You can either force the port to be compiled with -std=gnu++98 (by adding USE_CXXSTD=gnu++98 to the port Makefile), or change the two instances where these assignments are being done, e.g.: --- src/base/judy/src/judyL2Array.h.orig 2014-12-26 20:12:05 UTC +++ src/base/judy/src/judyL2Array.h @@ -166,7 +166,7 @@ class judyL2Array { kv.value = *_lastSlot; _success = true; } else { - kv.value = ( JudyValue ) 0; + kv.value = nullptr; _success = false; } kv.key = _buff[0]; --- src/base/judy/src/judyS2Array.h.orig 2014-12-26 20:12:05 UTC +++ src/base/judy/src/judyS2Array.h @@ -191,7 +191,7 @@ class judyS2Array { kv.value = *_lastSlot; _success = true; } else { - kv.value = ( JudyValue ) 0; + kv.value = nullptr; _success = false; } kv.key = _buff; -Dimitry [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.2 iF0EARECAB0WIQR6tGLSzjX8bUI5T82wXqMKLiCWowUCWmzyIgAKCRCwXqMKLiCW o9KIAKCL8nnZ9SjFMBPfL81i+jNcniqbQgCeMov2kYTgA64AFu/R3ik6q9w+Ga8= =6I9S -----END PGP SIGNATURE-----help
