[Freeswitch-users] Building Java ESL bindings

[Daniel Wilson]

I got an esl.jar to build successfully on the same machine as I was using
for the failed build in my original post, on a clean master by doing -

- ./bootstrap -j
- ./configure (with no options this time)
- make
- cd libs/esl
- make
- edit java/Makefile to manually correct the includes for my java
installation. it now reads -
LOCAL_CFLAGS=-I../src/include -I/usr/lib/jvm/java-6-openjdk-amd64/include/
-I/usr/lib/jvm/java-6-openjdk-amd64/include/linux/
- make javamod

I'm going to work back from here and see if I can get it building on 1.6...

Cheers,

Dan
