real module system” Safety: - A toolchain should try its best to diagnose ODR violations e.g. linker errors for duplicate definitions, mismatching types Speed: - Matching a function call to its definition implementation freedom to enforce ownership - Throughout the entire toolchain, from parser to linker - MSVC implements a 'strong ownership' model. - Hope: More C++ toolsets offer this lib_m2(); int main() { if (lib_m1() != 42) return 1; if (lib_m2() != 1337) return 1; } ## Linker error: duplicate definition for exported symbols 'f()', needed by 'lib_m1()' and

Remark Take care that the object file you’re linking is in a format the linker understands. Which format this is, depends on the platform you’re on. Typing ld or ld -help on the files and options can be passed to the linker using the $ -k $ command line option. More than one of these options can be used, and they will be passed to the linker, in the order that they were specified
