This ./config is strange:
checking for flxmlrpc >= 1.0.1... no
checking for libmbedtls >= 2.16.0... no
and flidigi use internal lib
? libmbedtls .................. internal lib
? flxmlrpc .................... internal lib
If I check with apt
libflxmlrpc-dev/oldstable,now 0.1.4-5+b6 armhf [installed]
? fldigi suite XmlRpc library - Development files
libflxmlrpc1/oldstable,now 0.1.4-5+b6 armhf [installed,automatic]
? fldigi suite XmlRpc library
libmbedtls-dev/oldstable,now 2.16.9-0.1 armhf [installed]
