I am also working on using newlib for aarch64 and see that it gives a
crt0.o file. From reading forums, I think this should be used as the
startup files (vs using gcc's crt1.o and crti.o, crtn.o crtend.o)
So my new script compiling a simple hello world for aarch64 is as follows:
INPUT=$1
aarch64-linux-gnu-gcc -c -o ${INPUT%.c}_ARMObj.o $1
echo -e " ------------ x86 OBJECT FILE OBTAINED... \n\n\n\n"
aarch64-linux-gnu-gcc -v -nostdlib -static -o rARM64 \
/home/bielsk1/aarch64-toolchain/ARM_newlib/aarch64-unknown-linux-gnu/lib/crt0.o
\
/home/bielsk1/aarch64-toolchain/ARM_newlib/aarch64-unknown-linux-gnu/lib/libnosys.a
\
/home/bielsk1/aarch64-toolchain/ARM_newlib/aarch64-unknown-linux-gnu/lib/librdimon.a
\
${INPUT%.c}_ARMObj.o \
-I/home/bielsk1/aarch64-toolchain/ARM_newlib/aarch64-unknown-linux-gnu/include \
-L/home/bielsk1/aarch64-toolchain/ARM_newlib/aarch64-unknown-linux-gnu/lib \
/home/bielsk1/aarch64-toolchain/ARM_newlib/aarch64-unknown-linux-gnu/lib/libc.a
\
/home/bielsk1/aarch64-toolchain/ARM_newlib/aarch64-unknown-linux-gnu/lib/libg.a
\
/home/bielsk1/aarch64-toolchain/ARM_newlib/aarch64-unknown-linux-gnu/lib/libm.a
\
-lc -lm
this now presents the following error:
/home/bielsk1/aarch64-toolchain/ARM_newlib/aarch64-unknown-linux-gnu/lib/crt0.o:

/home/bielsk1/aarch64-toolchain/libgloss_ARMbuild/aarch64/../../newlib-2.1.0/libgloss/aarch64/crt0.S:156:

so what am I missing??? Do I have to write these functions myself for aarch64?
Thank you for your time,
