Why does a compiler need an operating system?

The compiler, like all applications, relies on the OS to load it into memory and start it executing.

Why is operating system system dependent?

Any operating system is at least depending on one piece of hardware: the CPU. There are different CPUs, each working differently and having a different “native language”. Since an OS is “just a program” which needs to run on the CPU, it must be written in the CPUs native language is thus dependent on it.

Is the compiler part of the OS?

Not all compiler systems separate the compiler from the linker — if it’s one program, than it would be OS-specific. However, there are OS/machine independent compilers: most notably Java (and other JVM-based languages, such as Scala or Groovy).

What is OS compiler?

In computing, a compiler is a computer program that translates computer code written in one programming language (the source language) into another language (the target language). A program that translates between high-level languages is usually called a source-to-source compiler or transpiler.

What are the advantages of a compiler?

Compilers have several advantages:

  • Compiled programs run quickly, since they have already been translated.
  • A compiled program can be supplied as an executable file. An executable file is a file that is ready to run.
  • Compilers optimise code. Optimised code can run quicker and take up less memory space.

What are the uses of a compiler?

compiler, computer software that translates (compiles) source code written in a high-level language (e.g., C++) into a set of machine-language instructions that can be understood by a digital computer’s CPU. Compilers are very large programs, with error-checking and other abilities.

What does a dependent system mean?

A dependent system of equations is when the same line is written in two different forms so that there are infinite solutions. These two situations occur when trying to solve for a system of equations.

What is OS independent operating system?

3. What exactly do we mean when we say that a program is OS-independent? It means that it has been written in a way, that it can be compiled (if compilation is necessary for the language used) or run without or just little modification on several operating systems and/or processor architectures.

Are compilers OS dependent?

Compilers as programs running on a computer are OS dependent like any other program.

Is compiler hardware dependent?

Compilers are hardware dependent, unless you are thinking of interpreters. Interpreted languages are not hardware dependent, because they run on top of an interpreter, and the interpreter is hardware dependent.

Is compiler dependent on OS?

What is the function of compilers and interpreters?

Both compilers and interpreters are used to convert a program written in a high-level language into machine code understood by computers.

Why are compilers hardware platform/architecture dependent?

Compilers as compilers hardware platform/architecture dependent because they generate code for specific hardware. Linkers which are part of the build chain of programs need to generate libraries and executables that work nicely with the loaders of a specific OS. Note that the object code generated by pure compilers does not have to be OS dependent.

Is the object code generated by pure compilers OS dependent?

What is the difference between assembler and compiler?

The assembler the links code and generates binary code which the hardware can execute. For more information on this topic look for more information on co-generation. Consider Java which is not platform-dependent. Java compilers generate Java bytecode which is run on the Java virtual machine (JVM).

Why do linklinkers need to be OS dependent?

Linkers which are part of the build chain of programs need to generate libraries and executables that work nicely with the loaders of a specific OS. Note that the object code generated by pure compilers does not have to be OS dependent. Compilers as programs running on a computer are OS dependent like any other program.
