But the more serious issue is that the configure in VMMaker is only suitable<br>
for linux. I guess that the right thing to do for FreeBSD is to run make in<br>
platforms/unix/config to generate a FreeBSD-specific configure. But I'm out<br>
of my depth when it comes to autoconf.<br>

Note that Ian moved to CMake for the unix builds, so autoconf is no longer<br>
used for building from the SVN trunk. In addition, Geoffroy Couprie has<br>
developed this further such that the VM can be built for both unix and<br>
Windows targets, see thread here:<br>

It's up to Ian and Andreas to say if they want to pursue this direction,<br>
but if you need the Cog build process to be more platform independent<br>
this would be a good thing to consider.<br>

Personally, I'll be moving the Windows build back into MS land. All the reasons for using the MingW/GCC tool chain are gone by now:<br>
* Availability of the tool chain: There have been free versions of MSVC for years now, so this is no longer an issue.</blockquote><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
* Performance of the VM: With the JIT, the performance difference between the compilers no longer matters.<br>
* Size of difficulty of the install: New versions of MingW are no easier to install than Cygwin or other monsters.<br></blockquote><div>MSYS is not that hard to install. And GCC can be use to cross compile, which is really useful for tests, continuous integration, etc.</div>

<br>
On the other hand, there are some exceptionally good reasons to use MSVC:<br>
* Debugging: Did you know that MSVC now has seemless in-place editing? When I worked on SqueakSSL, I was shocked to find that an access violation was simply presented as a break point and after fixing it the compiler patched the code in place without restarting Squeak, and it worked!<br>
* Up-to-date headers and libraries: SqueakSSL wouldn't compile on *any* version of MingW or Cygwin due to the absence / lack of correctness of the headers and missing libraries even though the APIs are 5+ years old.<br>
</blockquote><div>Did you check the recent headers? Most of the recent API (XP/Vista) are in the actual MinGW headers. The DirectX headers are a bit old, but considering you're using DirectX 7, I don't think that's an issue. What specific headers/libraries/functions are you talking about?</div>
<div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
* Consistent use of runtime libraries: For some external linkage, having the latest MSVC platform libraries available is important.<br>
<br>
At this point the advantage is clearly with the MS tool chain and the only hurdle is that I'll have to update all the makefiles etc.<br></blockquote><div> Well, here goes my shameless advertisement: CMake could be used to generate Makefiles for MSVC :)</div>
<div>I think it would still need to be fixed though, but that's less work to do.</div><div><br></div><div>Anyway, do you think you could keep the code compatible with GCC? I could take care of the header fixes.</div>
