problems compiling 3.17.2 on Ubuntu 16.0.4 with java
I am trying to build syslog-ng with java and json support on Ubuntu 16.0.4. I can’t use prepackaged version because ubuntu have decided that one must not have both rsyslog (which is our corporate standard) and syslog-ng (which I need for its pattern matching in an application) on the same machine. Installing one package removes the other. As well as the standard build tools I have installed these packages via apt: jsoncpp, jre and gradle. Simply running ./configure ran through but did not find java (i.e. java and java-module were both set to no). I added —enable java and configure terminated complaining that it could not find java. I dug into the configure script and found that it was executing “which javac” and “javah” both of which failed. I changed JAVAC to “java” and the configure script then completed with both java and java module enabled. Running make then failed builder@secgendev02:~/src/syslog-ng-3.17.2$ make mkdir -p modules/java/syslog-ng-core/classes GEN modules/java/syslog-ng-core/classes/org/syslog_ng/LogMessage.class Unrecognized option: -d Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. Makefile:20740: recipe for target 'modules/java/syslog-ng-core/classes/org/syslog_ng/LogMessage.class’ failed I am guessing that the version of java the jre package installed is not compatible with the configure script. builder@secgendev02:~/src/syslog-ng-3.17.2$ java -version openjdk version "1.8.0_181" OpenJDK Runtime Environment (build 1.8.0_181-8u181-b13-0ubuntu0.16.04.1-b13) OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode) I know that configure checks the java version so I am somewhat surprised… Any Ideas on what to try next?

Hello, In order to compile syslog-ng with java, you must have javac (and javah). Simply replacing javah/c with java is not okay, they are different and not interchangeable. You must have JRE to run java based destination which you've installed, but to compile you must have JDK, which shall contain javah/c. -- Kokan On Mon, 3 Sep 2018, 11:06 pm Russell Fulton, <r.fulton@auckland.ac.nz> wrote:

I am guessing that the version of java the jre package installed is not compatible with the configure script.
