Hi!
While working on the "reproducible builds" effort [1], we have noticed
that nexuiz-data could not be built reproducibly.
During build a checksum over configuration settings is calculated and
embedded in some files. The lines are sorted before generating the
checksum, but sort behaves differently depending on the configured
locale.
The attached patch sorts with the locale set to C, so that the same
values are generated independent of the current locale.
Regards,
Reiner
