I did this
Attempted to build 7.63.0 on OS400, fails with the following errors in curl_url_get_ccsid() packages/OS400/ccsidcurl.c
*part = dynconvert(ccsid, s, -1, ccsid, ASCII_CCSID);
*=SEVERE==========> a - CZM0099 Unexpected argument.
Looks like this was added in a77b640, I think the code should be;
*part = dynconvert(ccsid, s, -1, ASCII_CCSID);
I expected the following
Clean build
curl/libcurl version
[curl -V output]
operating system
OS400 V7R2M0
