| Changes in shipping of Editline library with Titan [message #1833409] |

Dear all,
for administrative reasons, Titan used to ship an embedded copy of the source code
of NetBSD Editline library ( libedit) version 0:35:0 located in mctr2/editline/libedit.
This is an autotool- and libtoolized port of the NetBSD Editline library (libedit).
This Berkeley-style licensed command line editor library provides generic line editing,
history, and tokenization functions, similar to those found in GNU Readline.
The original source code of the version 0:35:0 and other, mostly newer versions can be found at
http://thrysoee.dk/editline/ ,
the latest version at this moment (October 2020) being 0:63:0 , with the release date 2019-12-31.
The last version of Titan which includes Editline library in source was 7.1.1.
In later versions, Titan will rely on the Editline library being installed
on the Linux distribution it executes on. The Editline source code was removed from the repository.
This will impact the pre-requisites of building Titan from source and using Titan for compilation of TTCN-3 code in the following manner:
-Titan expects the libedit libraries to be installed on the Linux distribution.
E.g. for Ubuntu,
sudo apt install libedit2 libedit-dev
for SLES/SLED
sudo zypper in libedit0 libedit-devel
has to be executed.
For other distros, please identify the relevant packages and actions to be taken.
-for older distributions, a compiler option might be needed in Makefile.personal as below:
If the first line of /usr/include/editline/readline.h contains version 1.34 or older
(corresponding to a version of editline of 0:53:0, released 2015-03-25, or older), then the following line has to be added
to the Makefile.personal:
Later distros contain newer versions, for instance
head -2 /usr/include/editline/readline.h
/* $NetBSD: readline.h,v 1.41 2016/10/28 18:32:35 christos Exp $ */
in Ubuntu 1804
and
head -2 /usr/include/editline/readline.h
/* $NetBSD: readline.h,v 1.46 2019/06/07 15:19:29 christos Exp $ */
in Ubuntu 2004
so there's a good chance you will never encounter the necessity to use this compiler option.
Important: please don't confuse
/usr/include/editline/readline.h
with
/usr/include/readline/readline.h
The content of the latter is not relevant from the point of view of the present discourse.
The Editline library is linked to the 'mctr_cli' executable:
ldd mctr_cli
linux-vdso.so.1 (0x00007fff8f985000)
libcrypto.so.1.1 => /usr/local/ssl/lib/libcrypto.so.1.1 (0x00007f0cd6520000)
:
libedit.so.2 => /usr/lib/x86_64-linux-gnu/libedit.so.2 (0x00007f0cd62e9000)
:
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f0cd60ca000)
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f0cd5d41000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f0cd5b29000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f0cd5738000)
libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f0cd551b000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f0cd5317000)
libtinfo.so.5 => /lib/x86_64-linux-gnu/libtinfo.so.5 (0x00007f0cd50ed000)
/lib64/ld-linux-x86-64.so.2 (0x00007f0cd6cbf000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f0cd4d4f000)
or to the single mode executable built for debugging
See refererenceguide: The TTCN-3 Debugger/Debugging with the single mode UI
All the above boils down to this: from now on, one has to install Editline(libedit) libraries
in order to use Titan; this is a new dependency due to change of shipping method of Editline.
