You are right, I posted the warnings only, sorry:( The error is that
ld fails to find a compatible libmingw32. I don't have the log here
right now, but can produce it if you like? Here a bit more information
from my original post [0]:
There are more identical errors for other libs like kernel32 and msvcrt.
objdump lists the correct format:
[cut]/build/root/bin/x86_64-w64-mingw32-objdump --archive-headers \
[cut]/build/root/x86_64-w64-mingw32/lib/libmingw32.a
[...]
lib64_libmingw32_a-tlsmcrt.o: file format pe-x86-64
Also, ld seems to be valid:
[cut]/build/root/bin/x86_64-w64-mingw32-ld: supported targets: \
pe-x86-64 pei-x86-64 elf64-x86-64 elf64-l1om elf64-little elf64-big \
elf32-little elf32-big srec symbolsrec verilog tekhex binary ihex
Thanks JonY for your feedback!
