C++ MPI ラッパーを MPI Fortran ライブラリにコンパイルしようとしていますが、リンクに失敗します。ラッパーは次を使用してコンパイルされます
mpic++ -c my_wrapper.cc -o my_wrapper.o
my_wrapper.cc の読み取り:
#include "mpi.h"
extern"C" {
void fortran_func_(int * comm,bool *do_init);
}
void c_func(MPI_Comm my_comm )
{
MPI_Fint fcomm;
fcomm = MPI_Comm_c2f(my_comm);
bool do_init = false;
fortran_func_(&fcomm, &do_init);
}
ライブラリは次を使用してコンパイルされます
MPI_LINK_FLAGS = $(shell mpic++ --showme:link)
mpif90 -shared my_wrapper.o $(FORTRAN-LIBS) $(MPI_LINK_FLAGS) -o my_libc++.a
リンクエラーは次のとおりです。

そのようなことを行う方法の例 (Fortran/C++ と MPI の混合) を見つけることができなかったので、ある時点で他の誰かに役立つことを期待してここに質問します。
PS
でコンパイルしようとするとmpic++
:
MPIF_LINK_FLAGS = $(shell mpif90 --showme:link)
mpic++ -shared my_wrapper.o $(FORTRAN-LIBS) $(MPIF_LINK_FLAGS) -o $@
$(FORTRAN-LIBS) から多くのシンボルを見逃していmpif90
ます。したがって、不足しているライブラリを Fortran リンカに追加したほうがよいと思います。
Open MPI: 1.6
大事なら使います。
EDIT1 : それらをmpif90に追加して、すべてをリンクするとコンパイルされます:
-L/opt/local/lib/gcc47/ -lstdc++
実際、いくつかの標準 C++ が欠落していました
