hello,
Im trying to build myself an arm toolchain that will run on my standard
linux box (the x86_64 machine). Im not quite there yet. Here are my
thoughts and process, se if you can spot the problem.
First i need to build binutils that will un on my machine, but link for
the arm, i used
../binutils-2.20/configure --target=arm-elf --prefix=/usr/devel/arm-kit/
--disable-nls --disable-werror
(i ran this comand from in my binutils-build directory).
That ran fine, and now i have my linker and other bits to create my arm
executables on my x86_64 machine.
next was gcc, this was a little tricky, i used gcc-4.4.2, i finally got
it working with a bit of jigery pokery, with this command:
AS_FOR_TARGET=/usr/devel/arm-kit/bin/arm-elf-as
AR_FOR_TARGET=/usr/devel/arm-kit/bin/arm-elf-ar
LD_FOR_TARGET=/usr/devel/arm-kit/bin/arm-elf-ld
NM_FOR_TARGET=/usr/devel/arm-kit/bin/arm-elf-nm
OBJDUMP_FOR_TARGET=/usr/devel/arm-kit/bin/arm-elf-objdump
RANLIB_FOR_TARGET=/usr/devel/arm-kit/bin/arm-elf-ranlib
STRIP_FOR_TARGET=/usr/devel/arm-kit/bin/arm-elf-strip
../gcc-4.4.2/configure --target=arm-elf --prefix=/usr/devel/arm-kit/
--disable-multilib --disable-decimal-float --disable-threads
--disable-libmudflap --disable-libssp --disable-libgomp
--enable-languages=c
(i ran this command from within my gcc-build directory)
note that i set the target linker and what-not using environment
variables. This seems to have not completely worked as there was a
script thats part of the build system that needed mofifying (i think).
It was
/usr/arm-build/gcc-build/./gcc/as
It didnt have have the variable set called
ORIGINAL_AS_FOR_TARGET=""
ORIGINAL_LD_FOR_TARGET=""
ORIGINAL_NM_FOR_TARGET="
I got an error abut not being able determine object file extensions, it
was down to the exec command being called without args, as the above
variable werent set, i set them, to:
ORIGINAL_AS_FOR_TARGET="/usr/devel/arm-kit/bin/arm-elf-as"
ORIGINAL_LD_FOR_TARGET="/usr/devel/arm-kit/bin/arm-elf-ld"
ORIGINAL_NM_FOR_TARGET="/usr/devel/arm-kit/bin/arm-elf-nm"
this worked ! now onot glibc, i used glibc-2.11, and compiled it with
this:
../glibc-2.11/configure --target=arm-elf --prefix=/usr/devel/arm-kit/
--exec-prefix=/usr/devel/arm-kit/ --enable-add-ons
--with-binutils=/usr/devel/arm-kit/bin/ --host=x86_64-unknown-linux-gnu
--build=arm-elf --without-selinux --with-elf
i ran this from within my glibc-build directory.
this seemed ok, so i installed. Now the thing is i can comile object
files, and the file command reports them as
tmp.o: ELF 32-bit LSB relocatable, ARM, version 1, not stripped
which seems good, but hen i try and create an executable i get:
/usr/devel/arm-kit/bin/arm-elf-gcc-4.4.2 tmp.c -I
/usr/devel/arm-kit/include/
/usr/devel/arm-kit/bin/../lib/gcc/arm-elf/4.4.2/../../../../arm-elf/bin/ld:
crt0.o: No such file: No such file or directory
collect2: ld returned 1 exit status
bt if i just amke an object file it seems ok:
/usr/devel/arm-kit/bin/arm-elf-gcc-4.4.2 tmp.c -I
/usr/devel/arm-kit/include/ -c
no problem, so has nayone got any ideas of what my problem is ? i assume
if compiled binutils a bit wrong or something ?
cheers
Dave
