-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2012-18369 2012-11-17 02:17:29 --------------------------------------------------------------------------------
Name : avr-libc Product : Fedora 18 Version : 1.8.0 Release : 1.fc18 URL : http://www.nongnu.org/avr-libc/ Summary : C library for use with GCC on Atmel AVR microcontrollers Description : AVR Libc is a Free Software project whose goal is to provide a high quality C library for use with GCC on Atmel AVR microcontrollers. AVR Libc is licensed under a single unified license. This so-called modified Berkeley license is intented to be compatible with most Free Software licenses like the GPL, yet impose as little restrictions for the use of the library in closed-source commercial applications as possible. -------------------------------------------------------------------------------- Update Information: - avr-binutils updated to 2.23.1 with avr format option for avr-size - avr-gcc updated to 4.7.2 with better optimization and more supported MCUs - avr-libc updated to 1.8.0 with PROGMEM fixes Some projects use PROGMEM attribute incorrectly. New avr-gcc version no longer tolerates that, so if you are affected, check your PROGMEM usage. - there's no such thing like PROGMEM variable, it's just some pointer and it depends how(where) you use such variable - PROGMEM just tells compiler where to put initialization data, nothing more, nothing less. So it should be only there, where you initialize your variable. - PROGMEM is no type attribute, so when you use it with type definition, nothing happens. - variable working with PROGMEM data must be always 'const' Wrong PROGMEM usage: const char PROGMEM *foo; typedef char PROGMEM *progchar; void foo(const char *PROGMEM abc); The only correct usage: const char *progstring; const char *progstring PROGMEM = "hello world"; Because PROGMEM does not affect type declaration, avr-libc dropped all prog_char, prog_* types. If you need them for some reason, use #define __PROG_TYPES_COMPAT__ (two underlines before and after, autoformating removed them). You still need to make sure, you have PROGMEM where needed (hint grep your code for "prog_.*=" and make sure you have PROGMEM specified where you initialize with data) and also make sure that all variables are 'const'. const char *s can contain both standard and progmem data, so it's good for better readability to define your own "progmem" types, it won't affect the code, but you'll immediately see that such variable is supposed to work with progmem data. -------------------------------------------------------------------------------- References: [ 1 ] Bug #851660 - avr-size missing -C (avr) option https://bugzilla.redhat.com/show_bug.cgi?id=851660 -------------------------------------------------------------------------------- This update can be installed with the "yum" update program. Use su -c 'yum update avr-libc' at the command line. For more information, refer to "Managing Software with yum", available at http://docs.fedoraproject.org/yum/.
