Re: [Tnfox-discussion] building issue with TnFox 0.89

[Niall D. <s_s...@ne...>]

Hi,

Sorry it's taken so long to get back to you. It turns out that LOTS 
of stuff had become broken and last night I pushed a fairly hefty 
update of source changes to the GIT repos.

It now compiles cleanly on VS2010 and GCC v4.3. However right now it 
segfaults on process init on both Linux and Windows :(

I know what the problem is on Windows (latest changes to nedmalloc) 
but on Linux the segfault happens so early that gdb can't attach 
which is a PITA. I'm hoping the fixes on Windows will fix Linux.

The only major change since the last time it was working on Linux and 
now is nedmalloc, and I suppose rvalue reference support in GCC 
(TnFOX has had rvalue reference support since it was first proposed 
for addition, it was just always #ifdef disabled). Seeing as rvalues 
are working on MSVC properly it could be a bug in this version of 
GCC. I have yet to try force disabling them and seeing if it fixes 
the process init problem.

In other words, I'll get back to you! And my profuse apologies for 
this - I had no idea that TnFOX had become this unmaintained. It was 
working absolutely fine about fourteen months ago when I last ran a 
full test suite on all supported platforms. It's amazing how quickly 
toolsets can suddenly change.
