Hi David,<br>
<br>
I found a major focus of failure but not it's configured cause. Looking<br>
at the generated Makefiles, in the build directory plugin<br>
subdirectories, for a sample plugin and the 3 failure plugins, there is<br>
a significant difference. The 3 failure plugins have no object file<br>
targets, whereas the successful plugins, like SecurityPlugin, has these<br>
targets. I don't know where, why or how, but that is the what of it.<br>
<br>
I'm guessing and looking at the platform/unix/config directory, but it's<br>
complex. Since you had success, it's just a teeny tiny thing in there<br>
that is an issue. Since it is inside the configure phase then it is<br>
those files or a subfile they contact.<br>
<br>
I just tried again with a fresh checkout with the same failure. David,<br>
how have you generate plugins for internal? Did you use the script below<br>
[1]?<br>
</blockquote>
No, I am using the CMake based build (trunk VMMaker, but not relevant for<br>
building a Spur VM). If the plugins work there, then they will also work<br>
for Cog/Spur, although you may need to work out some glitches in the<br>
autotools based build for Cog/Spur.<br>
</blockquote>
<br></span>
Oh, I see, that is fairly different in the configure aspect, I'm guessing.<br>
<br>
I just had a thought and it is building now after I regenerated the vm + internals. The <a href="http://make.int.in" rel="noreferrer" target="_blank">make.int.in</a> fragment which sets the target must only be looking at the 'src' directory for c-files to chew on. Since I generated into the 'spursrc' directory, I am guessing that the fragment missed the target. Let me check...<br>
<br>
Yes! Success on build..but in testing, even though the DESPlugin.a was libtool into vm.a which was statically linked to the squeak binary, it still did not load this plugin when I ran the Crypto tests.<br>
<br>
issues:<br>
1) external: with a dynamic linked DESPlugin, it doesn't load the library<br>
2) internal: configure with <a href="http://make.int.in" rel="noreferrer" target="_blank">make.int.in</a> looks into the src, not spursrc (I am guessing, but it built)<br></blockquote><div><br></div><div>2) is not an issue.

Hi Robert,<br>
<br>
Just to confirm: These plugins can all be compiled either external or<br>
internal, and the primitives do show up when I do "nm -gC". No external<br>
headers are required. I'm using a different build environment, so I<br>
cannot directly answer your questions, but I expect that the issue is<br>
something related to your build setup.<br>
<br>
You might want to double check the plugins.ext, <a href="http://plugins.int" rel="noreferrer" target="_blank">plugins.int</a>, and<br>
plugins.exc files your build directory. Otherwise I can't think what<br>
to suggest.<br>

I found some more info and I am nearing the end of investigation without<br>
solution.<br>
<br>
The 3 plugins under inquiry are DESPlugin, MD5Plugin, and SHA256Plugin.<br>
These 3 are newly internal from being external all this time the past 9<br>
years. I don't think I necessarily need header files as the EXPORT<br>
statements are in the generated .c files.<br>
<br>
Here are a few details of these three plugins:<br>
1) there are no .o files<br>
2) there is a .excluded file in each plugin directory in the build<br>
directory.<br>
3) each .a file is 8 bytes = !<arch>\z<br>
4) only log in mvm output is the following:<br>
<br>
ar -rc DESPlugin.a<br>
ranlib DESPlugin.a<br>
<br>
So there is no compile statement being run...<br>
<br>
hmmmm...I am looking for Makefile.in fragments for the successful<br>
internal plugins, but I am not finding them. There must be a small<br>
additional piece, outside squeak, that makes them internal, but it is<br>
escaping me. I was up all night - I installed Ubuntu at least 7 times<br>
and Suse twice. I finally went 32-bit os and it works, kinda sorta.<br>
<br>
Alright then, Robert<br>

Oh dear, they are exported symbols from th e .a file, but DESPlugin<br>
has no symbols using nm -gC. I am not sure the next step. I am open<br>

I do believe I need to write some header files in<br>
platforms/Cross/plugins for these 3 plugins. I'll give that 3 tries<br>
for 12 points.<br>

I built the vm with crypto plugins external but the running image/vm<br>
cannot find or load them. They are not being used. Therefore, I am<br>
trying to build them internally[1]. After generating them for<br>
internal, I ran around changing the examplePlugins.int/.ext, in<br>
spursrc and src. Under the build.linux32x86/squeak.cog.spur I<br>
changed the real <a href="http://plugins.int/.ext" rel="noreferrer" target="_blank">plugins.int/.ext</a> as well. The crypto plugins make<br>
it on the internal side, but I get an error when I try to link<br>
squeak[2]. The complaint is:<br>
<br>
undefined reference to `DESPlugin_exports'<br>
<br>
I don't recall how the internal plugin exports work. Might anyone<br>
refresh my memory and explain how this all works?<br>

Thank you for all,<br>
