I'm trying to build the signals2 docs for the PDF doc distribution, but I'm failing with: warning: failed to load external entity "hello_world_def_code_snippet.xml" tutorial.xml:50: element include: XInclude error : could not load hello_world_def_code_snippet.xml, and no fallback was found warning: failed to load external entity "hello_world_single_code_snippet.xml" tutorial.xml:52: element include: XInclude error : could not load hello_world_single_code_snippet.xml, and no fallback was found warning: failed to load external entity "hello_def_code_snippet.xml" tutorial.xml:63: element include: XInclude error : could not load hello_def_code_snippet.xml, and no fallback was found etc... I can see that process_snippets.exe is being invoked, but I can't find the output xml files anywhere. This occurs if I either build from within the doc/pdf directory, or the libs/signals2/doc directory. Any ideas? Thanks, John.
