We should probably fix that. tools_def.template mentions arm-linux-gnueabi, and while it does not really matter in most cases, if you are using Clang, you actually need the armel binutils (see 41203b9ab5d48e029f24e17e9a865e54b7e1643d for details) > Force the armhf cross toolchain prefix on Debian distributions. > > [1] https://www.debian.org/ports/arm/#status > [2] > https://github.com/tianocore/edk2-platforms/blob/master/Readme.md#if-cross-compiling > > Signed-off-by: Philippe Mathieu-Daudé <phi...@redhat.com> > --- > roms/edk2-funcs.sh | 3 +++ > 1 file changed, 3 insertions(+) > > diff --git a/roms/edk2-funcs.sh b/roms/edk2-funcs.sh > index 3f4485b201..a546aa1d11 100644 > --- a/roms/edk2-funcs.sh > +++ b/roms/edk2-funcs.sh > @@ -112,6 +112,9 @@ qemu_edk2_get_cross_prefix() > ( [ "$gcc_arch" == i686 ] && [ "$host_arch" == x86_64 ] ); then > # no cross-compiler needed > : > + elif ( [ -e /etc/debian_version ] && [ "$gcc_arch" == arm ] ); then > + # force hard-float cross-compiler on Debian > + printf 'arm-linux-gnueabihf-' > else > printf '%s-linux-gnu-\n' "$gcc_arch" > fi > -- > 2.21.0 >
