[] PROGMEM = {0x2D, 0xBF, 0x21, 0x92, 0x59,..."
and tried to change in the talkie.cpp, but in line 91 there is no such line.
thus, i changed the one in 97 from
"setPtr(addr);"
to
"setPtr((uint8_t*) addr);"
in the talkie::say routine

however, then i get this error:

error: invalid conversion from 'const uint8_t* {aka const unsigned char_}' to 'uint8_t_ {aka unsigned char_}' [-fpermissive]
In file included from talkie_demo1.ino:14:0:
\Arduino\libraries\Talkie/talkie.h:15:8: error: initializing argument 1 of 'void Talkie::say(uint8_t_)' [-fpermissive]
void say(uint8_t* address);

don't know what to do now. any ideas? (i'm running arduino ide 1.5.8)

Ok, you must modify the prototype too : in talkie.h replace "void say(uint8_t* address);'' by "void say(const uint8_t* address);"
