[mpich-discuss] function declaration conflicts in mpicxx.h

[Rajeev Thakur]

Try compiling the C++ example in the examples/cxx directory using
mpicxx. Make sure you use the mpicxx from the installed version of
MPICH2.

Hi all,

  I am new to MPI programming, and stacking in a conflict problem during
compiling. Declarations of function MPI::Init(int&, char**&) and
MPI::Init(), which are in mpicxx.h, conflict when my codes include
mpicxx.h. The following is the compile command:

  "g++  -I/home/zincum/apps/mpich2/include -I.
-I/home/zincum/apps/NF+GrACE/GrACE/include
-I/home/zincum/apps/HDF4/include
-I/home/zincum/apps/NF+GrACE/GrACE/packages/vampire/include
-DBEOWULF_ABSOFT -DWant_c_files  -DANSI_HEADERS  -g -c CommServer.cpp"

  Other compilers, such as gcc, mpicc, mpiCC, mpicxx, have been tried,
but none works.

  Here is the detail error message:
  
  "/home/zincum/apps/mpich2/include/mpicxx.h:2683: error: declaration of
C function void MPI::Init(int&, char**&) conflicts with
   /home/zincum/apps/mpich2/include/mpicxx.h:2682: error: previous
declaration void MPI::Init() here
   /home/zincum/apps/mpich2/include/mpicxx.h:2685: error: declaration of
C function int MPI::Init_thread(int&, char**&, int) conflicts with
   /home/zincum/apps/mpich2/include/mpicxx.h:2684: error: previous
declaration int MPI::Init_thread(int) here
  "

  Thanks in advance.

Regards,
Xin
