c++ - How does the compilation linking process work? - Stack Overflow A linker is something that allows blocks of code to be compiled separately This can speed up the overall process of building code, and allows some flexibility with how the blocks are later used, in other words they can be relocated in memory, for example adding 1000 to every address to scoot the block up by 1000 address cells
What is compiler, linker, loader? - Stack Overflow Linker: Utility program which takes one or more compiled object files and combines them into an executable file or another object file Loader: loads the executable code into memory ,creates the program and data stack , initializes the registers and starts the code running
linker - Why does the order in which libraries are linked sometimes . . . The linker daemon is like a spaghetti colander, a bunch of symbols arrive at the colander walls and poke through the holes, and the linker must track all symbols and connect together all the symbols by address linkage If it misses some, the program will crash
What are the differences between a compiler and a linker? +1 good explanation Note that on most OS, there are actually two linkers involved: The linker that runs after compilation and produces the executable file (usually just called "linker"), and the linker that links in dynamically loaded libraries (aka so or dll) at execution time (usually called "dynamic linker") –
linker - Understanding the linkerscript for an ARM Cortex-M . . . To combine all text section of each translation unit the linker script provides some specific commands for the same This is the same for the data section as well After combining all the object files the final executable is ready to use
Access symbols defined in the linker script by application Therefore there might be a discrepancy between the name of a variable as it is used in source code and the name of the same variable as it is defined in a linker script For example in C a linker script variable might be referred to as: extern int foo; But in the linker script it might be defined as: _foo = 1000;
CMake: use a custom linker - Stack Overflow There are also both CMAKE_MODULE_LINKER_FLAGS and CMAKE_STATIC_LINKER_FLAGS, for completeness' sake And then of course potentially separate CMAKE_SHARED_LINKER_FLAGS_DEBUG, CMAKE_SHARED_LINKER_FLAGS_RELEASE, etc though I don't know what possible advantage there would be to modifying the linker for only some configurations –
Linker Script - Placing a section at the end of a memory region Now I build and link the rest of the program, and include the object file among the linker's input gcc metadata o main o -o Program elf -T linkerscript ld The linker reads the section metadata from the object file, and I can reference its size in the linker script
