GCC Running On Tablet

[tasinofan]

just for fun and out of curiosity, I cross built some unix commands on my amd64 gentoo desktop to run on arm-none-linux-gnueabi

autoconf-2.69
automake-1.13.1
binutils-2.23.2
busybox-1.21.0
curl-7.29.0
gcc-4.8.0
gdb-7.5.1
gmp-5.1.1
gnutls-3.1.10
hello-2.8
libtasn1-3.3
libtool-2.4.2
m4-1.4.16
make-3.82
mpc-1.0.1
mpfr-3.1.2
ncurses-5.9
nettle-2.6
openssh-6.2p1
openssl-1.0.1e
proftpd-1.3.4c
readline-6.2
rsync-3.0.9
wget-1.14
zlib-1.2.7

On the tablet, together with arm cross glibc-2.17 and linux-headers-3.8, I can now, for example, compile:
I guess it should work fine on many android devices


(it needs some setup for LIBRARY PATH and some symbolic links to make tablet believe there is a /usr/arm-none-linux-gnueabi)

# gcc -v
Using built-in specs.

# cat > hello.c
#include <stdio.h>
#include <stdlib.h>
#include <stddef.h>

int main (int argc, char **argv) {

printf("hello world\n");
exit (0);
}
^D
# gcc -o hello hello.c
# ./hello
hello world

# cat > hello.cc
using namespace std;
#include <iostream>
#include <vector>
#include <stdlib.h>
int main(int argc, char **argv)
{
cout << "hello C++" << endl;
exit(0);
}
^D
# g++ -o hello hello.cc
# ./hello
hello C++


update: I also ported GNU build tools so I can build, say, GNU hello doing

# tar zxf hello-2.8.tar.gz
# cd hello-2.8
# ./configure --prefix=/usr/arm-none-linux-gnueabi
# make -j 5
# make install --prefix=/usr/arm-none-linux-gnueabi


update: gdb works now also:

# g++ -g -o hello hello.cc
# gdb ./hello

Can it also work on lenovo tab model a3300-gv?

Hi nivek, all devices that run arm-none-linux-gnueabi cross compiled software are fine.
I think that's almost all 32bit arm devices. I never asked myself if arm-none-linux-gnueabi built programs would run on a2109/a2110, they simply did. Of course, for any program one needs all shared libraries. Therefore, eventually, I chose to have a distro in a chroot. In my case the distro was gentoo (which one needs to build oneself). Also because some programs (e.g. perl) are hard to cross compile, I indeed run qemu now for maintaining the arm distro on amd64. Of course, qemu is slow as compared to cross but it works.

ok thnx...
are you using turbo c++??
How i going to install it to my tab??

Really thnx for sharing youre information to me...
