A port of Google V8 JavaScript engine to z/OS Open Tools project

The upstream for v8 is here.

The manual workflow to build v8port requires the following:

• python
  • tested with python 3.11 from base z/OS install
• ninja from z/OS Open Tools ninjaport
• gn from zos open tools gnport
  • clang from IBM C/C for Open Enterprise Languages on z/OS 2.0

  $ clang   --version
  C/C   for Open Enterprise Languages on z/OS 2.0.0, clang version 14.0.0 (build 37a9321)
  Target: s390x-ibm-zos
  Thread model: posix
  InstalledDir: /C/CCplus/LangV2GA/usr/lpp/IBM/oelcpp/v2r0/bin
  

• depot_tools port zos open tools depot_toolsport
• zoslib
  • The manual workflow provides instructions on how to install this. However, its noted here to catalog the compiler. With that said, it uses the same clang above and clang from the same package.

  $ clang --version
  C/C   for Open Enterprise Languages on z/OS 2.0.0, clang version 14.0.0 (build 37a9321)
  Target: s390x-ibm-zos
  Thread model: posix
  InstalledDir: /C/CCplus/LangV2GA/usr/lpp/IBM/oelcpp/v2r0/bin
  

This is the workflow for building v8 using the z/OS Open Tools framework.

1. install depot_tools
   • $ zopen install depot_tools
2. Currently v8port is still in developer form
   • $ cd ${HOME}/zopen/dev
   • $ git clone [email protected]:ZOSOpenTools/v8port.git
3. The build process will use git via ssh. If you have a passphrase for your ssh key, do the following:
   • $ eval \ssh-agent``
   • $ ssh-add ${HOME}/.ssh/some_private_ssh_key
4. Start the build process
   • $ cd ${HOME}/zopen/dev/v8port
   • $ rm -rf ~/.local v8base install ${HOME}/zopen/usr/local/zopen/v8 venv log; zopen build > out.log 2>&1

It will create a venv in ${HOME}/zopen/usr/local/zopen/v8/v8-DEV/venv. The v8port buildenv file will setup config the environment to fetch the v8 source code. Afterwards, source this venv via . ${HOME}/zopen/usr/local/zopen/v8/v8-DEV/venv/bin/activate to work on the repo.

This can be done in a convienece script via

$ . ./setenv.sh

or if you want to preserve the hidden v8base/.gclient and v8base/.gclient_entries

$ . ./setenv.sh -resume
