make install-full fails due to being unable to find libhtp.so.2
Encountered this bug when compiling suricata 4.1.0 on Ubuntu 16.04.5 and 18.04.1
When running make install-full, suricata-update fails to run because it attempts to execute "suricata --build-info" as a part of the rule update and download process. Suricata states that it doesn't know where libhtp.so.2 is. libhtp.so.2 gets compiled as installed as a part of the build process, but the system doesn't know that until you run ldconfig. Only problem is, ldconfig is not ran before suricata-update is ran, so make install-full exits with a nonzero status, and suricata-update won't run until the system is rebooted, or ldconfig is ran. It was recommend that perhaps LD_PRELOAD could be set (e.g. LD_PRELOAD=/path/to/libhtp.so.2) so that the system tries to look for libhtp in the location its supposed to be when make install-full is executed, but I haven't tested this as a solution yet. My current work-around involves running make install, followed by ldconfig, followed by make install-full so that suricata-update runs successfully
Operating Systems affected: Ubuntu 16.04.1 and 18.04.1
Problem: make install-full exists with nonzero status; suricata-update fails to run due to suricata --build-info command failing to run. Root cause is system not knowing where libhtp is.
Expected Result: suricata-update doesn't fail to run with running make install-full
Work-around: run make install, ldconfig, then make install-full for system to register where the libhtp library is, so that suricata-update runs successfully.
