Hello, I encountered a bug with the Gentoo-patches of avr-libc. When compiling with crossdev: acer [~]: crossdev -s3 -t avr Crossdev (I'm using crossdev-0.9.15) emerges the packages as it's supposed to do: ---------------------------------------------------------------------------------------------------------------------------- * Host Portage ARCH: x86 * Target Portage ARCH: x86 * Target System: avr * Stage: 3 (C compiler & libc) * binutils: binutils-2.16.1-r2 * gcc: gcc-3.4.6 * libc: avr-libc-[latest] * PORTDIR_OVERLAY: /usr/local/portage * PORT_LOGDIR: /var/log/portage * PKGDIR: /usr/portage/packages/cross/avr * PORTAGE_TMPDIR: /var/tmp/cross/avr _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ * Forcing the latest versions of binutils-config/gcc-config ...

[ ok ] * Log: /var/log/portage/cross-avr-avr-libc.log * Emerging cross-avr-libc ... Finally, the following packages are merged: cross-avr/binutils-2.16.1-r2 cross-avr/gcc-3.4.6 cross-avr/avr-libc-1.4.4 Then, when trying to use avr-gcc, compiling works fine, but when trying to link a project: avr-gcc -Wall -Werror -Wunused -Wuninitialized -Wno-inline -Os -mmcu=at90s8515 -DF_CPU=7372800UL -I/usr/avr/include -I../Libraries -o "TempGrid" "TempGrid.c" Tools.o CRC8.o BitBanging.o DynamicMemory.o ROMCommands.o FuncCommands.o RS232.o Intro.o MemCheck.o ../Libraries/LibLCD/LibLCD.a /usr/lib/gcc/avr/3.4.6/../../../../avr/bin/ld: skipping incompatible /usr/lib/gcc/avr/3.4.6/../../../../avr/lib/libc.a when searching for -lc /usr/lib/gcc/avr/3.4.6/../../../../avr/bin/ld: skipping incompatible /usr/avr/binutils-bin/2.16.1/../../lib/libc.a when searching for -lc /usr/lib/gcc/avr/3.4.6/../../../../avr/bin/ld: cannot find -lc make: *** [TempGrid] Error 1 What's happened with /usr/avr/lib/libc.a? # file /usr/avr/lib/libc.a /usr/avr/lib/libc.a: current ar archive # avr-ar tv /usr/avr/lib/libc.a rw-r--r-- 0/0 690 Aug 21 16:48 2006 abs.o rw-r--r-- 0/0 5308 Aug 21 16:48 2006 assert.o rw-r--r-- 0/0 3608 Aug 21 16:48 2006 bsearch.o rw-r--r-- 0/0 3140 Aug 21 16:48 2006 calloc.o rw-r--r-- 0/0 2340 Aug 21 16:48 2006 errno.o rw-r--r-- 0/0 2868 Aug 21 16:48 2006 labs.o rw-r--r-- 0/0 6664 Aug 21 16:48 2006 malloc.o rw-r--r-- 0/0 5912 Aug 21 16:48 2006 qsort.o rw-r--r-- 0/0 3896 Aug 21 16:48 2006 rand.o rw-r--r-- 0/0 3976 Aug 21 16:48 2006 random.o rw-r--r-- 0/0 6164 Aug 21 16:48 2006 realloc.o [...] # avr-ar xv /usr/avr/lib/libc.a malloc.o x - malloc.o # avr-ar p /usr/avr/lib/libc.a malloc.o > malloc.o # file malloc.o malloc.o: ELF 32-bit LSB relocatable, version 1 (SYSV), not stripped # avr-objdump -d malloc.o malloc.o: file format elf32-avr Disassembly of section .text: 00000000 <malloc>: 0: cf 93 push r28 2: df 93 push r29 4: 48 2f mov r20, r24 6: 59 2f mov r21, r25 8: 02 97 sbiw r24, 0x02 ; 2 a: 10 f4 brcc .+4 ; 0x10 <malloc+0x10> c: 42 e0 ldi r20, 0x02 ; 2 e: 50 e0 ldi r21, 0x00 ; 0 [...] # So the libc.a is looking good... hmm... When I unmerged the avr-libc 1.4.4, compiled it manually without first applying any patches, it worked perfectly. So therefore I suspect an error within the Gentoo-patches. Compiling avr-libc manually will do for a workaround, but it's no real good solution. BTW, how can you force crossdev to remerge packages? It just does nothing when the package is already merged - very annoying behaviour! Feel free to ask if you have any further questions. I've already talked to upstream about that problem (because I falsely suspected the problem there first), the according reference is at http://lists.gnu.org/archive/html/avr-gcc-list/2006-08/msg00042.html - I'll also post a message linking to this bug report there.

I have confirmed that this is an issue on my machine, however the ebuild for the latest version does not appear to apply any patches. It seems portage does something weird during the emerge process...

I also see this. I think it's because portage calls i686-pc-linux-gnu-strip on the lib before installing. After adding RESTRICT="strip" to the ebuild it seems to work. -Erik

Created an attachment (id=97204) [details] avr-libc-strip.patch i havent tested this patch but this is the method utilized in glibc/uclibc/newlib/etc...
This patch did not work, leaving it unstripped seems to be necessary at this point.
no, you just need to make sure you strip the libs with the proper toolchain
1.4.4 should be fixed in cvs now
