Hello,
I am trying to call a g95 fortran routine from a C(++) main file.
Here are the 2 files:
globalMain.c:
#include <iostream>
using namespace std;
extern"C" {
void fortfunc_(int *ii, float *ff);
}
int main( int argc , char* argv[] )
{
int ii=5;
float ff=5.5;
fortfunc_(&ii, &ff);
return 0;
}
functF.f:
subroutine fortfunc(ii,ff)
integer ii
real*4 ff
write(6,100) ii, ff
100 format('ii=',i2,' ff=',f6.3)
return
end
I installed (without any problem) the lam mpi with the g95 fortran compiler.
My makefile is:
CC=mpiCC
FC=mpif77
each:
$(CC) -c globalMain.c
$(FC) -c -fno-second-underscore -fno-underscoring functF.f
all:
$(CC) globalMain.o functF.o -o go
As a result, "make each" runs find: no error message.
But "make all" fails:
mpiCC globalMain.o functF.o -o go
functF.o: In function `fortfunc':
functF.f:(.text+0x19): undefined reference to `_g95_get_ioparm'

Attached is my config.log, and below the laminfo output.
Any comment will be greatly appreciated. Thanks.
