Test EDK program mostly compiles so far
[EDIT]: It is now working! See this commit for how we did it.
While we were working on our homework, I decided to try writing a test program that would simply. A lot of the code is just copied from /opt/EmotivResearch_2.0.0.20/doc/examples_Qt/example1/main.cpp. The Makefile for the program was written from scratch. Here were the instructions I ran to compile it.
make clean env LD_LIBRARY_PATH=/opt/EmotivResearch_2.0.0.20/lib make env LD_LIBRARY_PATH=/opt/EmotivResearch_2.0.0.20/lib ./test-bin
Running the second of the former commands produces the following output:
g++ -g -I/opt/EmotivResearch_2.0.0.20/include -L/opt/EmotivResearch_2.0.0.20/lib -o test-bin main.c -L/opt/intel/composer_xe_2015.0.090/compiler/lib/intel64 -L/opt/intel/composer_xe_2015.0.090/mkl/lib/intel64 -lcryptopp_64 -ludev -lmkl_rt -liomp5 -lboost_serialization -lboost_system -lboost_regex -lboost_filesystem -lpng12 -lQtCore -lQtGui -ledk_utils_linux -ledk /usr/bin/ld: warning: libboost_serialization.so.1.51.0, needed by /opt/EmotivResearch_2.0.0.20/lib/libedk.so, may conflict with libboost_serialization.so.1.56.0 /usr/bin/ld: warning: libboost_system.so.1.51.0, needed by /opt/EmotivResearch_2.0.0.20/lib/libedk.so, may conflict with libboost_system.so.1.56.0 /usr/bin/ld: warning: libboost_regex.so.1.51.0, needed by /opt/EmotivResearch_2.0.0.20/lib/libedk.so, may conflict with libboost_regex.so.1.56.0 /usr/bin/ld: warning: libboost_filesystem.so.1.51.0, needed by /opt/EmotivResearch_2.0.0.20/lib/libedk.so, may conflict with libboost_filesystem.so.1.56.0
Running the second of the former commands with -lboost_md5 added to the list of link flags produces a peculiar error even though the *.so is in one of the -L'd directories
g++ -g -I/opt/EmotivResearch_2.0.0.20/include -L/opt/EmotivResearch_2.0.0.20/lib -o test-bin main.c -L/opt/intel/composer_xe_2015.0.090/compiler/lib/intel64 -L/opt/intel/composer_xe_2015.0.090/mkl/lib/intel64 -lcryptopp_64 -ludev -lmkl_rt -liomp5 -lboost_serialization -lboost_system -lboost_md5 -lboost_regex -lboost_filesystem -lpng12 -lQtCore -lQtGui -ledk_utils_linux -ledk /usr/bin/ld: cannot find -lboost_md5 collect2: error: ld returned 1 exit status Makefile:7: recipe for target 'test-bin' failed make: *** [test-bin] Error 1
However, ls -l /opt/EmotivResearch_2.0.0.20/lib shows the following output:

I initially shrugged off the output warnings that ld gave me until I tried connecting the test program to the EmoComposer. It crashed because it couldn't find the reference to libboost_md5

(gdb) quit
A debugging session is active.
Inferior 1 [process 7092] will be killed.
Quit anyway? (y or n) y
At least we can still write a rudimentary AI while trying to figure out why g++ isn't picking up the libboost_md5 from the Emotiv SDK tarball.
