warning: 'syscall' is deprecated: first deprecated in macOS 10.12 - syscall(2) is unsupported; please switch to a supported interface

[rwebaz (Robert Weber)]

Hello:

I am attaching the link to a private GIST that houses the make timeline affected.

I've also added pertinent info RE: The Development Machine ie.) Xcode tools ver, etc.

Here is the link to the private GIST ...

​https://gist.github.com/rwebaz/b71f520970c456745b4a93842a02bbe4

The links point to a (.md) file that is titled the same.

[Macports-2nd-Instance-Make-50-Count-Warnings-Syscall-Deprecated-Need-Supported-Interface.md]

Pls advise if the issue is indeed part of the Macports binary archive development (2.4.1), or if Clang is hunting for an accurately supported interface locally.

As I have installed the current version of Mac OSX Sierra (10.12.3), as well as the current version of the Xcode Developer tools (8.3), my thinking is maybe the issue is with the way the current (2.4.1) Macports binary archive was written.

Thank you!

Robert

It is true that the darwintracelib part of MacPorts does use syscall, and according to the warnings shown in your transcript this does appear to be deprecated as of Sierra, so I guess we should look for an alternative (while still maintaining compatibility with older systems).

The linked gist is completely unreadable. Terminal output is not Markdown, so please do not post it with a .md extension. As external resources tend to disappear over time, I would also appreciate to attach additional information to the ticket.

I do not understand your problem. The compiler warnings are normal and expected. syscall(2) is deprecated and the corresponding code in darwintracelib1.0 will need to be rewritten in the future.
