Comment (by jvianalopes):

 Installing the hdf5 with

 * sudo port -v install hdf5 +gcc14 +cxx +hl
 configure.cxx_stdlib="libstdc++"

 Looking to the config.log file I see

 * LDFLAGS='-L/opt/local/lib -Wl,-headerpad_max_install_names
 -stdlib=libc++
 -Wl,-syslibroot,/Library/Developer/CommandLineTools/SDKs/MacOSX15.sdk
 -arch arm64'

 I believe the problem is in the option -stdlib=libc++

 Installing hdf5 with:

 * sudo port -v install hdf5 +gcc14 +cxx +hl
 configure.cxx_stdlib="libstdc++" \

   configure.ldflags="-L/opt/local/lib -Wl,-headerpad_max_install_names
 -Wl,-syslibroot,/Library/Developer/CommandLineTools/SDKs/MacOSX15.sdk
 -arch arm64"

 I can compile it without problems.

 Is there a way of removing the "-stdlib=libc++" from the LDFLAGS?
