[Darshan-users] Darshan undefined compilation error

I have been trying the mpicxx -profile=/path/to/mpicxx-cxx.conf option
since I have gotten further with this method, but here is the output for

when using mpicxx.darshan method:

g++ -o binary *.o darshan/simple.cc
-L/home/adhaider/apps/mpich_install/lib -lmpicxx -Wl,-rpath
-Wl,/home/adhaider/apps/mpich_install/lib -Wl, --enable-new-dtags -lmpi

* notice the above doesn't even have the darshan libs.

Now when using mpicxx -profile=/path/to/conf

g++ -o binary *.o darshan/simple.cc
-L/home/adhaider/apps/mpich_install/lib -lmpicxx -lmpicxx
-L/home/adhaider/apps/darshan_install/lib -ldarshan -lz
-Wl,-rpath -Wl,/home/adhaider/apps/mpich_install/lib -Wl,--enable-new-dtags
-lmpi -L/home/adhaider/apps/darshan_install/lib -Wl,--start-group -ldarshan
-ldarshan-stubs -Wl,--end-group -lz -lrt -lpthread

Thanks in advance!
