I'm still seeing this in last Friday's bootstraps:
macOS/Darwin versions Xcode version
12.7.2 (21G1974)/21.6.0 14.2
13.6.3 (22G436)/22.6.0 14.3
14.2.1 (23C71)/23.2.0 15.1
The full configure line for macOS 14 is
/usr/local/bin/bash /vol/gcc/src/hg/master/darwin/configure --prefix=/vol/gcc
--target=x86_64-apple-darwin23.2.0 --disable-multilib
--with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
--enable-libphobos --enable-objc-gc
--with-target-bdw-gc-include=/vol/gcc/include
--with-target-bdw-gc-lib=/vol/gcc/lib/amd64,i386=/vol/gcc/lib
--with-gmp-include=/vol/gcc/include --with-gmp-lib=/vol/gcc/lib/amd64
--with-mpfr-include=/vol/gcc/include --with-mpfr-lib=/vol/gcc/lib/amd64
--with-mpc-include=/vol/gcc/include --with-mpc-lib=/vol/gcc/lib/amd64
--enable-languages=all,ada,obj-c++ --with-isl-include=/vol/gcc/include
--with-isl-lib=/vol/gcc/lib/amd64 --with-zstd-include=/vol/gcc/include
--with-zstd-lib=/vol/gcc/lib/amd64 --build=x86_64-apple-darwin23.2.0
--host=x86_64-apple-darwin23.2.0
The other two are equivalent.
When I check the coarray_40.exe binary on macOS 14, I find:
$ otool -L ./coarray_40.exe
./coarray_40.exe:
@rpath/libatomic.1.dylib (compatibility version 4.0.0, current version
4.0.0)
@rpath/libgfortran.5.dylib (compatibility version 6.0.0, current
version 6.0.0)
@rpath/libgcc_s.1.1.dylib (compatibility version 1.0.0, current version
1.1.0)
@rpath/libquadmath.0.dylib (compatibility version 1.0.0, current
version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 1336.61.1)
$ otool -l ./coarray_40.exe
[...]
Load command 14
cmd LC_LOAD_DYLIB
cmdsize 56
name @rpath/libatomic.1.dylib (offset 24)
time stamp 2 Thu Jan 1 01:00:02 1970
current version 4.0.0
compatibility version 4.0.0
but, unlike for the other libs, *no* corresponding LC_RPATH.
If I manually add the right -B arg
(-B/private/var/gcc/regression/master/14-gcc/build/x86_64-apple-darwin23.2.0/./libatomic/.libs)
to the command line, the missing LC_RPATH shows up and the excutable
runs successfully.
