pgRouting not available in pg_available_extensions even after installation.

[abrahamarslan]

I'm trying to install pgrouting extension on postgres using docker.
Here is the complete dockerfile

https://paste.gd/rc8cpoBN#

I don't get any errors and the image builds successfully. At entrypoint, I enable the extensions required using

CREATE EXTENSION IF NOT EXISTS postgis;
CREATE EXTENSION IF NOT EXISTS postgis_topology;
CREATE EXTENSION IF NOT EXISTS postgis_tiger_geocoder CASCADE;
CREATE EXTENSION IF NOT EXISTS address_standardizer;
CREATE EXTENSION IF NOT EXISTS pg_repack;
CREATE EXTENSION IF NOT EXISTS pgrouting;

But I do not see pgrouting enabled in the database, nor it is available in pg_available_extensions.

Is there a step I'm missing or is the Dockerfile wrong?

Kindly help.

Is there a step I'm missing or is the Dockerfile wrong?

It seems the installation settings might be misconfigured, which could result in pgRouting being installed in the wrong directory.
Specifically, the following settings in your Dockerfile seem unusual, especially considering you’re using Alpine and not Debian/Ubuntu:

&& cmake .. \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DPOSTGRESQL_INCLUDE_DIR=/usr/include/postgresql \
    -DPOSTGRESQL_LIBRARIES=/usr/lib/postgresql \
    -DBoost_INCLUDE_DIR=/usr/include/boost \
    -DPOSTGRESQL_SHARE_DIR=/usr/local/share/postgresql \

I suggest using the default settings provided in the https://github.com/pgRouting/pgrouting?tab=readme-ov-file#compilation
to ensure proper installation.

Here’s a tiny working example that includes a workaround using -DCMAKE_CXX_FLAGS="-include cstdint " .

FROM postgis/postgis:15-3.5-alpine

RUN apk add --no-cache \
    boost-dev \
    cmake \
    g++ \
    make \
    perl  

ENV PGROUTING_VERSION 3.7.1
RUN wget -O pgrouting.tar.gz https://github.com/pgRouting/pgrouting/archive/v${PGROUTING_VERSION}.tar.gz

RUN echo "Extracting pgrouting" \
    && tar -xvzf pgrouting.tar.gz \
    && cd pgrouting-* \
    && mkdir build \
    && cd build \
    && cmake -DCMAKE_CXX_FLAGS="-include cstdint" .. \
    && make -j4 \
    && make install \
    && cd ../.. \
    && rm -rf pgrouting*
    

and my test results:

postgres=# \dx
                                        List of installed extensions
