Hi all:
Thank you in advance.
I have use the tool “gr_modtool” to create a cpp document.But
an error exists:
ImportError: /usr/local/lib/libgnuradio-mimo.so: undefined
symbol: _ZTIN2gr4mimo21csi_int_cfo_vcvc_implE
I have search the maillist,and find “sudo ldconfig” to solve it.But when
I use the “sudo ldconfig”,the error also exists.
Can someone help me?
Best regards,
zs

Is there a way to use Python’s math.log() in the value field of a
variable in gnuradio-companion? It seems like I can only use the Python
built in functions.

AFAIK, there is an Import block in GRC.
