object-files

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;external; end. Error Code: function a_function():Integer;cdecl; function b_function();Integer;cdecl;

I know .OBJ is the result of compiling a unit of compilation and .LIB is a static library that can be created from several .OBJ, but this difference seems to be only in the number of units of compilation. Is there any other difference? Is it the same or different file format? I have come to this question when wondering if the same static variable defined in two (or more) .LIBs is merged or not during linking into the final executable. For .OBJs the variables are merged. But is it the same in .LIBs? A .LIB file is a collection of .OBJ files concatenated together with an index. There should be

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 fileb.f90 mainfile.f90). Is there a reason (other than, maybe, Makefiles) that one method is preferred

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? 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 print_hello(); #endif /* __PRINT_HELLO__ */ print_hello.c #include <stdio.h> #include "print_hello.h" void

I followed the ways mentioned in Link object file to my project Eclipse CDR My main function is in cpp code and from that I wish to call a c-function. So for that I created the object file (.o) from the c-code using gcc -c -fpic mycode.c This gave me a ".o" file which I wanted to link to the cpp code. I created a header file with reference to http://www.parashift.com/c++-faq/include-c-hdrs-nonsystem.html Header file was declared as an extern in my cpp code. The header file contains to function from the c-code, that function was declared as an extern in header file. After doing this when I do

I'm trying to compile µcOSIII for my board (XMC4500 Relax Kit) but when I try to compile my files I get following output: 'Building target: XMC4500_uCOSIII.elf' 'Invoking: ARM-GCC C Linker' "C:\DAVE-3.1.10\ARM-GCC/bin/arm-none-eabi-gcc" -T"../XMC4500_uCOSIII.ld" -nostartfiles -L"C:\DAVE-3.1.10\eclipse\/../CMSIS/Infineon/Lib" -L"C:\DAVE-3.1.10\eclipse\/../Examples/Lib" -L"C:\DAVE-3.1.10\eclipse\/../emWin/Start/GUI" -Wl,-Map,"XMC4500_uCOSIII.map" -mcpu=cortex-m4 -mthumb -g3 -gdwarf-2 -o "XMC4500_uCOSIII.elf" "@makefile.rsp" Libraries/uCOS-III/Source/os_core.o: In function `OSIntExit': D:

This is really a linker / object-file question, but tagging with assembly since compilers never do this. (Although maybe they could!) Consider this function, where I want to handle one special case with a block of code that's in the same I-cache line as the function entry-point. To avoid jumping over it in the usual fast-path, is it safe (wrt. linking / shared libraries / other tools I haven't thought of) to put the code for it ahead of the function's global symbol? I know this is silly / overkill, see below. Mostly I was just curious. Regardless of whether this technique is useful for making

I'm working on a project from school, and we were given a .o and a corresponding .h file. We need to use several functions from the .o file in our .c program. Just placing it in the same directory doesn't work. I tried to look for something like this in the project properties, but no good. I keep getting ../code_files/Search.c:116: undefined reference to 'reportError' I'm using Eclipse (Juno) CDT, gcc MinGW under Windows 7 I know it's possible to include .a files, but I couldn't find any indication on how to include a .o file #include "ErrorHandle.h" is included in the main c file.
