Hi all,
I tried to compile the C++ program listed in the openbabel web site
(http://openbabel.org/docs/dev/UseTheLibrary/CppExamples.html#using-makefiles)
according to the instructions of "How to compile against the open babel
library". But some errors occurred. The hints given by the compiler are "
OBConversion was not declared in this scope ", OBMol was not declared in this
scope. The Makefile is :
CC= g++
CFLAGS= -c -I
/home/duanbg/program/openbabel-2.3.2/include/openbabel-2.0LDFLAGS= -lopenbabel
-L /home/duanbg/program/openbabel-2.3.2/lib
all: example
example: example.o
$(CC)$(LDFLAGS) example.o -o example
example.o: example.cpp
$(CC)$(CFLAGS)$(LDFLAGS) example.cpp
clean:
rm -rf example.o example
**********************************
//example.cpp
#include <iostream>
#include <openbabel/obconversion.h>
#include <openbabel/mol.h>
intmain(intargc,char**argv)
{
OBConversionobconversion;
obconversion.SetInFormat("sdf");
OBMolmol;
boolnotatend=obconversion.ReadFile(&mol,"../xsaa.sdf");
while(notatend)
{
std::cout<<"Molecular Weight: "<<mol.GetMolWt()<<std::endl;
mol.Clear();
notatend=obconversion.Read(&mol);
}
return(0);
}
*****************************************
Would you like to give me some help? Thanks in advance.
Best Wishes
Baogen Duan
