@sgschantz are you still seeing this?

@sgschantz are you still seeing this?

I just built with master and saw no linker warnings. What did you change?

I didn't change anything… it does sound like out of date files. Let's close this and reopen if it comes back.

Sorry, not sure why I didn't see the warnings locally, but I do see these on ci builds. Check the log here for the latest build of 18.

There are many statements like this:
[18:07:04] : [Step 5/7] ld: warning: object file (/Users/marc_durdin/buildAgent/work/fae170dc1caceadf/keyman/core/build/mac-x86_64/release/subprojects/icu/source/common/libsicuuc.a[2](stubdata.cpp.o)) was built for newer 'macOS' version (14.0) than being linked (10.13)

@srl295 -- I just realized that the warnings switched from 12.0 to 14.0. Is there some way to control what version of macOS core is being built for?

Our minimum version is 10.13, and it looks like a similar issue (#9060) may be causing crashes on startup with Big Sur (11) and Catalina (10.15). I don't see any evidence that it is related to this issue, but it is interesting that it is only happening on OS versions less than 12.

I found this

$ strings ./core/build/mac-x86_64/release/meson-private/build.dat | fgrep MACOSX_DEPL
'--prefix=/usr/local/opt/[email protected]' '--enable-ipv6' '--datarootdir=/usr/local/opt/[email protected]/share' '--datadir=/usr/local/opt/[email protected]/share' '--without-ensurepip' '--enable-loadable-sqlite-extensions' '--with-openssl=/usr/local/opt/openssl@3' '--enable-optimizations' '--with-system-expat' '--with-system-libmpdec' '--with-readline=editline' '--with-lto' '--enable-framework=/usr/local/opt/[email protected]/Frameworks' '--with-dtrace' '--with-dbmliborder=ndbm' 'MACOSX_DEPLOYMENT_TARGET=14' 'CFLAGS=-isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX14.sdk' 'CFLAGS_NODIST=-I/usr/local/include' 'LDFLAGS=-isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX14.sdk' 'LDFLAGS_NODIST=-L/usr/local/lib -Wl,-rpath,/usr/local/lib' 'CPPFLAGS=-I/usr/local/include' 'py_cv_module__tkinter=disabled' 'PKG_CONFIG_PATH=/usr/local/opt/mpdecimal/lib/pkgconfig:/usr/local/opt/openssl@3/lib/pkgconfig:/usr/local/opt/readline/lib/pkgconfig:/usr/local/opt/sqlite/lib/pkgconfig:/usr/local/opt/xz/lib/pkgconfig' 'PKG_CONFIG_LIBDIR=/usr/lib/pkgconfig:/usr/local/Homebrew/Library/Homebrew/os/mac/pkgconfig/14' 'CC=clang'

(I'm on Sonoma 14.5)

so it shows MACOSX_DEPLOYMENT_TARGET=14

What we might need to do is to set this version in cmake and keep it in sync with xcode…

I also found #11302 where the xcode side was updated.

OK i was looking at the wrong build log, i see the messages now on https://build.palaso.org/buildConfiguration/KeymanMac_Master/488041?buildTab=log&focusLine=2309&logView=flowAware&expandAll=true
