Re: [Discuss-gnuradio] log4cpp library not found

[lists]

Only /home was saved , but there was no code there. I kind of wished I had 
mirrored /usr/local because it was a lot of work to build some of the code 
again, but that wouldn't be a clean installation.  

How is this for an idea? Log4cpp isn't unique to gnuradio. I will dig around 
for some program that also uses log4cpp and see if the installation works. It 
would have to be code using cmake. 

I did a google on log4cpp dependency and found this:
https://github.com/avxsynth/avxsynth/wiki

‎I don't have to install it, just try to build it and see if it finds my 
log4cpp.

You said you didn't mirror /usr/local, does that imply you copied over
other things?

Best regards,
