I just attempted the build of mod_java. The previous problem is resolved but some new issues have cropped up. There is a link problem now with unresolved symbols. Below is a trace of the build. Jonathan making all mod_java Compiling freeswitch_java.cpp... Compiling switch_swig_wrap.cpp... Compiling mod_java.c... Creating mod_java.so...
