I can't install gnu-crypto library

[benaddi]

Hi,
I want to install gnu-crypto library in my pc.
I downloaded the package from the web site http://www.gnu.org/software/gnu-crypto/.
Then i extracted it.
After i wanted to install this package using the following commands ./configure -> make -> make install.
When i launched ./configure, i got the following result:
assouma@assouma-laptop:~/Téléchargement/gnu-crypto-2.1.0$ ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking how to create a ustar tar archive... gnutar
checking whether to enable maintainer-specific portions of Makefiles... no
You have no CLASSPATH, I hope it is good
checking for jikes... no
checking for javac... javac
checking if javac works... yes
checking for kaffe... no
checking for java... java
checking for uudecode... yes
checking if uudecode can decode base 64 file... yes
checking if java works... configure: error: The Java VM java failed (see config.log, check the CLASSPATH?)

I trayed to inderstand the cause with the config.log file, so i had this cause:
configure:2295: checking if java works
configure:2328: java Test
Exception in thread "main" java.lang.NoClassDefFoundError: Test

Could not find the main class: Test. Program will exit.

configure: failed program was:

public class Test {
public static void main (String args[]) {
System.exit (0);
} }
configure:2337: error: The Java VM java failed (see config.log, check the CLASSPATH?)

So any one please suggest how i can install this package.

Thanks & Regards,
