Hi , trying to update tzdata/code on an embedded device. Last install I did was in 2016, so been a while.

System is an old linux system (GCC 4.1.2, GLIBC 2.5), with some updates over the years.

However I get a zic error on installing the zone files:

./zic: Can't link /usr/share/zoneinfo/Africa/Abidjan to /usr/share/zoneinfo/Africa/Accra: Invalid argument

Complete output:
