I am trying to do my assignment for data structures class. The question is 1) Compile with UNIT_TEST defined and then run with -d yes to see the time it takes in seconds. Report that time in submission box along with the time you found when testing Selection Sort. Which is faster?
i am having trouble with understanding, what i am doing wrong. I am getting this error :

You've fallen victim to ADL "argument dependent lookup".
You should go look it up, because there are good explanations out there.
Basically, your operator >> should be in the same namespace as your rec_t.
But it's not - rec_t is in namespace std (since it's really std::tuple<int, std::string>), and operator >> is in the global namespace.
I'm having problems compiling a program called SDPB by following these instructions. To summarize, I'm installing a program that requires Boost, GMP, and OpenMP on Mac OS X Yosemite. All the individual pieces of code compile but when its time to link, I get Undefined symbols for architecture x86_64.
My question is basically identical to this question. However, I can't get the answers there to work for me. I still get the same error.
After more searching, I saw that people with similar questions were getting answers pointing to a conflict between clang and gcc. More specifically, there are issues with mixing the libraries libstdc++ and libc++.
Therefore, I made sure to recompile both Boost and GMP with gcc so that everything would be built using libstdc++. That didn't help. I then downloaded an implementation of clang that was compatible with OpenMP and tried to build everything using just libc++. That also didn't work. I then tried all sorts of permutations using clang with the -stdlib=libstdc++ flag and so on. Nothing seems to work. The details of the errors seemed to change a bit with the various permuations. I'll post a few snippets below. Of course, I always used the updated makefile to compile SDPB and I always configured GMP with the --enable-cxx flag as the answers linked above said to do.
Here, is a snippet of the error I received while compiling SDPB with gcc after I compiled GMP and Boost with gcc as well.

If anyone can help it would be much appreciated.
The Mac OS X Installation instructions have been updated and everything works now if I just blindly follow them to the letter.

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I've set Build Active Architectures Only to No in my build settings, but it still happens. What do I need to do to get OpenCV working? I'm using XCode 5, targeting iOS7.
I've already added -lstdc++ to linker flags and switch the C++ compiler to libstdc++, as-per this answer.
I have tried compiling OpenCV from source too but that yields the same error.
It's the same regardless of whether I have iOS6 or 7 as the deployment target.
Two things you should check:
You're attempting to use the C++ portions of OpenCV but Xcode/clang are very literal. If the file you're linking with is a .m it'll treat it as an Objective-C. Instead we want to treat it as an Objective-C++ file by either renaming the extension to .mm or by bringing up the file's properties in the right side bar and selecting Objective-C++ Source for the Type.
ALAssetsLibrary is defined in AssetsLibrary.framework, please add it to your Link Binary With Libraries step for your project.
Not sure if any had this problem or similar but if you have some help would be appreciated.
I have setup postgresql in the following location and set the link path to /usr/local/pgsql-9.0. Also setup the libpqxx in the /usr/local/lib
But I am guessing the error says that it cant find the postgresql anywhere. Is that correct ?
