So any ideas?

I tried to build the CogVM.

• search for build instructions, blog post, etc.
• almost give up in frustration before discovering the process noted below

:)

• download the tar ball from:

https://ci.lille.inria.fr/pharo/view/Cog/job/Cog-VM/Architecture=32,OS=mac/

• find and install cmake
• already had a C compiler installed
• the HOWTOBUILD file said: cd build cmake . make
• the build path is hard coded so:

yes, this is an unavoidable outcome of being able to specify custom paths by developer for sources/build directories.. they are written into directories.cmake file. Initially all paths there was relative, but since user can specify own (absolute) custom paths, there is no way how it can keep working using relative paths.

You can edit this file, or you can just run an image placed in ./image subdirectory and rerun cmake files generation on you machine, so paths will be fixed automagically.

% mkdir -p Users/hudson/jenkins/workspace/Cog-VM/Architecture/32/OS/mac/ % mv ~/src Users/hudson/jenkins/workspace/Cog-VM/Architecture/32/OS/mac/cog # where ~/src is the un-tar'ed tar ball from above

• run cmake and make again (sometimes had to remove CMakeCache.txt file)
• build fails at:

==== [ 77%] Building CXX object CMakeFiles/CogVM.dir/Users/hudson/jenkins/workspace/Cog-VM/Architecture/32/OS/mac/cog/platforms/iOS/vm/Common/Classes/sqSqueakScreenAndWindow.m.o In file included from /Users/hudson/jenkins/workspace/Cog-VM/Architecture/32/OS/mac/cog/platforms/iOS/vm/Common/Classes/sqSqueakScreenAndWindow.m:44: /Users/hudson/jenkins/workspace/Cog-VM/Architecture/32/OS/mac/cog/platforms/iOS/vm/OSX/SqueakOSXAppDelegate.h:46: error: cannot find protocol declaration for ‘NSApplicationDelegate’ make[2]: *** [CMakeFiles/CogVM.dir/Users/hudson/jenkins/workspace/Cog-VM/Architecture/32/OS/mac/cog/platforms/iOS/vm/Common/Classes/sqSqueakScreenAndWindow.m.o] Error 1 make[1]: *** [CMakeFiles/CogVM.dir/all] Error 2 make: *** [all] Error 2 ====

• the culprit is the line:

@interface SqueakOSXAppDelegate : sqSqueakAppDelegate

<NSApplicationDelegate> - web search for NSApplicationDelegate - find Apple dev page that says: NSApplicationDelegate - Available in OS X v10.6 and later.

So, is there an important reason to use NSApplicationDelegate? IIUC, it results in the VM requiring OSX 10.6 or higher, which means my 10.5.8 will never work with CogVM's built this way.

is there a reason why you cannot upgrade your OS?
