The solution proposed by Márton Németh works for me when I make sure that
the appropriate shared libraries are used, e.g. by using:
$ perl -pi.bak -e 's/(#define.*WTAP_MAX_PACKET_SIZE).*/\1 262143/' wiretap/wtap.h
$ env LD_LIBRARY_PATH=/usr/local/wireshark-xxl/lib/ LD_RUN_PATH=/usr/local/wireshark-xxl/lib/ ./configure --prefix=/usr/local/wireshark-xxl
$ env LD_LIBRARY_PATH=/usr/local/wireshark-xxl/lib/ LD_RUN_PATH=/usr/local/wireshark-xxl/lib/ make
$ env LD_LIBRARY_PATH=/usr/local/wireshark-xxl/lib/ LD_RUN_PATH=/usr/local/wireshark-xxl/lib/ make install
$ tshark -r /tmp/test2.pcap
tshark: "/tmp/test2.pcap" appears to be damaged or corrupt.
(pcap: File has 65611-byte packet, bigger than maximum of 65535)
$ /usr/local/wireshark-xxl/bin/tshark -r /tmp/test2.pcap
tshark: "/tmp/test2.pcap" appears to have been cut short in the middle of a packet.
