Hmm. This code
#ifdef HAVE_DEF_PATH_MAX
char linkbuffer[PATH_MAX + 1];
ssize_t const nRead = ::readlink(encoded.c_str(),
linkbuffer, sizeof(linkbuffer) - 1);
if (nRead <= 0)
return false;
linkbuffer[nRead] = '\0'; // terminator
#else
is specifically protected by the #ifdef, which should be telling us
whether PATH_MAX is defined in limits.h. Which it presumably is on your
system. I wonder if limits.h isn't getting pulled in for some reason.
You could try adding:
#include <limits.h>
to support/filetools.cpp.
