Hi, I worked to cd build/
but the build folder has CMakeCache.txt and CMakeFiles folder.
Execute make is not working, since make can not find make file.
How to change?

omarish commented Feb 27, 2015

@zizhaozhang I got something similar, sudo apt-get install m4 did the trick.

while executing the command createlang plpythonu db

Getting this error.

createlang: could not connect to database db: FATAL: role "root" does not exist

How to solve it!

Hope someone mentions. we can download the .rpm packages and to install in Ubuntu just convert the package to .deb using "Alien command" it will work.

Let me know if you need help
