support for at90usb1287 device broken

[Andrew Straw]

Binary package hint: avr-libc

Since version 1.4.4, avr-libc has supported the at90usb1287 device, among others ( http://www.nongnu.org/avr-libc/NEWS.txt ). However, the version in ubuntu gutsy, 1.4.5, fails to work with this device.

Steps to reproduce:

1) Create the source for a simple C program (example below).
2) avr-gcc -c -mmcu=at90usb1287 -gdwarf-2 -Os test.c -o test.o
3) avr-gcc -mmcu=at90usb1287 -gdwarf-2 test.o --output test.elf -lm

Now, I get the error:

/usr/lib/gcc/avr/4.2.1/../../../../avr/bin/ld: crtusb1287.o: No such file: No such file or directory

Note that this example builds fine on Debian unstable, which is using avr-libc-1.4.6.

Now, for the source of the simple C program, test.c:

#include <avr/io.h>
#include <avr/interrupt.h>

int main(void)
{

  uint8_t x;

  while (1)
  {
      x++;
  }
}

Confirming, I get the same error with avr-libc 1.4.5. 1.4.6 from debain unstable also works for me.

1.4.6 has been synced from debian, however its not building due to bug(s) in sbuild. (debian bug numbers #403246, #422879, #272955). Anyone know how 1.4.6 is built in debian? I cant seem to find any build logs for it...

crttn84.o and crttn85.o are also missing (attiny84 and attiny85, respectively) from avr-libc 1.4.5-2

Rebuilding the package (on Gutsy) led to happiness :)

1. apt-get source avr-libc
2. cd avr-libc-1.4.5
3. change debian/rules line 9ish to
      ./configure --build=`./config.guess` --host=avr --prefix=/usr --enable-doc --disable-versioned-doc --disable-pdf-doc --disable-ps-doc
4. dpkg-buildpackage -rfakeroot
dpkg -i ../avr-libc_1.4.5-3_all.deb

[Troy C (troxor)]

Works fine for me now, using standard Hardy packages.

$ dpkg -l | grep avr
ii avr-libc 1:1.4.7-1 Standard C library for Atmel AVR development
ii binutils-avr 2.18-3 Binary utilities supporting Atmel's AVR targ
ii gcc-avr 1:4.2.2-1 The GNU C compiler (cross compiler for avr)

Could you test with avr-libc 1:1.6.7-1 available in Ubuntu Lucid, please?

Thanks!

[Andrew Straw (astraw)]

The following commands work without raising an exit code on Lucid avr-libc 1:1.6.7-1 amd64, Lucid avr-libc 1:1.6.7-1 i386, Karmic 1:1.6.2.cvs20080610-2 amd64, and sid 1:1.6.7-1 amd64:

git clone git://github.com/motmot/fview_ext_trig.git

cd fview_ext_trig/CamTrigUSB/Projects
rm -f MotmotCamTrig/*.hex MotmotCamTrig/*.o
make -C MotmotCamTrig

Therefore, I think this bug can be considered closed.

Thanks Andrew!
