Executing beaglebone's programs by qemu-user-static

[Otacilio]

Hi

I would like to ask for some help. I own a  beaglebone black and an 
amd64 machine. Both running FreeBSD 11.1. I want to write programs to 
the beaglebone by running codeblocks on the AMD64 machine and also to 
execute the beaglebone's C compiler. Firstly, I exported the beaglebone 
black / file system using NFS and mounted it on the AMD64 machine in the 
/usr/bbb folder. Then I installed qemu-user-static and added the entry 
in /etc/rc.conf to execute the beaglebone's ARM programs through qemu. 
For example, when I run /usr/bbb/usr/bin/cc the beaglebone's C compiler 
is executed on the amd64 machine through qemu. But, as far as I 
understand the C compiler of the beaglebone searches for the library 
files from the /usr/lib and /usr/local/lib folders and not 
/usr/bbb/usr/lib and /usr/bbb/usr/local/lib folders, where the port 
libraries that are installed on the beaglebone are in fact. I thought of 
modifying the qemu code to add a chroot call after qemu-arm-static loads 
the beaglebone's application, but the qemu would need to execute as root 
for this to happen. Is there any way to turn the qemu process restricted 
to the /usr/bbb folder after loading the beaglebone application without 
the qemu running as a root? So far I'm thinking that perhaps I'll need 
to add something like a dir base on qemu to do that, so any systems that 
call or access a file or directory always start from that base folder 
(/usr/bbb).

Faithfully,
