It is normal that a Unix-like system has a "kernel compiler" always, for compiling the system's "kernel" (base operating system). But not the "development system" for making even very simple C applications like the "Hello World"... > configure: error: C compiler cannot create executables So you got this error... Never tried to compile & link a simple C program like "Hello World" ? Before trying to build something as big a the GCC compiler collection... https://www.programiz.com/c-programming/examples/print-sentence
