I installed apt-build on Ubuntu, it is a program that compiles and installs programs. It compiles optimally for the user processor and this makes programs run quickly.
But I thought what if I change my processor in the future, programs compiled for the old processor will present problems? If yes, then I have to compile again?
Please someone who use apt-build help me.
On installing apt-build, you set the parameters for optimization. You can check what this are currently by running:
cat /etc/apt/apt-build.conf
Which in my case gives:
build-dir = /var/cache/apt-build/build
repository-dir = /var/cache/apt-build/repository
Olevel = -O2
mtune = -mtune=i586
options = " "
make_options = " -j4"
So you can see mine is optimized of i586 architecture, as this computer has a Intel i5 processor (I think i586 is right for this type - seems to work).
It also depends on what you set here:
So if your apt-build settings are set to Strong, they are less likely to work.
If you want to change the settings you set, you can do that simply by running:
sudo dpkg-reconfigure apt-build
So as long as your processor is better than the old one, it might be fine...
