Hello, I am getting a linked error when I changed file name to cpp. 1>main.obj : error LNK2019: unresolved external symbol "void __cdecl func_name(double * *,int,int,int,double * *,double * *,double * *,double * *)" I am using objects in my new code but this function which was there earlier is triggering this error.How do I handle it? Someone please let me know.

I have Clipper Compiler Ver 5.0, also an older version. I used the earlier version along with dBase III+. I still have both but cannot remember the command to compile the PRG files from dBase III+. I look for and OBJ file after typing Clipper <mymainprgfile>. I don't know if I'm missing a switch or something. When the compile has completed I would use PLINK86 <mymainprgfile>. I am not generating and EXE file like I used to. Does anyone have the documentation the from or what commands I need to compile and link using Clipper from Nantucket?

Hey everyone, I need some major help. I was going to get some development time in on one of my projects when I found that my installation of VS2008 Pro no longer wanted to compile any projects. I have tried making empty problems with just the int main(), nothing else added or included, but I still get unresolved linker errors. I have tried uninstalling everything related to VS2008 including .Net Framework 3.5.

In my program that uses separate compilation, the only problem I have left is a linker error. To see if it was just a syntax error somewhere obscure, I made a simple "hello world" program that uses separate compilation. I get the same error. The code is below. If someone knows what is wrong, that would be awesome if they could help. The header file: [CODE] //file name: Hello.h #ifndef HELLO_H #define HELLO_H #include <iostream> using namespace std; class Hello { public: Hello(int x); }; #endif //HELLO_H[/CODE] The implementation file: [CODE] //file name: Hello.cpp #include <iostream> #include "Hello.h" using namespace …

Well, I've been Googling for at least 30 minutes, and looking through past posts about this, but just can't seem to find an answer that works. Basically, I've got a component class that has a single method I'm trying to test out. The entity class has a private array of these components (actually, it's an array of void*, but I cast to the appropriate type when getting the component from the array). So when I call the method it looks like this: [code]((Component*)myEntity.getComponent(Base))->testFunction();[/code] This is the error I'm getting: 1>main.obj : error LNK2019: unresolved external symbol "public: __thiscall GE::Component::Component(void)" (??0Component@GE@@QAE@XZ) …

Hi all, So, I'm a real newbie at this, and I don't even know where to start really. I'd appreciate some help. I've downloaded Allegro 4.9 onto my computer (running Windows Vista), and I want to use it with Code::Blocks IDE. I've tried many a google search, but none of the tutorials seem to work properly. I've heard that you need to compile the library before you can link it, but I don't know how to do this either. (I've never before needed to download a library past the standard ones...)

I'm trying to compile an executable (ELF file) that does not use a dynamic loader. I built a cross compiler that compiles mips from linux to be used on a simulator I made. I asserted the flag -static-libgcc on compilation of my hello.cpp file (hello world program). Apparently this is not enough though. Because there is still a segment in my executable which contains the name/path of the dynamic loader. What flags do I use to generate an executable which contains EVERYTHING needed to be run? Do I need to rebuild my cross compiler? Is there a good resource describing …

I'm a bit confused about the executable offset in ELF files. Do you know what the difference between an address and an offset is in this context? It seems obvious but if you look at the 2 sections I bolded, sometimes the offset is something like : 00400164 000164 which is obviously just the offset in memory starting from 400000. Other times the offset doesn't match the address offset : 1000018c 010190. And sometimes the address and offset match with an additional offset of 0x10000 : 10000000 010000. Is there something I'm missing having to do with dynamic linking? How …

In a nutshell I am trying to write a program that will connect to a database, query several tables for various sets of data that will then be transformed into XML that is stored into a file on the local hard disk. My first thought process to solve this problem was to create classes that would be used to contain one row of data returned for each result set. I would create a base class that would define the common behavior between each derived class, while the derived classes would handle anything that is specific to the type of result …
