Hi, Perhaps my fault - It wasn't that easy to just define YY_NO_UNISTD_H to make graph compile with vc7.1. The problem is that two non-ANSI C functions is called: b->yy_is_interactive = file ? (isatty( fileno(file) ) > 0) : 0; A little documentation search on Win32 gives: <io.h> int _isatty(int); <stdio.h> int _fileno(FILE*); As for how to solve these non-portable stuff with perhaps some BOOST defines, I think you all know better than I do.

Were you able to check it on VC 7.1?
No. I'd appreciate if you could try there.
I'll try to do so later.
We'll deprecate it in 1.32.0 (when, hopefully, we will have a new GraphViz parser that works well) and remove it afterwards.
How the new parser will be implemented?
Spirit.
Is it written yet? Would be interesting to see.
I think the parser is written but the semantic actions are not, so it isn't functional yet. We're trying to unify on some kind of system for dynamic properties, so that we can deal with reading in arbitrary vertex/node attributes. I have a GraphML parser that handles dynamic properties, which hopefully will also work well in the new GraphViz parser. If I get some time post-1.32.0 (hah!), we'll try to get all those bits in.
Granted, they've dropped support for older, broken compilers, so someone will still be getting hurt by this.
Right. OTOH, I start to wonder if BGL should drop support for old compilers as well. (borland and vc6 are marked unusable already). There seem to be a lot of workaround inside BGL which means even reading the code hard.
We promised to keep the parts of the BGL needed for the Python lib in working order. But I've marked borland and vc6 unusable because they've never really been usable and are a huge maintenance burden.
