[bug?] No readline support in Lua 5.4 REPL

[Martin <dyngeccetor8@...>]

Hello list,

I'm trying Lua 5.4.0 and can't get libreadline work in REPL mode.
Package "libreadline-dev" is installed. In Lua 5.3.5 REPL cursor
arrows works fine.

1. I'm installing Lua 5.4 as following:

--
#!/bin/bash

url="http://www.lua.org/ftp/lua-5.4.0.tar.gz";

cd /tmp
curl -R -O $url
tar zxf $(basename $url)
cd $(basename $url .tar.gz)
sudo make linux-readline install
--

1.1 Output is:

--
make[1]: Entering directory '/tmp/lua-5.4.0/src'
make all SYSCFLAGS="-DLUA_USE_LINUX -DLUA_USE_READLINE" SYSLIBS="-Wl,-E 
-ldl -lreadline"
make[2]: Entering directory '/tmp/lua-5.4.0/src'
make[2]: Nothing to be done for 'all'.
make[2]: Leaving directory '/tmp/lua-5.4.0/src'
make[1]: Leaving directory '/tmp/lua-5.4.0/src'
cd src && mkdir -p /usr/local/bin /usr/local/include /usr/local/lib 
/usr/local/man/man1 /usr/local/share/lua/5.4 /usr/local/lib/lua/5.4
cd src && install -p -m 0755 lua luac /usr/local/bin
cd src && install -p -m 0644 lua.h luaconf.h lualib.h lauxlib.h lua.hpp 
/usr/local/include
cd src && install -p -m 0644 liblua.a /usr/local/lib
cd doc && install -p -m 0644 lua.1 luac.1 /usr/local/man/man1
--

1.2 Test: type "lua", newline, any character, newline, press UP arrow:

> a
nil
> ^[[A
--

2. When I'm installing Lua 5.3 as following:

--
url="http://www.lua.org/ftp/lua-5.3.5.tar.gz";

cd /tmp
curl -R -O $url
tar zxf $(basename $url)
cd $(basename $url .tar.gz)
sudo make linux install
--

2.1 Output is:

--
cd src && make linux
make[1]: Entering directory '/tmp/lua-5.3.5/src'
make all SYSCFLAGS="-DLUA_USE_LINUX" SYSLIBS="-Wl,-E -ldl -lreadline"
make[2]: Entering directory '/tmp/lua-5.3.5/src'
make[2]: Nothing to be done for 'all'.
make[2]: Leaving directory '/tmp/lua-5.3.5/src'
make[1]: Leaving directory '/tmp/lua-5.3.5/src'
cd src && mkdir -p /usr/local/bin /usr/local/include /usr/local/lib 
/usr/local/man/man1 /usr/local/share/lua/5.3 /usr/local/lib/lua/5.3
cd src && install -p -m 0755 lua luac /usr/local/bin
cd src && install -p -m 0644 lua.h luaconf.h lualib.h lauxlib.h lua.hpp 
/usr/local/include
cd src && install -p -m 0644 liblua.a /usr/local/lib
cd doc && install -p -m 0644 lua.1 luac.1 /usr/local/man/man1
--

2.2 Readline works as expected:

> a
nil
> a
--

3. `apt show libreadline-dev`
