I am trying to configure my JMagick installation, however when I run ./configure I receive an error saying that it is 'Unable to locate Java directories:'

./configure

configure: error: 'Unable to locate Java directories'

I know that the configure is looking for java, javac, jar, and gcc. When I type whereis on each of these items I see that they are all on my $PATH in /usr/bin (I even added each to the path individually):

PATH=/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/bin/java:/usr/bin/javac:/usr/bin/jar:/usr/bin/gcc



whereis java javac jar gcc



java: /usr/bin/java  /etc/java  /usr/lib/java  /usr/share/java /usr/share/man/man1/java.1.gz

javac: /usr/bin/javac  /usr/share/man/man1/javac.1.gz

jar: /usr/bin/jar  /usr/share/man/man1/jar.1.gz

gcc: /usr/bin/gcc  /usr/lib/gcc  /usr/libexec/gcc  /usr/share/man/man1/gcc.1.gz

From what I was able to find, I believe I need to set a JAVA_HOME environmental variable. So I did:

JAVA_HOME=/usr/bin/java

Nevertheless, I still get the Unable to locate Java directories error.

The current versions of the various technologies running on the VM are:

java version "1.7.0_09-icedtea"

OpenJDK Runtime Environment (rhel-2.3.4.1.el6_3-x86_64)

OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)



javac 1.7.0_09



gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-3)

The JAVA_HOME variable should be set to the folder of JDK installation.
In you case, instead, it is set to the binary executable.

So replace of

 

JAVA_HOME=/usr/bin/java

with actual folder.
To find the folder, try

  ls -lh /usr/bin/java # this should be a sym link to an actual file

EDIT: Changed command from ln to ls
