What is the binary compatibility of programs under Linux?

Question

linux

Then suddenly a question arose, can anyone help. I use RHEL and have very exotic processors (32-core xeons, all that). Let's imagine that I'm on a ship, and I want to write on a laptop under Hyper-V. The question is: can I, for example, install CentOS (under Hyper-V) and get binary (!) compatibility, given that the instruction set of the server Xeon and the laptop i7 are still different?
Nb: Intel C++ Compiler is used for development.

Answer 1

In general, there is such a thing as cross-compilation. It is necessary to look at what architectures your compiler supports.

Answer 2

32-core xeons, all that

x86_64 processor architecture, non-standard instruction set which you will hardly use, or rather, your compiler will use something else without checking whether it exists.

Answer 3

Binary compatibility depends more on libraries and the environment than on the processor
in gcc there is an option mtune - non-strict optimization
if you build for the average x86_64 and do not be zealous with SSE and the like - it will work everywhere
, but threads are your job, not the compiler :-)

Answer 4

Cross compilers for all supported platforms. Obviously, at least GLIBC and GLIBCXX you will have to drag from the target platform to your sysroot, it's easy
