Hi Nicolas,

Welcome to VM building :-)

You are not doing anything wrong. The two errors in your log show up as warnings, not errors, when I compile the VM. That probably means two things:

1) There very likely is an existing problem in the source code that should be addressed.

2) Your compiler is choosing to treat this as an error, rather than a warning. Over time we are seeing compilers becoming more strict about enforcing rules like this, so it may be that your system has a newer compiler, or that it is somehow configured by default to use more strict rule enforcement.

I do not have a quick answer for how to work around this problem, but maybe someone who is familiar with compiler flag settings can offer a suggestion.

Hi everyone! My name is Nicolas Sarfati and I am working on my University Final work. For it, I am needing to generate an Image of the VM, but I am not getting lucky. On last step, when it converts the C code to the proper image, it's failing with the next error message: (Attached you can get the full log)

Environment: Linux x64 Manjaro

Kernel: 6.6.19-1-MANJARO

 

These are the steps that I am doing:

1. git clone git@github.com:OpenSmalltalk/opensmalltalk-vm.git
2. I am running the next command: ./scripts/updateSCCSVersions
3. cd image
4. ./buildspurtrunkvmmaker64image.sh || also tried with an specific version like these: ./buildspurtrunkvmmaker64image.sh -vm Squeak6.1alpha-23007-64bit
5. ./buildspurtrunkreader64image.sh
6. I am running the Squeak with the VMMaker image: sqcogspur64linuxht/squeak Spur64VMMaker.image
7. Then inside Squeak, I run some of the commands in the worksapce:
   1. [VMMaker generateAllConfigurationsUnderVersionControl] valueSupplyingAnswer: false.
   2. [VMMaker generateSqueakSpurCog64VM] valueSupplyingAnswer: false.
   3. VMMaker generateVMPlugins.
8. After it finish, I go to the directory: cd building/linux64x64/squeak.cog.spur/build
9. An run the command ./mvm
   1. Is asks if I want to make a clean build, which I answer Y
   2. Then the configure commands outputs all right
   3. But then the build breaks with the message which I paste before.
10. Attached you can get the full log.

Any input will be really appreciated, since I am really stuck!!

 

Thanks!

Nicolas.
