© Jeff Drobman2016-2019Software Tool Chain

v CompilersØ Compiled languages (C, C++, C#, VB)

² Compile completely: Translate HLL (.c, .h) into ASM (.asm)Ø Interpreted languages (Java, Pascal)

² Compile incompletely (“JIT”) to an “intermediate” language² “Pseudo” code is compiled at run time (slow)

v Assemblers² Translate ASM (.asm) into linkable machine code modules (“LM”)

v Linkers² Combine (“link”) LM modules into a single “executable” (.exe)² Resolve external references² Embed calls to dynamic “link libraries” or “frameworks” (.dll files)

v Debuggers

v SDK contains Compilers + API (Libraries) + IDEv IDE is a development environment w/debugger
