[srslte-users] Ettus E312 build

[Pedro Alvarez]

Hi Ed,

In old systems, there seems to be an issue in redefinition of
structure necessary for IPv6 support.
Can you compile using the following command first:
"""
cmake -DUSE_GLIBC_IPV6=False ../
make
"""

Cheers,
Pedro

The embedded image that comes from Ettus is pretty minimal; I had to make/install libconfig, lksctp-tools, and mbedtls from source. Everything went well, and cmake successfully generates the makefile in the build/ directory, but the make fails here:
