Hello, Folks
Sorry to bug you guys with this but I am sure there are tons of people have encountered this before, I am creating a MPI program with MPICH-2 and gfortran on Windows 8 64 with MinGW, but for some reason the MPICH-2 can't be linked and errors are:
hello_mpi.o:hello_mpi.f90:(.text+0x10): undefined reference to `mpi_init_' hello_mpi.o:hello_mpi.f90:(.text+0x2a): undefined reference to `mpi_comm_size_' hello_mpi.o:hello_mpi.f90:(.text+0x44): undefined reference to `mpi_comm_rank_' hello_mpi.o:hello_mpi.f90:(.text+0x54): undefined reference to `mpi_wtime_' hello_mpi.o:hello_mpi.f90:(.text+0x6bd): undefined reference to `mpi_wtime_' hello_mpi.o:hello_mpi.f90:(.text+0x7f7): undefined reference to `mpi_finalize_' c:/users/<myid>/program_files/mingw/bin/../lib/gcc/mingw32/4.8.1/../../../../mingw32/bin/ld.exe: C:\Users\<myid>\AppData\L ocal\Temp\cckYDcnb.o: bad reloc address 0x20 in section `.eh_frame' c:/users/<myid>/program_files/mingw/bin/../lib/gcc/mingw32/4.8.1/../../../../mingw32/bin/ld.exe: final link failed: Inval id operation collect2.exe: error: ld returned 1 exit status
This is just a "hello world" program and I followed the instructions in the README.winbin.rtf file
"
2) add –I…mpich2\include
3) add –L…mpich2\lib
"
Some people believe that the "-lmpi" option should be used at the very end of command, I did that but doesn't help.
I even tried compiling without any makefile but just a single command like:
gfortran.exe -I"C:\Program Files\MPICH2\include" hello_mpi.f90 -L"C:\Program Files\MPICH2\lib" -lmpi
But still it doesn't work for me.
Did any of you guys have encountered this before?
I really look forward your response, any inputs are highly appreciated!!!
Thank you so much!
Best Regard
NOTE:
Here is my simple makefile:
F90 = gfortran MPI_DIR = /c/Program\ Files/MPICH2 MPI_LIB_DIR = $(MPI_DIR)/lib MPI_LIB_INCLUDE = $(MPI_DIR)/include MPI_LIB = -L$(MPI_LIB_DIR) -lmpi MPI_INCLUDE = -I$(MPI_LIB_INCLUDE) SRC = hello_mpi.f90 OBJ = $(SRC:.f90=.o) EXEC = hello $(EXEC): $(OBJ) $(F90) -o $(EXEC) $(OBJ) $(MPI_LIB) $(OBJ) : $(SRC) $(F90) $(MPI_INCLUDE) -c $< clean: rm *.o _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
