Maybe @linuxmaniac can comment on it -- not sure if the required library is available or simply not added to packaging.

from the README at src/modules/jwt

2.2. External Libraries or Applications

   The following libraries or applications must be installed before
   running Kamailio with this module loaded:
     * libjwt - minimum version 1.12.0.

https://packages.debian.org/search?keywords=libjwt

1.10.2-1 is the last version packaged

@hance2010 How did you fix this? I am having the same issue:

$ kamailio -v
version: kamailio 5.5.3 (x86_64/linux) 315b22
....

$ apt list libjwt*
libjwt-dev/testing,now 1.12.0-1~bullseye-bullseye amd64 [installed]
libjwt-gnutls-dev/stable 1.10.2-1 amd64
libjwt-gnutls0/stable 1.10.2-1 amd64
libjwt0-dbgsym/testing 1.12.0-1~bullseye-bullseye amd64
libjwt0/testing,now 1.12.0-1~bullseye-bullseye amd64 [installed,automatic]

OS: Debian 11

jwt is not on debian packages unfortunately:

so, it won't magically appear when you just install libjwt as they state above. you can compile kamailio on deb11 and then move the jwt.so to your production until they notice this and add it to deb packaging finally.

note also the requirement of libjwt >= 1.12.0, which is probably why they don't have it as at least on buster they don't have an updated libjwt. centos has it however on epel.

[bmlkc]

here is a builder for buster:

# build JWT
FROM debian:buster-slim AS jwt

RUN sed -i 's/httpredir/deb/g' /etc/apt/sources.list
# build tools
RUN rm -rf /var/lib/apt/lists/* && \
               apt-get update && \
               apt-get install --assume-yes gnupg wget git gcc g++ make flex bison autoconf pkg-config libssl-dev unzip libtool check 
 
# libjansson & libjwt
RUN apt-get install --assume-yes libjansson-dev && \
    cd /usr/local/src && \
    wget https://github.com/benmcollins/libjwt/archive/refs/tags/v1.12.1.zip && \
    unzip v1.12.1.zip && \
    cd libjwt-1.12.1 && \
    autoreconf -i && \
    ./configure && \
    make all && \
    make check && \
    make install

# kam compile
RUN mkdir -p /usr/local/src/kamailio-5.5 && \
    cd /usr/local/src/kamailio-5.5 && \
    git clone --depth 1 --no-single-branch https://github.com/kamailio/kamailio kamailio && \
    cd kamailio && \
    git checkout -b 5.5 origin/5.5 && \
    make PREFIX="/usr/local/kamailio-5.5" include_modules="jwt" cfg && \
    make Q=0 all && \
    make install 
 
# copy files from: 
# /usr/local/lib/libjwt.so*
# /usr/local/src/kamailio-5.5/kamailio/src/modules/jwt/jwt.so => /usr/lib/x86_64-linux-gnu/kamailio/modules/

notice no need to copy libjansson, assuming kamailio installed it for other json modules.

e.g. if you do a multi-stage:

COPY --from=jwt /usr/local/lib/libjwt.so* /usr/lib/x86_64-linux-gnu/
COPY --from=jwt /usr/local/src/kamailio-5.5/kamailio/src/modules/jwt/jwt.so /usr/lib/x86_64-linux-gnu/kamailio/modules/

Sweet. Thanks. I ended up compiling Kamailio with the jwt module as you mentioned.

Thanks for the script @bmlkc !
