Also the generated executable will automatically use the new ld-linux-xxxxx program loader which will automatically find the new libc. I want to put the whole toolchain in some separate directory, and not to influence any existing system files. I also want to build gcc with –sys-root so that when using the gcc, I don’t need to specify -I/some/directory/include and -L/some/directory/lib or whatever other parameters.
You could even do some ‘house cleaning’ between reboots, say make a backup, email a notice etc It’s all up to you, and what you are capable of batch script programming wise. If Qemu runs ‘normally’ you can even set it up into a batch file loop that calls Qemu over and over as needed between reboots.
This tells us that the file is built for an ARM processor and not for your host system. You’re now all set to cross compile for the Pi. Copy that file to your Pi, set the execute and owner permission bits, execute it, and it will generate the “Hello World” message.
, the RPi running raspbian based on wheezy). Both targets are running wheezy (i. 13 and it is not easy to find an armhf toolchain that ships with glibc 2. The snag I ran into was attempting to compile an app that could run on both the RPi and the BeagleBone Black. They are still stuck on glibc 2.
It’s not the end of the world but UPNP doesn’t work in nat-nat scenarios (thankfully) but the blasted game doesn’t mention when setting up a network game, oh by the way you’ll need to NAT TCP 7777. And if you have an Apple airport network, a teenager that needs to have ‘cut off times’ and sits 2 levels of NAT in, you’ll have to forward TCP 7777 all the way to their computer.
/usr/local comes to mind). If you can’t/won’t, the best bet is to get the pieces as source RPMs for CentOS and Fedora, unpack them and fix up the CentOS by pilfering the sources and patches from Fedora, take care it doesn’t overrule the system packages, correct versions and fix to install elsewhere (don’t mess up your system too much. The pieces are at least binutils, gcc.
Once Qemu is operational you can disconnect the screen session and it’ll remain operational. You will need to run screen, then launch Qemu from within screen, then it’ll prompt for the password for each disk drive. It’s been around for a long long while, and every Linux distro should have it available. Doing so in a script would require you to store the password locally, and defeats the whole point of encrypted storage. If you did choose to encrypt your disks, you will need the program ‘screen’.
Also I’d HIGHLY recommend NEVER EVER installing a compiler on the VPS. The same goes for things like firewalls. Again pick something you are most comfortable with, and try to stick with that. Also setup a VM at home with the same OS, same cpu, same flavor *WITH* compiler, so that way you can check updates at home, to make sure things work, and of course compile things like Qemu for your environment without worrying about things that are either incredibly stale in packages, or just not there at all. Pick a distro that you are somewhat comfortable with. If someone does get onto your system, handing them a compiler is like a loaded gun. At least make it more. Personally I went with Debian in my VPS’s as that is what I’m the most comfortable with. ) and CentOS, the RedHat ‘free’ clone. Another thing to keep in mind is that with your own VPS you will be the one required to keep it up to date. The majority of OS’s available are Debian, various Debian forks (Unbutu.
8% of a 3Ghz CPU is more than enough for stuff that ran comfortably on a 16Mhz machine back in the day. This gives me two named instances, and will automatically limit my Qemu to only 8% of the host CPU that way I don’t get kicked for being a CPU hog.
Tools are executed, usually as cross compilers, and can be, in our case, any platform that supports Eclipse, for example Windows, macOS, GNU/Linux, etc. The build plug-in is highly configurable in terms of executable names and location, so you can use any 32/64-bits ARM GNU toolchain you prefer, but.
