However, when compiling almost finished, Xcode returned a bunch of "Apple Mach-O Linker Error", saying, for example,Undefined symbols for architecture x86_64:"_MPI_Abort", referenced from:MPI::Comm::Abort(int) in hybevaluate.oMPI::Comm::Abort(int) in hybretintfun.oMPI::Comm::Abort(int) in hybint.oMPI::Comm::Abort(int) in hybmatrix_ft.oMPI::Comm::Abort(int) in hybupdates.oMPI::Comm::Abort(int) in hybmain.oMPI::Comm::Abort(int) in hybfun.oand a lot of similar errors have to do with the MPI functions and other ALPS functions such as hdf5, ngs, etc. It seems the compiler can correctly find where the dylib files are, and so I am not sure what else can be wrong...I hope this question is less dumber than my previous one...Thanks.Sincerely,Leo (Fang Yao-Lung)Duke Physics
