[Vm-dev] Can't build current #3262 cog vm on ubuntu 14 vmware hosted system

Last summer I was using a vmware hosted ubuntu 14.0.4 system to build vms for use in making the ARM cog stuff. Last week I tried to get back to that and I simply can’t make a working vm with the latest ~#3600 code.

The normal vm builds but won’t find the x11 display module - although it does seem to be able to find the null display. Not so terribly helpful though. Obviously the first thing I tried was building a debug vm to see if I could work out what is wrong but that won’t even come close to building. The log is full of exciting things like -
/mnt/hgfs/tim/Documents/Squeak/Rasbian-VM/Pi-CogVM/Cog/src/vm/gcc3x-cointerp.c:579:13: note: previous declaration of ‘markStackPageMostRecentlyUsed’ was here
 static void markStackPageMostRecentlyUsed(StackPage *page) NoDbgRegParms;
             ^
/mnt/hgfs/tim/Documents/Squeak/Rasbian-VM/Pi-CogVM/Cog/src/vm/gcc3x-cointerp.c:18573:1: error: conflicting types for ‘markStackPageNextMostRecentlyUsed’
 markStackPageNextMostRecentlyUsed(StackPage *page)
 ^

and later in the log -
             ^
/mnt/hgfs/tim/Documents/Squeak/Rasbian-VM/Pi-CogVM/Cog/src/vm/gcc3x-cointerp.c:579:13: warning: ‘markStackPageMostRecentlyUsed’ used but never defined [enabled by default]
 static void markStackPageMostRecentlyUsed(StackPage *page) NoDbgRegParms;
             ^

To extra check, I tried the stack vm as well; same problems.

Just to make life really amusing, the Raspbian system builds from the very same files without any problems, both plain and debug. I know it’s the same files because both unix systems mount the directories off my iMac.

I’m at a loss to see why this is happening. Sure, different compilers with different bugs etc, but really?
