Follow-up Comment #6, bug #28837 (project avr-libc): > Backport the gcc fix :-) > it looks like it could be quite a while before it becomes > available by normal upgrade.
avr-gcc's PR34734 <http://gcc.gnu.org/PR34734> is fixed in 4.6.2 and GCC 4.6.2 is available, see http://gcc.gnu.org/gcc-4.6 Bugfixes in avr-gcc are not backported to all versions supported by GCC because of avr-gcc developer shortage. That is: Bugfixes are only backported from current development trunk (4.7 at the moment) to 4.6. Even if there was a backport to 4.5, you would still have to get a 4.5.3 distribution or build it yourself, anyway, as it won't tunnel into your local installation by magic ;-) #define PROGMEM __attribute__(( section(".progmem.data"))) PROGMEM const char string1[] = "String 1"; PROGMEM char string2[] = "String 2"; > error: string2 causes a section type conflict This is not a avt-libc bug because it is not a PROGMEM define from avr-libc. And GCC is correect about complaining: Section attributes are drawn from data properties and they are different but the data is put into the same section. Using a new compiler version together with the original progmem attribute, this will result in an error, too, because it is no more legitimate to use attribute progmem in non-const data. If you like to write to the data by, say, a bootloader then the data is to be qualified as volatile const. _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?28837> _______________________________________________ Nachricht geschickt von/durch Savannah http://savannah.nongnu.org/ _______________________________________________ AVR-libc-dev mailing list AVR-libc-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/avr-libc-dev
