C compiler on target

Hi Pavel,

When I do a configure I see that, its configuring for x86,

../gcc-linaro/configure --disable-bootstrap --enable-languages=c,c++ --with-mode=thumb --with-arch=armv7-a --with-tune=cortex-a9 --with-float=softfp --with-fpu=neon --prefix=/gcc-linaro-install/
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
checking for a BSD-compatible install... /usr/bin/install -c
checking whether ln works... yes
checking whether ln -s works... yes
checking for a sed that does not truncate output... /bin/sed
checking for gawk... gawk
checking for libatomic support... yes
checking for libcilkrts support... yes
checking for libitm support... yes
.....

Cheers,

Mike,

Are you trying the 'configure' and 'make' commands from the target board or from the host PC?

Hi Pavel,

I am running the configure script on host PC.

Mike,

Per mine understanding, 'configure' and 'make' should be executed from within the target platform.

Hi Pavel,

I want to build a native compiler, If I run make and configure on target how will it compile (make will call GCC in target board)

Cheers,
Mike

Mike,

I agree with your point. But if you run make and configure on host PC, you will create a native compiler for the host PC. And I do not see instruction how to transfer this native compiler from the host PC to the target platform.

Seems we do not have official native C compiler for Cortex-A8 ARM based boards. I will also check this with the toolchain team, but there will be delay, as they are out of office these days.

Hi Pavel,

Thanks, I will be waiting for your response.

Cheers,
Mike

Mike,

On the example given we have:

checking build system type... armv7l-unknown-linux-gnueabi
checking host system type... armv7l-unknown-linux-gnueabi
checking target system type... armv7l-unknown-linux-gnueabi

This makes me think this build is for ARM based device, not x86 desktop machine.

Hi Pavel,

Yes the example says 'armv7l-unknown-linux-gnueabi' but what is the point in doing this, if we the target already has the GCC into it.

Cheers,

Mike,

This page seems to instruct how to install Linaro GCC on ARM platform which has already older version of GCC into it. As I am unable to find other native compiler make and install instructions, let us wait for feedback from the toolchain team.
