oracle-jvm error...

I'm not sure how long ago this happened, but there are now lots of different JVM's available for Debian and Ubuntu systems: openjdk-6, openjdk-7, openjdk-8, oracle-jvm-7 and oracle-jvm-8. Possibly more...

SQL Relay 0.57 has no trouble detecting the openjdk's, but doesn't properly detect oracle-jvm's and the build fails. I ran into this error trying to build on a Raspberry PI running Raspbian, but a few people have reported the same error on Debian and Ubuntu sytems.

There are 3 workarounds:

Disable Java

If you're not using SQL Relay with java then you can add --disable-java to the configure command and SQL Relay won't even try to build against oracle-jvm.

Replace Oracle JVM with OpenJDK

This may be tricky. I'm not sure which packages have a hard dependency on oracle-jvm as opposed to just needing some version of Java. Your mileage may vary.

Patch the Configure Script

Edit the configure script in the SQL Relay source distribution and look for a line like:

   for i in `ls -d /usr/java/jdk* /usr/java/j2sdk* /usr/local/jdk* 2> /dev/null` /usr/java 
/usr/local/java `ls -d /usr/local/openjdk* /usr/pkg/java/openjdk* 2> /dev/null` `ls -d /usr/lib64/jvm/java 2> /dev/null` 
`ls -d /usr/lib64/jvm/java-1.8* 2> /dev/null` `ls -d /usr/lib64/jvm/java-1.7* 2> /dev/null` `ls -d /usr/lib64
/jvm/java-1.6* 2> /dev/null` `ls -d /usr/lib/jvm/java 2> /dev/null` `ls -d /usr/lib/jvm/java-1.8* 2> /dev/null` `ls -d 
/usr/lib/jvm/java-1.7* 2> /dev/null` `ls -d /usr/lib/jvm/java-1.6* 2> /dev/null` /System/Library/Frameworks
/JavaVM.framework/Versions/Current /usr /usr/local

and replace it with these lines:

   for i in `ls -d /usr/java/jdk* /usr/java/j2sdk* /usr/local/jdk* 2> /dev/null` \
    /usr/java \
    /usr/local/java \
    `ls -d /usr/local/openjdk* /usr/pkg/java/openjdk* 2> /dev/null` \
    `ls -d /usr/lib64/jvm/java 2> /dev/null` \
    `ls -d /usr/lib64/jvm/java-1.8* 2> /dev/null` \
    `ls -d /usr/lib64/jvm/java-1.7* 2> /dev/null` \
    `ls -d /usr/lib64/jvm/java-1.6* 2> /dev/null` \
    `ls -d /usr/lib64/jvm/jdk-7-* 2> /dev/null` \
    `ls -d /usr/lib64/jvm/jdk-8-* 2> /dev/null` \
    `ls -d /usr/lib/jvm/java 2> /dev/null` \
    `ls -d /usr/lib/jvm/java-1.8* 2> /dev/null` \
    `ls -d /usr/lib/jvm/java-1.7* 2> /dev/null` \
    `ls -d /usr/lib/jvm/java-1.6* 2> /dev/null` \
    `ls -d /usr/lib/jvm/jdk-7-* 2> /dev/null` \
    `ls -d /usr/lib/jvm/jdk-8-* 2> /dev/null` \
    /System/Library/Frameworks/JavaVM.framework/Versions/Current \
    /usr \
    /usr/local

One of those three solutions should work.

The source has been updated and it's fixed in CVS. The next release will include the fix too.
