| sf-slack | <mkurc> @litghost: It seems that https://github.com/SymbiFlow/symbiflow-arch-defs/pull/1077 didn't fix libxml for me. I've double checked that conda installed the correct package and it did. | 15:02 |
| tpb | Title: Pin libxml2 to version with fix. by litghost · Pull Request #1077 · SymbiFlow/symbiflow-arch-defs · GitHub (at github.com) | 15:02 |
| litghost | How did you test it? | 15:03 |
| sf-slack | <mkurc> Removed the build directory and started from scratch | 15:03 |

| sf-slack | <mkurc> After manually re-building and installing according to #1066 it worked correctly | 15:07 |
| sf-slack | <mkurc> And this is the same error I encountered for libxml before #1077 when trying full xc7a50t graph the first time | 15:08 |
| litghost | Did you run "all_conda" after cleaning the build dir? This could be a cmake dependency error | 15:09 |
| sf-slack | <mkurc> No, I didn't. But when running single threaded make there are no issues | 15:09 |
| sf-slack | <mkurc> And then I verified version installed | 15:10 |
| sf-slack | <mkurc> and it was correct, as specified in the cmake file: 2.9.9 h14c3975_5 | 15:10 |
| litghost | Huh | 15:12 |

| sf-slack | <mkurc> Well, actually only the one inside conda env should be relevant. | 17:45 |
| sf-slack | <mkurc> When I run `conda list` it reports `libxml2 2.9.9 h14c3975_5 symbiflow` | 17:45 |
| litghost | Can you check if you have an enviroment variable "PYTHON3" defined? | 17:46 |
| sf-slack | <mkurc> outside conda env no. | 17:46 |
| litghost | Also run the python file from https://github.com/SymbiFlow/symbiflow-arch-defs/files/3713720/repo_lxml.py.zip using conda, e.g. | 17:46 |
| litghost | /home/mkurc/Repos/google-symbiflow-arch-defs-2/build/env/conda/bin/python3 repo_lxml.py | 17:46 |
| litghost | Do you have PYTHONPATH defined? | 17:48 |
| litghost | Also run: | 17:49 |
| litghost | conda/bin/python3 -c "import lxml; print(lxml.__file__)" | 17:49 |
| litghost | conda/bin/python3 -c "import lxml.etree; print(lxml.etree.__file__)" | 17:49 |
| sf-slack | <mkurc> The two last commands output paths pointing to files inside the conda env: | 17:51 |
| sf-slack | <mkurc> `build/env/conda/lib/python3.7/site-packages/lxml/__init__.py` | 17:52 |
| sf-slack | <mkurc> and `/build/env/conda/lib/python3.7/site-packages/lxml/etree.cpython-37m-x86_64-linux-gnu.so` | 17:52 |
| sf-slack | <mkurc> no PYTHONPATH outside conda env | 17:52 |
| litghost | Try to see if "conda/bin/python3 repo_lxml.py" works or fails | 17:53 |
| litghost | It will take a couple minutes (~10 on my machine) | 17:53 |
| sf-slack | <mkurc> I'm already doing it | 17:53 |
| litghost | k | 17:53 |
| sf-slack | <mkurc> @litghost: Ok, the repo_lxml.py test completed without errors. | 17:55 |
| litghost | Ok, then the libxml2 in the tree has the fix | 17:55 |
| sf-slack | <mkurc> I guess I must have had something wrong with the conda env | 17:55 |
| litghost | Not neccarility | 17:56 |
| litghost | Run "make VERBOSE=1 file_xc7_archs_artix7_channels.db" | 17:56 |
