Re: [avr-gcc-list] String array in ROM gives error in spite of following example code.

[Senthil Kumar]

Does

PGM_P  const pgtmp_msg[]    PROGMEM =
   { ptmpUP_msg, ptmpDN_msg,  ptmpCLG_msg,} ;

work? The array itself needs to be declared const, as progmem/flash contents cannot be modified.

That works without out warnings for C.  There was a long standing bug
that you may be running into if you are compiling as C++.
