Re: [Discuss-gnuradio] Import Error running companion after upgrade to Fedora 27

[Mike Gilmer]

Yes, thanks - I figured out I needed to have been doing that. ;-)

What a drudgery - I had to make changes to many files to get as far as I've gotten (now up to 87% finished) and now I'm getting the errors:

/usr/bin/ld: warning: libboost_date_time.so.1.58.0, needed by /usr/local/lib64/libuhd.so, not found (try using -rpath or -rpath-link)

/usr/bin/ld: warning: libboost_filesystem.so.1.58.0, needed by /usr/local/lib64/libuhd.so, not found (try using -rpath or -rpath-link)

/usr/bin/ld: warning: libboost_program_options.so.1.58.0, needed by /usr/local/lib64/libuhd.so, not found (try using -rpath or -rpath-link)

.

.

.

Any ideas?

Thanks.

Mike

Import errors can happen for a variety of reasons, even if the packages are still in the right place. A common reason is that libraries provided by rpms, and that gnuradio depends on, have changed. Since Boost has changed to version 1.64 in Fedora 27, you'll have to rebuild gnuradio.

I recently upgraded my Fedora 23 laptop (on which gnuradio companion worked fine) to Fedora 27

Now when I try to run gnuradio-companion I get an error window.

                   ImportError
Cannot import gnuradio.

Is the python path environment variable set correctly?
     All OS: PYTHONPATH

Is the library path environment variable set correctly?
     Linux: LD_LIBRARY_PATH
     Windows: PATH
     MacOSX: DYLD_LIBRARY_PATH

(libboost_date_time.so.1.58.0: cannot open shared object file: No such file or directory)

I've checked the two env variables and they are set properly AFAIK.

$ echo $PYTHONPATH
/usr/local/lib64/python2.7/site-packages


$ echo $LD_LIBRARY_PATH
/usr/lib64

Any advice would be appreciated.
