klish server start failing with latest 3.0.0

[Saurabh Sarpal]

On `Ubuntu 20.04.5 LTS`, built the latest version `3.0.0`

git clone https://src.libcode.org/pkun/faux.git
cd faux
./autogen.sh && ./configure && make && sudo make install

cd ..
git clone https://src.libcode.org/pkun/klish.git
cd klish
./autogen.sh && ./configure && make && sudo make install

Trying to start the server ...

/usr/local/bin/klishd -d -v -f ./klishd.conf
klishd: Parse config file: ../klishd.conf
klishd: opts: Foreground = true
klishd: opts: Verbose = true
klishd: opts: LogFacility = daemon
klishd: opts: PIDPath = /var/run/klishd.pid
klishd: opts: ConfigPath = ../klishd.conf
klishd: opts: UnixSocketPath = /tmp/klish-unix-socket
klishd: opts: DBs = libxml2
klishd: Start daemon.
Scheme errors:
DB "libxml2": kdb-libxml2.so: cannot open shared object file: No such file or directory
DB "libxml2": Can't load DB plugin
klishd: Stop daemon.

Am I doing something wrong here?

Eventually I am trying to connect the client to the server.

Try:

for faux:

./configure --prefix=/usr ...

and for klish:

./configure --prefix=/usr --with-libxml2

Thanks, that helped. Now it's hitting an assert failure ...

$ klishd -d -v -f ./klishd.conf
klishd: Parse config file: ./klishd.conf

klishd: opts: Foreground = true
klishd: opts: Verbose = true
klishd: opts: LogFacility = daemon
klishd: opts: PIDPath = /var/run/klishd.pid

klishd: opts: ConfigPath = ./klishd.conf

klishd: opts: UnixSocketPath = /tmp/klish-unix-socket
klishd: opts: DBs = libxml2
klishd: Start daemon.

klishd: Create listen UNIX socket: /tmp/klish-unix-socket
klishd: Listen socket 3

klishd: Service process for client was forked: 93068
klishd: klish/ktp/ktpd_session.c:84: ktpd_session_new: Assertion `ktpd->session' failed.
klishd: Service process 93068 was terminated by signal: 6

I ran klishd in gdb ...

(gdb) bt

Also, found that in ksession_new(), since start_entry is NULL,
kscheme_find_entry_by_path() ends up looking for the main entry which it is not able to find.
Hence, it returns NULL but the caller expects something valid and asserts.

What am I missing here?

[Serj Kalichev]

Do you have VIEW with name "main"?

It's default view for klish3.

I am not sure. Where should I look?

As mentioned below, I started the server using the default klishd.conf that comes with the package ...

klishd -d -v -f ./klishd.conf

[Serj Kalichev]

Klish to work needs XML configuration (not klishd.conf) with commands definition. See examples within klish source tree. These config must be located in ~/.klish dir. Config must contain "VIEW" called "main".
