[Bug bootstrap/67373] Can't compile gcc snapshot for avr target with mingw
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67373 --- Comment #5 from Senthil Kumar Selvaraj --- The last released version of avr-libc (1.8.1) doesn't properly work with the spec file based device support approach introduced in 5.x. As the GCC 5 release notes (https://gcc.gnu.org/gcc-5/changes.html) describes The AVR port uses a new scheme to describe supported devices: For each supported device the compiler provides a device-specific spec file. If the compiler is used together with AVR-LibC, this requires at least GCC 5.2 and a version of AVR-LibC which implements feature #44574. Can you try building with the trunk version of avr-libc? That should work fine.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67373 Jonas Jelten changed: What|Removed |Added CC||jj at stusta dot net --- Comment #3 from Jonas Jelten --- I got the same problem: avr-gcc -mmcu=atmega8 -O3 -T /usr/lib64/binutils/avr/2.25.1/ldscripts/avr4.xn -Wl,-Map=blingbling.map blingbling.o -o blingbling.elf /usr/libexec/gcc/avr/ld: cannot find crtatmega8.o: No such file or directory /usr/libexec/gcc/avr/ld: cannot find -latmega8 collect2: error: ld returned 1 exit status ... The -T option was required so gcc finds the linker script, without it, it crashes even earlier: avr-gcc -mmcu=atmega8 -O3 -Wl,-Map=blingbling.map blingbling.o -o blingbling.elf /usr/libexec/gcc/avr/ld: cannot open linker script file ldscripts/avr4.xn: No such file or directory collect2: error: ld returned 1 exit status Any idea how to fix that?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67373 --- Comment #4 from Jonas Jelten --- It should be noted that my issue occurs on Gentoo with gcc 5.3.0, avr-libc 1.8.1 and avr binutils 2.25.1-r1.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67373 --- Comment #2 from kontakt at michaelstather dot com --- Thank you very much, compiling works now. But, I get linker errors. With gcc4.9.2 it works fine, but both with 5.2 and 6 I get e.g.: C:\AVRTools4Windows\share\doc\avr-libc-1.8.1\examples\demo>make avr-gcc -g -Wall -O2 -mmcu=atmega8-c -o demo.o demo.c avr-gcc -g -Wall -O2 -mmcu=atmega8 -Wl,-Map,demo.map -o demo.elf demo.o c:/avrtools4windows/bin/../lib/gcc/avr/6.0.0/../../../../avr/bin/ld.exe: cannot find crtatmega8.o: No such file or directory c:/avrtools4windows/bin/../lib/gcc/avr/6.0.0/../../../../avr/bin/ld.exe: cannot find -latmega8 collect2.exe: error: ld returned 1 exit status Makefile:75: recipe for target 'demo.elf' failed make: *** [demo.elf] Error 1 The file crtatmega8.o doesn't seem to exist. Other target mcus give similar errors.

Building binutils with host=mingw creates an assembler that can only run on Windows. Can you try building binutils without setting host=mingw, add that to the PATH and then try building again?
