After some help from vatic and Craig on IRC, I am able to build something broken

I have been unable to deduce the steps required to build Flow.so under linux. There are guides [1] [2], but ran into problems following each one, such as configure barfing on an empty build directory, where to put the source, whether VMMaker is needed, and whether generated or raw source is required to build Flow.so. So, here is what I am doing. It does not work:

1. Download the 3.9-8 VM source code: http://squeakvm.org/unix/release/Squeak-3.9-8.src.tar.gz
2. Unzip it to /home/tapple/squeak/vm
3. Download the 2a5 Flow source code: http://netjam.org/flow2a5.tar.gz
4. Unzip it to /home/tapple/squeak/vm/platforms/Cross/plugins/FlowPlugin

4.1. Download the Flow build files: http://netjam.org/flow2aPrimitiveSources.zip 4.2. Extract flow2aPrimitiveSources.zip/flow/platformSpecific/linux/Makefile.in to /home/tapple/squeak/vm/platforms/unix/plugins/FlowPlugin

5. Download and run squeak-dev: http://damien.cassou.free.fr/squeak-dev/sq3.9-7067dev07.08.1.zip
6. Install VMMaker-3.8b6.1 from Universes (Category: System)

Don't do step 7:

7. Load "spoonProcessor Changes.st" from the components directory of http://www.movedigital.com/go/netjam/63004/spoon.2a12.linux.zip

This step should not be done, and seems to be the cause of the spurious Flow.c I found last time (see step 9 below). It seems VMMaker is generating bad source for the Flow simulator support

8. Open VMMaker Tool and configure: 8.1. Interpreter Class Name: Interpreter 8.2. Path to Platform Code: /home/tapple/squeak/vm/platforms 8.3. Platform Name: unix 8.4. Path to Generated Sources: /home/tapple/squeak/vm/src 8.5. Internal Plugins: None 8.6. External Plugins: Flow

8.7 should be: External Plugins: None

9. Generate Entire. This generates, among other things, a single file containing the generated Flow source: /home/tapple/squeak/vm/src/plugins/Flow/Flow.c

Flow.c is no longer generated, as it shouldn't be

9.1. add B3DAccelleratorPlugin UnixOSProcessPlugin Flow to the list in plugins.ext

10. In shell: 10.1. cd /home/tapple/squeak/vm/src 10.2. ../platforms/unix/config/configure 10.3. make

I get, in the source directory, an executable named squeak and a Flow.la in Flow. I try running the squeak vm with the spoon image, and I get the following error:

Recursive not understood error encountered

Segmentation fault

I try moving Flow and B3DAcceleratorPlugin to plugins.int. I also notice that I have no plugin named UnixOSProcessPlugin in either my platforms/unix/plugins or platforms/Cross/plugins directories. I look at the size of the compiled UnixOSProcess.la and it seems empty (only 758 bytes). So I delete it from the list of compiled plugins. No matter whether I use UnixProcessorPlugin, or whether plugins are internal or external, I still get the same error whenever I try running the compiled squeak executable.

Also, no .so files are ever compiled, only .la and .a files (for external and internal plugins, respectively)

I may yet figure this out. Thanks for the help

Hi Matthew, hi list,

I've finally got around to trying to build a spoon VM of my own, and I've met with some success (!).

* I've managed to build a VM that can load and run "memory.image" * I get a page at http://localhost:8090/3 * I've build a separate Flow plugin that works with a stock VM well enough to allow the naiad components to load and partially run

I now run into the problem where

Smalltalk at: #ExampleWormholeServer put: (WormholeServer atPort: 9999) succeeds,

ExampleWormholeServer connectToPort: 7777 atHostNamed: 'localhost' succeeds,

but

OtherBrowser openOnWormhole: ExampleWormholeServer clients any fails, with an error

MessageNotUnderstood: Other>>module

The next message will contain the steps I took to build a spoonable VM.

