Why Compile to an Object File First?

问题 In the last year I've started programming in Fortran working at a research university. Most of my prior experience is in web languages like PHP or old ASP, so I'm a newbie to compile statements . I have two different code I'm modifying. One has an explicit statement creating .o files from modules (e.g. gfortran -c filea.f90) before creating the executable. Another are creating the executable file directly (sometimes creating .mod files, but no .o files, e.g. gfortran -o executable filea.f90

Is it possible to import/run object files in eclipse?

问题 Our professor made available object files of a previous assignment that I wasn't able to complete. This previous assignment is required for completing/testing the current assignment. Would it be possible somehow for me to import them into eclipse or somehow make my project work with those object files? 回答1: Let's say you have object file print_hello.a and a header print_hello.h . To be more precise let's create print_hello.a : print_hello.h #ifndef __PRINT_HELLO_ #define __PRINT_HELLO_ void

问题 I am new to delphi. I was trying to add C Object files in my Delphi project and link them directly since Delphi Supports C Object Linking. I got it working when i link a single Object file. But when i try to link multiple object files, i am getting error 'Unsatisfied forward or external declaration'. I have tried this in Delphi 2007 as well as XE.So what am i doing wrong here? Working Code: function a_function():Integer;cdecl; implementation {$Link 'a.obj'} function a_function():Integer;cdecl

What's an object file in C?

I am reading about libraries in C but I have not yet found an explanation on what an object file is. What's the real difference between any other compiled file and an object file? I would be glad if someone could explain in human language. An object file is the real output from the compilation phase. It's mostly machine code, but has info that allows a linker to see what symbols are in it as well as symbols it requires in order to work. (For reference, "symbols" are basically names of global objects, functions, etc.) A linker takes all these object files and combines them to form one

combine two GCC compiled .o object files into a third .o file

问题 How does one combine two GCC compiled .o object files into a third .o file? $ gcc -c a.c -o a.o $ gcc -c b.c -o b.o $ ??? a.o b.o -o c.o $ gcc c.o other.o -o executable If you have access to the source files the -combine GCC flag will merge the source files before compilation: $ gcc -c -combine a.c b.c -o c.o However this only works for source files, and GCC does not accept .o files as input for this command. Normally, linking .o files does not work properly, as you cannot use the output of
