Cross compilation ?

[Guest Mark Jackson]

I'm interested in cross compiling code on the Vega platform (more as a linux dev kit rather than for doing Android apps).

Is this at all possible ?

So far, I've downloaded the ARM cross compiler from http://www.codesourcery.com and installed it on my Ubuntu 10.10 and compiled a simple "Hello world" app using:-

> arm-none-linux-gnueabi-g++ hello.c -o hello

I copy this onto the Vega sdcard, but when I try to run the app, I get:-

> chmod 755 hello

> ./hello

./hello: permission denied

I can see that the sdcard is mounted noexec, so I then tried it at /data:-

> cp /mnt/sdcard/hello /data

> cd /data

> chmod 755 hello

./hello: not found

So I tried an strace:-

# strace ./hello

execve("./hello", ["./hello"], [/* 11 vars */]) = -1 ENOENT (No such file or directory)

write(2, "strace: exec", 12strace: exec) = 12

write(2, ": ", 2: ) = 2

write(2, "No such file or directory", 25No such file or directory) = 25

write(2, "\n", 1

) = 1

SYS_248(0x1, 0x48, 0x1, 0x4483d60b, 0x28658 <unfinished ... exit status 1>

Still nothing ...

Has anyone else managed even a simple statically built app ?

Cheers
