I uploaded MariaDB Connector C 2.3.2 to Debian yesterday. Today the build logs reveal that it does not build for mips and s390x: https://buildd.debian.org/status/package.php?p=mariadb-connector-c
They are both official Debian architectures and the package must build on them. This is a regression, since 2.3.1 built fine on both:
The error message looks identical, so the same fix should apply to both.
Please debug and submit the fix as a patch on https://github.com/ottok/mariadb-connector-c/tree/master/debian/patches. If needed, please ask Vicențiu Ciorbaru help on how to debug, test and submit Debian packaging formatted patch.
