This deals with two casting issues for compiling under go 1.11:
- explicitly cast to *C.xentoollog_logger for Ctx.logger pointer
- add cast to unsafe.Pointer for the C string cpath

Per the suggestion on IRC, I did a test compile with golang 1.10.8 as the version available with Ubuntu 18.04 was 1.10.1. Since this matters, the environment was setup with Xen 4.12 tools. If there are additional variations you would like to see, please let me know as I am using a docker container setup for reproducible build environments and should be able to spin up different variations fairly easily. > This should be considered for backport as well (cc'ing Jan). > Ack and thank you.

CentOS7 used to ship golang 1.9 in CentOS 7.5 and earlier (in extras repo), but currently in CentOS 7.6+ has golang 1.10 (in SCL) and 1.11 (in epel) available.

I guess so. Sorry, I didn't realize Ian was doing the tools backports. -George _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel

My change to the MAINTAINERS file hasn’t yet been merged; I think it would be good to wait until the tools maintainer (who technically is currently the maintainer) can Ack the patch. I’ll ping Ian privately to make sure he doesn’t miss it. -George _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel

OK, he’s acked it privately, so I’ll check that in and then catch these. -George _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
