Dear All,
I've run into an issue twice in the last days, so I wanted to kindly ask
for your input. Two packages I want to use are gRPC (the Google cross
platform RPC library) and boost::filesystem, and both require _WIN32_WINNT
to be defined to at least 0x0600. boost::filesystem seems to support sym-
links only when _WIN32_WINNT is defined to at least 0x0600. I did not delve
deeply into this, but that was my take from the following report, and I've
been plagued by the same issue:
http://stackoverflow.com/questions/19471266/boostfilesystemcreate-symlink-not-supported
Is _WIN32_WINNT defined by default? If yes, by whom (MSYS2, or MinGW64 gcc)?
If its not defined by default, should packages set it via CFLAGS, or is there
a good policy how I can compile for a specific Windows version (Vista / newer)?
Would it maybe make sense to set 0x0600 (Vista) as a default, in order to
enable "modern" things like symlinks? Or are there still XP users left? :-)
Cheers,
Mario
