I did this

Attempted to build libcurl 7.64.1 on os400 V7R2M0:
CPD5D02: Definition not found for symbol 'Curl_vsetopt'.
CPD5D19: 1 warnings were issued from binder language compilation.
CPF5D05: Service program LIBCURL not created.

This looks like it may have been as a result of converting Curl_vsetopt() to a static function vsetopt() in lib/setopt.c, however there is still a call to Curl_vsetopt() in packages/OS400/ccsidcurl.c.

I expected the following

A clean build

curl/libcurl version

7.64.1

operating system

IBM i V7R2M0
