Are you using those cmake flags to build MPM, or build UHD? If you're not modifying MPM (i.e., you just want to upgrade to the latest official version) we recommend simply updating the filesystem. There sometimes are more things than MPM that need changing (kernel version, other libraries, ...) and the filesystem will have everything matching. See the manual for details: https://files.ettus.com/manual/page_usrp_e3xx.html#e3xx_getting_started_fs_update
If you do want to compile MPM, I recommend the manual: https://files.ettus.com/manual/page_usrp_e3xx.html#e3xx_software_dev It has the correct compiler flags. --M On Thu, Sep 16, 2021 at 8:46 PM <[email protected]> wrote: > I think maybe I made progress by running the build multiple times, but now > when I try to start up the usrp-hwd service, I get: > > Traceback (most recent call last): > > File "/usr/bin/usrp_hwd.py", line 15, in <module> > > import usrp_mpm as mpm > > File "/usr/lib/python3.7/site-packages/usrp_mpm/__init__.py", line 19, in > <module> > > from . import libpyusrp_periphs as lib > > ImportError: > /usr/lib/python3.7/site-packages/usrp_mpm/libpyusrp_periphs.so: undefined > symbol: _ZTIN3uhd16filter_info_baseE > > > I guess I’ll just switch back to 4.0 for now. > > > _______________________________________________ > USRP-users mailing list -- [email protected] > To unsubscribe send an email to [email protected] >
