Linker Command Failed With Exit Code 2

When exploring linker commandfailedwithexitcode 2, it's essential to consider various aspects and implications. c++ - What do linkers do? The linker works almost like a word processor's copy and paste. It "copies" out all the necessary functions that your program references and creates a single executable.

Sometimes other libraries that are copied out are dependent on yet other OBJ or library files. Moreover, sometimes a linker has to get pretty recursive to do its job. Equally important, how does the compilation/linking process work?

It's important to note that, linking The linker is what produces the final compilation output from the object files the compiler produced. This output can be either a shared (or dynamic) library (and while the name is similar, they haven't got much in common with static libraries mentioned earlier) or an executable. What is compiler, linker, loader?

I wanted to know in depth meaning and working of compiler, linker and loader. Moreover, with reference to any language preferably c++. What are the differences between a compiler and a linker?.

30 A compiler generates object code files (machine language) from source code. A linker combines these object code files into an executable. Many IDEs invoke them in succession, so you never actually see the linker at work. It's important to note that, some languages/compilers do not have a distinct linker and linking is done by the compiler as part of its work. linker - C header files and compilation/linking - Stack Overflow.

The linker knows where a symbol is defined because object files also contain the symbols defined in the translation unit. If you want more details about how linkers work I suggest you search for information about that in your favorite search engine, as it's a much to broad subject to answer here (especially in comments). c - How to write a linker - Stack Overflow. This perspective suggests that, i need to write a linker, and am stuck.

The object format is a custom one, designed around the byte code interpreter, so I cant really use any existing linkers. My biggest hurdle is how to organize the object code to output the linked binary. Dynamic linking is not necessary, at this time. Similarly, i need to get static linking working first.

error: linker `link.exe` not found while using VS code. linker - Limiting visibility of symbols when linking shared libraries .... Another key aspect involves, 66 Some platforms mandate that you provide a list of a shared library's external symbols to the linker. Furthermore, however, on most unixish systems that's not necessary: all non-static symbols will be available by default.

My understanding is that the GNU toolchain can optionally restrict visibility just to symbols explicitly declared.
