Yup, this did exactly what I needed. -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Richard Way Sent: Friday, April 30, 2021 9:06 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: How to specify logical SYSLIB when linking with xclang++ under uss
Thanks! I believe this is exactly what I need to do, and in fact I had an edit session going on a config customization for syslib_x when I spotted your reply! Much appreciated. -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of David Crayford Sent: Thursday, April 29, 2021 5:46 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: How to specify logical SYSLIB when linking with xclang++ under uss I would use a configuration file. Copy /usr/lpp/cbclib/xlclang/etc/xlclang.cfg into one of your directories and either set the XL_CONFIG environment variable or include it with the -F compiler option.
