On Mac OS, since we call WaitNextEvent, this process will show up in the dock unless we set the LSBackgroundOnly flag in the Info.plist.
On Mac OS, since we call WaitNextEvent, this process will show up in the dock unless we set the LSBackgroundOnly or LSUIElement flag in the Info.plist.
Normally non-bundled binaries don't have an info.plist file, but it's possible to embed one in the binary by adding this to the linker flags:
-sectcreate __TEXT __info_plist /path/to/slplugin_info.plist
which means adding this to the gcc flags:
-Wl,-sectcreate,__TEXT,__info_plist,/path/to/slplugin_info.plist
Now that SLPlugin is a bundled app on the Mac, this is no longer necessary (it can just use a regular Info.plist file), but I'm leaving this comment in for posterity.
