Compiling for only one platform?

Question

Debian

Do I need to recompile a c++ project from Ubuntu to Debain? (The hardware is the same)

Answer 1

Generally - yes, it is better to recompile.
But this does not depend on the name of the distribution, but on the versions of specific libraries on which the project depends. Some version differences allow binary compatibility of dependent packages, some do not. Therefore, for each (compiled) binary package, the range of versions of the libraries on which it depends is always clearly stated. This means that the package has been tested on this range, works correctly and can be ported to any debian-based distribution provided that the versions of the libraries match, otherwise it will not install.

Answer 2

gcc ...-static... set the linker flag when compiling. Get a big binary with no dependencies if you're lucky.

Answer 3

Depends on the libraries the project is linked against. If we get lucky.

Answer 4

No, but there are many nuances. The most important are, of course, the bit depth and the presence of dependencies. The ldd command will help you determine the dependencies.

Answer 5

Not necessary
