No I didn't. This is one area where my understanding of linux is a 
little sketchy. I shall check it.

Edit: after running "sudo ldconfig" it works to run ecppc inside 
Code::Blocks also on the PI!

I had put the following in /etc/environment

export PATH=$PATH:/USB_pihdd/cpde3/usr/bin
export LD_LIBRARY_PATH=$PATH:/usr/local/lib
export LD_RUN_PATH=$LD_LIBRARY_PATH

The above was an attempt to make it work. And it did work from the 
terminal, only not within Code::Blocks. I guess that is a question about 
how Code::Blocks works on the PI, and not really Tntnet.

I find it confusing that there are so many places these definitions can 
go. Some people suggest ~/.bashrc, some /etc/environment and now you 
suggest /etc/ld.conf which is new to me (and it doesn't exist on my 
Raspberry PI as of now).

Maybe it is /etc/ld.so.conf ? It contains the confusing line:
include /etc/ld.so.conf/*.conf

I must admit I have some problems understanding how/where these things 
are to be properly set up and work. But from the above it is shown that 
running only ldconfig was all that was really needed in this case.

Thanks again & best regards
