.bashrc question

[jmadero]

Hi All,

I just helped someone setup their CUDA drivers and in the directions on almost all the forums it said to add this:

PATH=$PATH:/usr/local/cuda/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib
export PATH
export LD_LIBRARY_PATH

to the .bashrc file. Doing that was failing as we were seeing errors when trying to run the example files provided by Nvidia. So as a home remedy I instead made a text file in /etc/ld.so.conf.d that included the path /usr/local/cuda/lib and the examples work fine....so questions:

what were all those paths for? what is bashrc for? and why is it not working from bashrc?

Thanks all!

if you have a ".bash_profile" in yr home directory,
bash will use that & never find the ".bashrc"

fix: add the line ". .bashrc" to yr ".bash_profile"
or add to it rather than to ".bashrc"

.bashrc is only loaded when you start up a new shell as well, every time you make a change to it you have to source it in any currently running shells
