Postgresql – undefined symbol: EVP_cast5_cbc when trying to use pgcrypto

Trying to use the pgcrypto extension for PostgreSQL but getting this undefined symbol: EVP_cast5_cbc whenever I try to start the server:

[postgres@localhost ~]$ pg_ctl start -D /usr/local/pgsql/data
waiting for server to start....2024-04-26 10:39:15.326 CEST [3036]: db=,user=,app=,client= LOG:  00000: pgaudit extension initialized

pg_ctl: could not start server

Postgres is compiled from source and version 15.6.

Here is my openssl version if necessary:

OpenSSL 3.0.7 1 Nov 2022 (Library: OpenSSL 3.0.7 1 Nov 2022)

ldd /usr/local/pgsql/lib/pgcrypto.so returns:

[postgres@localhost ~]$ ldd /usr/local/pgsql/lib/pgcrypto.so
    linux-vdso.so.1 (0x00007ffd2b7fc000)
    libz.so.1 => /lib64/libz.so.1 (0x00007fe818092000)
    libc.so.6 => /lib64/libc.so.6 (0x00007fe817e00000)
    /lib64/ld-linux-x86-64.so.2 (0x00007fe8180ea000)

    Something went wrong when you build pgcrypto: it should be linked with libcrypto.so. Since it isn’t, it is hardly surprising that it complains about a symbol it cannot resolve.

    Review your build process.

    Why are you compiling it from source instead of using one that is already packaged? Did you follow the compilation instructions?

    Putting your question title into Google returned this result: https://www.postgresql.org/message-id/334461.1705013937%40sss.pgh.pa.us

    If that looks like the same problem you’re having, you probably didn’t include --with-openssl on your ./configure line, which you can confirm in your config.log file. Your ldd command shows it is not linked.