Regards, Tony

Below are my notes from building a VM capable of running memory.image. Note that I ran VMMaker three times - the first two times are not needed! I was just proceeding in small steps to do things like look at diffs etc etc.

Things that puzzle me:

- the calls to halt ("halt(3)" appears a lot in interp.c) - the call to cleanUpContexts - the error generating LargeIntegersPlugin - the nasty code in the generated LargeIntegersPlugin

Regards, Tony

Get http://squeakvm.org/unix/release/Squeak-3.9-8.src.tar.gz Get http://netjam.org/flow2a5.tar.gz Get http://www.netjam.org/flow/releases/current/bits/flow2aPrimitiveSources.zip Get http://damien.cassou.free.fr/squeak-dev/sq3.9-7067dev07.09.1.zip

Unzip sq3.9-7067dev07.09.1.zip somewhere convenient. - Untar Squeak-3.9-8.src.tar.gz into the resulting sq3.9-7067dev07.09.1 directory. - Unzip spoon.2a12.linux.zip as well - Unzip flow2a5.tar.gz, and rename "flow/" to "flow2a5/" - Unzip flow2aPrimitiveSources.zip, and rename "flow/" to "flow2a/"

Edit flow2a/platformSpecific/linux/Makefile.in, commenting out the "cp Flow.so $(plgdir)" line.

Open the image in the sq3.9-7067dev07.09.1 directory.

Open Package Universe Browser - Choose "--System--", "VMMaker", "3.8b6.1" - Middle-click "3.8b6.1", choose "select this version" - Click "install selection"

Much code downloading and installation happens.

Open VMMaker - click "Find Path" at the end of the "Path to platforms code" line - Choose your current working directory's subdirectory "Squeak-3.9-8". - Click OK - Click "Find platform" on the "Platform name" line. - Choose "unix" from the menu that appears. - Click "Core+Internal" on the "Generate" line - When it's done, save and quit the image

Rename away the generated source directory: $ mv src32 src32-without-patches

Reopen the Squeak-Dev image. File in "./spoon/components/spoonProcessor Changes.st" Click "Core+Internal" again. Save and quit the image again.

Rename the generated source directory appropriately: $ mv src32 src32-with-patches

If you like, examine the core changes to the interpreter: $ diff -w -ru3 src32-without-patches/ src32-with-patches/

Regenerate the VM one more time, with as many plugins as possible external, and the rest internal. - open the image - middle click "Plugins not built" in the VMMaker - choose "make all external" - drag "LargeIntegersSimulator" out of the "External Plugins" panel into the "Plugins not built" panel - click "Entire" - You get an error during LargeIntegersPlugin! Click "proceed". Save and quit the image.

Edit src32/vm/interp.c - add the line "#define halt(x)" to the top - search for the line "cleanUpContexts();" and comment it out

Now apply the changes to the VM sources and build the VM. $ rm -rf Squeak-3.9-8/platforms/unix/src $ rm -rf Squeak-3.9-8/platforms/unix/src32 $ rm -rf Squeak-3.9-8/platforms/unix/src64 $ mv src32 Squeak-3.9-8/platforms/unix/src $ mv Squeak-3.9-8/platforms/unix/src/plugins/Flow/ Flow-plugin-as-generated $ cp -r flow2a5 Squeak-3.9-8/platforms/unix/plugins/Flow $ cp flow2a/platformSpecific/linux/Makefile.in Squeak-3.9-8/platforms/unix/plugins/Flow/ $ mkdir Squeak-3.9-8/build $ (cd Squeak-3.9-8/platforms/unix/config/; make) $ (cd Squeak-3.9-8/build/; ../platforms/unix/config/configure --prefix=/opt/spoon)

Fix LargeIntegers.c line 1370 - comment out the line halt(,("missing primitive: ", primitiveName));

$ (cd Squeak-3.9-8/build/; make) $ (cd Squeak-3.9-8/build/; make install)

Now /opt/spoon/bin/squeak memory.image should work.
