[Mono-devel-list] Trouble building Mono 1.0.2 on Solaris 7

[Trevor Dennis]

Hello,

I'm running into some trouble trying to build Mono 1.0.2 on a Solaris 7 
system.  It appears that some patches were applied in the last few 
months that are making use of a mmap parameter, MAP_ANON or 
MAP_ANONYMOUS.  Apparently Solaris 7 and below do not have this 
capability (Or I am unaware of a patch that adds them).

Here is the output from make.

A quick search shows that it is used in these locations.

OPT_MAP_ANON,



Is there an option to configure to get the build to revert back to the 
older malloc implementation?  I went with the defaults that configure 
chose.  I also tried --disable-shared-handles but that does not help.  
I've also tried mono-1.1.1 and it gets the same errors (on line 203 though).

Is this fixable or is Solaris 7 not going to be supported going forward? 

Thanks,

Trevor.
