[Lazarus] Issue compiling under MacOS

[Michael Thompson]

G'day,

Apologies for this.  I've just bought a MacMini specifically for Laz
development, and I'm stuck with an issue that seems be plaguing several
other projects.  The apologies are because I'm new to Mac, I might not be
reporting this correctly - and the info to resolve may be on the web, our
forum or this mailing list, but I'm not finding it.

if I run the build script direct, I get the following output:
mike at Mikes-Mac-mini uBee512Launcher % ./ppaslink.sh
ld: warning: -multiply_defined is obsolete
-macosx_version_min has been renamed to -macos_version_min
ld: warning: ignoring duplicate libraries: '-lc'
ld: library 'c' not found
An error occurred while linking

This is exactly the build error I'm getting from within Lazarus, when I try
to build my Project.

I've tried hand editing the .sh file and removing entries from the .res
file (so I could give you more insight into what might need changing), but
I don't know what I'm doing, and I never got a workable project.  Adding
-ld_classic as per
https://stackoverflow.com/questions/77153800/xcode-15-c-compilation-errors
got me nowhere.

Searching for these linker errors gets me a whole slew of recent posts from
other projects saying that build scripts need to be updated for a new
linker in XCode 15 (which is why I started poking around with the
ppaslink.sh script).

I'm not sure how to install the 'c' library (on linux I'd be apt'ing round
about now)

I'm using XCode Command Line Tools 15.1 / macOS 14.2.
I'm unable to revert to any XCode Command Lines from the 14.x range "your
OS is too new".
My Mac Mini is Intel based.

I've tried this with and without XCode installed (seems to be a separate
product)

I've also bumped an identical post on the forum:
https://forum.lazarus.freepascal.org/index.php/topic,65153.msg501604/topicseen.html#new

Help :-(

Mike
