Re: [avr-llvm-devel] AVR-LLVM on ARM?

[John M. <ato...@gm...>]

I can't get cmake+ninja to even create the makefile. It says that the c++
compiler is broken (unable to compile a simple program), both with clang
and gcc.

I tried using configure and gcc which will create the makefile if I remove
the -Wcovered-switch-default switch. But the build fails with a bunch of
undefined references when trying to link the FileCheck program.

If I try with configure and clang I get a link error like yours were it
complains about the binary format for ELF not being correct.
I tried both with and without AVR as the target but it didn't seem to
change anything.
