What version of GCC should I use?
The kernel build requirements are quite conservative: for kernel 4.18, GCC 3.2 and binutils 2.20 are sufficient. Thus your distribution’s compiler should work fine. In practice pretty much any version of GCC will do, although one can sometimes run into problems with versions of GCC which are too new.

GCC has always performed well as a standard compiler in the open source community. However, Apple Inc. has its own requirements for compilation tools. On the one hand, Apple Inc. added many new features for the Objective-C language (or even, later, the C language).
Should I use the latest gcc?
I have done it quite often, with almost all gcc versions starting from 4, for the improved C++ standards compliance, and, quite often, gains in compilation time and improvements on the optimizer. In general, it is a good idea to use the latest g++ compiler.

Is LLVM better than GCC?
While LLVM and GCC both support a wide variety languages and libraries, they are licensed and developed differently. LLVM libraries are licensed more liberally and GCC has more restrictions for its reuse. When it comes to performance differences, GCC has been considered superior in the past.
Is LLVM faster than GCC?
Only when LLVM was compiled with PGO to build 32-bit ARM was it faster at compiling the Linux kernel than GCC. With the upstream Clang compiler building the upstream kernel compiler for x86_64 and AArch64 (and most recently i686), the LLVM developers will be looking more closely at build times moving ahead.
Is there a bug in the GCC compiler?
An error that occurs only some of the times a certain file is compiled, such that retrying a sufficient number of times results in a successful compilation; this is a symptom of a hardware problem, not of a compiler bug (sorry)
Is there a wrong version of GCC in Ubuntu?
With that in mind, if you manually altered the symlink between /usr/bin/gcc and the version used in your version of Ubuntu, future DKMS-built modules might use the wrong gcc version. If you just want to build things with a different version of gcc, that’s easy enough, even with makescripts.
Why is my Raspberry Pi not running GCC?
When you try to run a command like gcc –version your system searches the paths inside the environment PATH variable (windows has one too) to find that program. That variable has the path /usr/bin inside it, so it checks if there is a programmed called gcc on /usr/bin/gcc.
