I rebuilt and reinstalled 9.1,but now,as mentioned earlier,my project is not running successfully on it(I need the -ljvm flag in gcc for compilation.I am using PGXN and I added EXPORT CXXFLAG=$CXXFLAG "-ljvm" and EXPORT CFLAG=$CFLAG "-ljvm" to the makefile of my project.This was working till today morning,when I stupidly installed 9.2beta2 without specifying a new --prefix.) What should I do?
