Hi Laurenz,
Actually,I did not specify --prefix option at all in either case.
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?
