So fdatasync is nonexistent on OS X, and the precompiler is told to treat it as just fsync
#ifdef __macos__
...
src/XrdSys/XrdSysPlatform.hh:#define fdatasync(x) fsync(x)
BUT, the compiler in 10.6 seems to hate the fact that fsync is double-defined.
XrdPosixPreload.cc: In function 'int fsync(int)':
XrdPosixPreload.cc:265: error: redefinition of 'int fsync(int)'
XrdPosixPreload.cc:159: error: 'int fsync(int)' previously defined here
To work around it, commented out the lines
(line 161 or so)
/*
extern "C"
{
int fdatasync(int fildes)
{
static int Init = Xunix.Init(&Init);
return XrdPosix_Fdatasync(fildes);
}
}
*/
and got the build to work again. This looks like it needs to be precompiler-wrapped.
Running off the dev version posted on the web page (20100315-1007)
