Extern keyword and unresolved external symbols!
I drew a little graph in paint that explains my problem: But it doesn't seem to show up when I use the <img> tag after posting? Here is a direct link: http://i44.tinypic.com/103gcbk.jpg ...

Are there general guidlines for solving undefined reference/unresolved symbol issues?
I'm having several "undefined reference" (during linkage) and "unresolved symbol" (during runtime after dlopen) issues where I work. It is quite a large makefile system. Are there general rules and guidelines for linking libraries and using compiler flags/options to evade these types of errors? ...
VSTS DB GDR - Why are references unresolved within the same database?
I am playing around with the Visual Studio Team Suite Database Edition GDR, and I've imported several of our databases. I have literally thousands of warnings, most of which are unresolved references. I understand when we don't have SchemaName.dbo.TableName for external references, but why would there be warnings (even errors) when the...

Problem in plug-in development: Eclipse 3.4 can't find a bundle that is definitively there!
Today I had a problem with my old Eclipse 3.4 installation and I had to re-download the entire package. However, I don't think that I got the exact package as before, and I'm having some problems. The problem can be summarized as follows: when developing a plug-in, I cannot resolve dependencies towards 'org.eclipse.jdt.ui'. When trying ...
Possible reasons for [ILINK32 Error] Error: Unresolved external '__fastcall System::TObject::NewInstance(System::TMetaClass *)' referenced from XXX.obj?
Can you suggest what factors can cause an C++ Builder's 2009 linker error "Unresolved external '__fastcall System::TObject::NewInstance(System::TMetaClass *)' referenced from XXX.obj"? We have a set of Delphi files (pas) and set of C++ Builder files (hpp and obj), which was generated from these pas files. Set of files is copied to anot...
Easy check for unresolved symbols in shared libraries?
I am writing a fairly large C++ shared-object library, and have run into a small issue that makes debugging a pain: If I define a function/method in a header file, and forget to create a stub for it (during development), since I am building as a shared object library rather than an executable, no errors appear at compile-time telling me...
Linking with Apache XML-Security causes unresolved references
I'm trying to build a project on Linux with GCC where one module (my own) require XML-Security (Apache's) as well. However, when linking, I get unresolved references to some functions that are in the XML-Security library. I'm attempting to link statically (or I think so, at least -- I've provided no extra parameters, and I'm using the .a...

Why are my resources suddenly unresolved in my Android project?
Eclipse is complaining about my Android project saying all my references to resources are unresolved, even though R.java does exist. For example: signin_btn=(Button)findViewById(R.id.signin_btn); signin_btn.setOnClickListener(this); I definately have signin_btn defined in my resources. Dont know why Eclipse is not seeing my R class any...
MSVC 2008 - Unresolved External errors with LIB but only with DLL, not with EXE project
I have a DLL that I am trying to link with a libjpeg LIB using MSVC 2008 that is generating Unresolved External Symbol errors for the libjpeg functions. I also have a test project that links with the exact same libjpeg library file and links without error and runs fine too. I have triple-checked my LIB path and dependent LIBS list se...
How to detect unresolved symbol when creating a library ?
Hello everyone, Under Solaris 10, I'm creating a library A.so that calls a function f() which is defined in library B.so. To compile the library A.so, I declare in my code f() as extern. Unfortunately, I "forgot" to declare in A's makefile that it has to link with B. However, "make A" causes no warning, no error, and the library A.so i...

Maven Multi Module Project breaking compile-time class resolution
Hi, I've been previously managing a 3-module project as 3 seperate maven projects. As this project has been moving forward, I decided I ought to take advantage of the dependency management of maven2 to streamline integration between these 3 evolving modules. I defined a super-project that deploys as POM. Some shared dependencies are de...
setup include path in eclipse CDT in mac os (headers from framework)
for example I need to include a header #include <OpenGL/glext.h> while it is actually a header file glext.h under OpenGL.framework/Headers/. Therefore it is no way to give eclipse a physical path about "OpenGL/glext.h", and I always get unresolved inclusion warning. I can still build and run them (with managed makefile project) but ...
C++ project compiles as static library but not dynamic (Visual Studio)
I'm a little new to c++ in visual studio, and I'm trying to compile a massive C++ project with Visual Studio. I've gone through and added all source and header files to my project and also updated all of the include paths in the project properties. If I have the type of project set to "Static Library (.Lib)" the project will compile wi...
