Installing and using the ParMetis library - c++

Question

I am installing ParMetis 4.0.3 but into a non-default directory, with:
make config prefix=/My-ParMETIS-Directory/
And afterward:
make install
After that, I get a set of directories in that folder. And to write a program that uses it, I'm supposed to add the 'include "parmetis.h"' in the headline, and also add the 'libraries/binaries'. How exactly do I do the latter?
I'm just trying to get my code to compile now, and doing so I run:
g++ test.cpp
This is test.cpp:
#include<iostream>
#include "include/parmetis.h"
using std::cout;
using std::endl;
int main()
{
cout << "Test!" << endl;
return 0;
}
I keep getting "was not declared in this scope" for everything/every-line in parmetis.h.
How can I get test.cpp use the other folders/files that were installed?

Answer 1

You need to provide the location of your ParMetis library to
the compiler, since you have choosen to install the library
not in the default library directories.
mpic++ test.cpp -I /My-ParMETIS-Directory/ -I /My-METIS-Directory/
Edit#2:
What I did to get your code compiling:
Download the ParMetis library from webpage to /tmp
cd /tmp/
wget http://glaros.dtc.umn.edu/gkhome/fetch/sw/parmetis/parmetis-4.0.3.tar.gz
Unpack archive
tar -xf parmetis-4.0.3.tar.gz
Install ParMETIS into directory /tmp/parmetis
mkdir parmetis
cd parmetis-4.0.3/
make config prefix=/tmp/parmetis
make install
Install METIS into directory /tmp/metis
cd /tmp/
mkdir metis
cd parmetis-4.0.3/metis
make config prefix=/tmp/metis
make install
Compile test.cpp which is located in /tmp/
cd /tmp/
mpic++ test.cpp -I /tmp/parmetis -I /tmp/metis

when you coding wtih C++ ,if you meet question like that :
ccJjiCo.o: In function `main':
bsplele.cpp:(.text+0x45e): undefined reference to `METIS_PartMeshNodal'
collect2: ld returned 1 exit status
you can check the compiler sentence and you should paste the -lmetis at the end of the compilation command.It is useful for me.
my right compilation command is that:g++ -L/home/hadoop/metis/lib -I/home/hadoop/metis/include/ LL_metis.cpp -lmetis
