Deb’s Notes on BrainGenix installation

BrainGenix-API

• Cloning the repository takes unnecessarily long. Can this be cut down?
• Setup.sh
  • apt not installed error for Setup.sh. Should add dnf support. -> Added to local copy of Setup.sh.
    • Also list supported distributions with versions.
  • Error: Unable to find a match: binutils-dev libunwind-dev libdwarf-dev libdw-dev. Find equivalents for dnf. -> Added to local copy of Setup.sh.
  • TODO: Should I commit my local version to the API repo?
• Build.sh
  • Runs without a hitch (on my machine :)).
• Run.sh
  • Error: lib/libstdc++.so.6: version GLIBCXX

3.4.32' not found. I am using an older version of GCC. - Specify minimum GCC version somewhere? Either in CMakeLists.txtorBuild.sh? - Add instructions to set environment variables CCandCXXto whatevergccversion works and is installed in the user's system. E.g. ```bash export CC=/usr/bin/gcc-10 export CXX=/usr/bin/g++-10 ``` - If user has multiplegccversions, make a symlink to the version oflibstdc++.so.6that supportsGLIBCXX

3.X.YZ`. E.g. bash sudo ln -s /usr/lib64/libstdc++.so.6 /path/to/current/libstdc++/checked - Error: PyBind pybind11::handle::inc_ref() is being called while the GIL is either not held or invalid. Please see <https://pybind11.readthedocs.io/en/stable/advanced/misc.html#common-sources-of-global-interpreter-lock-errors> for debugging advice. If you are convinced there is no bug in your code, you can #define PYBIND11_NO_ASSERT_GIL_HELD_INCREF_DECREF to disable this check. In that case you have to ensure this #define is consistently used for all translation units linked into a given pybind11 extension, otherwise there will be ODR violations. The failing pybind11::handle::inc_ref() call was triggered on a module object. terminate called after throwing an instance of 'std::runtime_error' what(): pybind11::handle::inc_ref() PyGILState_Check() failure. ./Run.sh: line 7: 11424 Aborted - TODO: Debugging needed. See this

• Instructions to package on the website are unnecessary, as only developers would be interested in doing so.

## BrainGenix-NES

• Cloning the repository takes unnecessarily long. Can this be cut down?
• Setup.sh
  • Smooth installation of dependencies. dnf cannot find a few dependencies (Error: Unable to find a match: libvulkan-dev vulkan-validationlayers-dev libxcb-xfixes0-dev libx11-dev libxrandr-dev)
• Build.sh
  • Error:
