I'm using OS X 10.7.3. I've been playing with the boost headers for a while now and i wanted to move onto using the Boost.Filesystem lib however it keeps throwing this message at me:

i get this when i try to compile using this:
g++ -o test main.cpp -I -l/opt/local/include ~/boost/libs/libboost_filesystem.a
So i went back to the boost.org tutorials and tried out the regex example. It worked perfectly using this:
g++ -o test main.cpp -I -l/opt/local/include ~/boost/libs/libboost_regex.a
try
g++ -o test main.cpp -I/opt/local/include -L/opt/local/lib -lboost_filesystem
Your compiler flags seem a bit off. Generally, the following hold:
-I // Sets the path for the relevant header files
-L // Sets the path where your libraries reside
-l // specifies the library you want to link against.
So, if you have a library called mylib in ~/libs/ and need to use header files located in ~/include, you'd pass
-I ~/include -L ~/libs -lmylib
as flags to the compiler.

Thanks
It could be related with wrong or corrupted version of installed ProtoBuf, because if protobuf is installed and has version more than 3.0, than gRPC building system uses system's protobuf, instread thrird-party-protobuf from subrepo. Try to remove or fix protobuf in your system.
UPDATE:
For new issues try to run "readelf -s lib???.so" for each grpc and protobuf library, and try to find this symbols in libraries. If in some library is specified "UND", than it is wrong library.
Second things that you should do, run "file lib???.so" for each grpc and protobuf library for check binary type: x86_64 or not.
I have version 2.6 of Google protobuffers installed via macports and gcc 4.8 and, when I compile my code (with the -lprotobuf flag), get the following link error:

My LD_LIBRARY_PATH is correct (otherwise the -lprotobuf flag would not be recognised)
protoc --version returns 2.6.1

I've checked that the library is compiled for 64 bits.
Non-fat file: /opt/local/lib/libprotobuf.a is architecture: x86_64
Any ideas where I am going wrong?
I'm trying to get OpenCV to work on my computer - for simple programs I can get it to work but for this certain program I'm unable to. The error I am getting is as follow:

I know that this error is not in the code of qDPC.cpp since it can compile on my friend's Ubuntu (I'm working on a Mac) - so I was wondering if there's something wrong with my OpenCV? I've read online online that it might be a linker problem but can't for the life of me figure this problem out. The version of OpenCV I have is 2.4.11, and the version my friend is able to compile with is 2.4.9.
All help is appreciated!

The answer is there: https://mathematica.stackexchange.com/questions/34692/mathlink-linking-error-after-os-x-10-9-mavericks-upgrade
There are two implementations of the standard C++ library available on OS X: libstdc++ and libc++. They are not binary compatible and libMLi3 requires libstdc++.
On 10.8 and earlier libstdc++ is chosen by default, on 10.9 libc++ is chosen by default. To ensure compatibility with libMLi3, we need to choose libstdc++ manually.
To do this, add -stdlib=libstdc++ to the linking command.
Related post: Compiling with Clang using Libc++ undefined references
Edit: After some investigations it seems there is a link between the -mmacosx-version-min and the choice of the default libstd. If min version < 10.9, then the default libstd is equal to libstdc++, else to libc++. The long term solution is clearly to use -stdlib=libc++
Those suggestions did not work for me with Mac El capitan. If you have similar issues after upgrading to El Capitan, just run
xcode-select --install
before trying to compile

There are many other posts on "undefined symbols for such&such architecture," and I have attempted to use those suggestions to successfully compile.
I think the problem may arise from the header file, variant.h. In the API from which the source code came there was a corresponding variant.cpp file that defined the functions, which were only declared in variant.h. I moved those definitions into variant.h. Any thoughts on what I may be missing? I can provide the header if need be, but it is long. Thanks.
