Dear all,
I need help please. I’m compiling a C/C++ code base with clang++ compiler
installed via MacPorts. When I look at the libraries my executable relies on I
see:
otool -L <exe_file>
/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version
1300.36.0)
However, when I try to find out what package owns this library:
sudo port provides "/usr/lib/libc++.1.dylib"
/usr/lib/libc++.1.dylib does not exist.
Further inquiry with ‘pkgutil’ doesn’t shed more light either:
pkgutil --file-info "/usr/lib/libc++.1.dylib"
volume: /
path: /usr/lib/libc++.1.dylib
Would you please tell me, who is the mysterious owner of the ‘libc++’?
Looking for libc++ in the names of ports returns the following list:
sudo port search libc++
gcc-devel-libcxx @13-20230226_1 (lang)
libc++ header implementation to be used by gcc-devel
gcc10-libcxx @10.4.0_5 (lang)
libc++ header implementation to be used by gcc10
gcc11-libcxx @11.3.0_6 (lang)
libc++ header implementation to be used by gcc11
gcc12-libcxx @12.2.0_4 (lang)
libc++ header implementation to be used by gcc12
libcxx @5.0.1_5 (lang)
libc++ is a new implementation of the C++ standard library with support for
C++11 and portions of C++14.
macports-libcxx @11.1.0 (lang)
provides a newer libc++ from llvm for older systems
Found 6 ports.
