[Vm-dev] Re: Plugin not available externally so I try to build internally

[Robert Withers]

I found some more info and I am nearing the end of investigation without 
solution.

The 3 plugins under inquiry are DESPlugin, MD5Plugin, and SHA256Plugin. 
These 3 are newly internal from being external all this time the past 9 
years. I don't think I necessarily need header files as the EXPORT 
statements are in the generated .c files.

Here are a few details of these three plugins:
1) there are no .o files
2) there is a .excluded file in each plugin directory in the build 
directory.
3) each .a file is 8 bytes = !<arch>\z
4) only log in mvm output is the following:

ar -rc DESPlugin.a
ranlib DESPlugin.a

So there is no compile statement being run...

hmmmm...I am looking for Makefile.in fragments for the successful 
internal plugins, but I am not finding them. There must be a small 
additional piece, outside squeak, that makes them internal, but it is 
escaping me. I was up all night - I installed Ubuntu at least 7 times 
and Suse twice. I finally went 32-bit os and it works, kinda sorta.

Alright then, Robert
