Thanks Harald for your quick response. I just updated the libosmocore version and run make again, this time with a different error.

usr/bin/ld: main.o: undefined reference to symbol '_talloc_zero_array@@TALLOC_2.0.2'
//usr/lib/i386-linux-gnu/libtalloc.so.2: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
Makefile:388: recipe for target 'bcch_scan' failed

I've tried adding the math library to configure.ac <http://configure.ac> but it still fails.

It seems the libtalloc installed in your host pc is too old.

I have libtalloc.2.1.10 and the symbol is there:
$ strings /usr/lib/libtalloc.so.2.1.10 | grep _talloc_zero_array
_talloc_zero_array

Please make sure the libtalloc in your system has that symbol in, otherwise update it to a newer version. You can check through git log to see when was that symbol added, and infer from that which minimum libtalloc verison you need. I guess we should be checking that during configure time in osmocom-bb.
