Code compiles but different code is executed [message #1406335]

So I am not new to c++ programming but this has me thrown for a loop every single time. I make code changes to an existing Makefile project. I set up the project correctly. I then modify code in a shared library. It compiles and I debug the application so the application launches.

None of my code changes are hit. GDB recognizes the new lines of code but nothing I add is executed. For example, say there is a line such as:

DETAILED_MESSAGE("Read headers in " << dataFile) ;

which will print to the console:

[22:54:53]patModelSpec.cc:560 Read headers in /home/ben/Dropbox/Disertation/wtp_space/output_biogeme_test.dat

but when I change it to:

DETAILED_MESSAGE("Read headers in WIOEFJAOIWJEAFWAEI" << dataFile) ;

it will still only print
[22:54:53]patModelSpec.cc:560 Read headers in /home/ben/Dropbox/Disertation/wtp_space/output_biogeme_test.dat

That means to me that changes to an existing string are not recognized. I try to std::cout << "hello" << std::endl; and the debugger hits the code and does absolutely nothing.

I don't know why this is happening. The application builds. The code compiles. The debugger picks up the break points. The code gets hit. I see nothing changing when the application runs including all print statements and any code change I make. As a note though, if the syntax is wrong, it will underline it in red and say that "There was a problem, should I continue?" and regardless of how I answer, the same thing happens.

Can anyone please tell me what is going on? I really would love the help.

I'm not sure if I can help Ben, but just so I understand, do you have 1 or multiple C++ projects in Eclipse? Are you modifying them outside Eclipse? I've seen something like this before where the project needed to be refreshed in eclipse to get the source in-sync with the object code.
