PKG_CONFIG_PATH problem

[<sasank kuntimaddi wipro com>]

Hi

 

I have a strange problem here. I had configured and exported PKG_CONFIG_PATH on my pc and I am using `pkg-config --cflags --libs gtk+-2.0` for compiling my code.
Everything worked fine untill I had to add libgnomecanvas path to the existing PKG_CONFIG_PATH. So I decided to check the original PKG_CONFIG_PATH [a sanity check] before I modify it. But I cannot find the existing PKG_CONFIG_PATH in env & echo $PKG_CONFIG_PATH returns NULL. But strangely the code compiles
So where is the PKG_CONFIG_PATH I had set?

 

Thanks & Regards
