It compiles without error on my win7-64 bit pc, but fail when I attempt to compile on my Raspberry Pi. The error is
/usr/share/arduino/libraries/Time/DateStrings.cpp:41:22: error: variable ‘monthNames_P’ must be const in order to be put into read-only section by means of ‘attribute((progmem))’
/usr/share/arduino/libraries/Time/DateStrings.cpp:58:20: error: variable ‘dayNames_P’ must be const in order to be put into read-only section by means of ‘attribute((progmem))’
/usr/share/arduino/libraries/Time/DateStrings.cpp:59:24: error: variable ‘dayShortNames_P’ must be const in order to be put into read-only section by means of ‘attribute((progmem))’
Any ideas?
