I'm currently trying to build RDKit 2023_03_1 on Windows 11 with Visual
Studio 2022 Community. The building itself works:
- No errors during the build
- I get a working extension against PostgreSQL 15.2
- I get working static libraries for Visual Studio (RDGeneral.lib etc.)
- I get a rdkit package for Python 3.10
BUT this does not work:
from rdkit import Chem
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\RDKit\lib\site-packages\rdkit\__init__.py", line 6, in <module>
from . import rdBase
ImportError: DLL load failed while importing rdBase: The specified
module could not be found.
Hello again,
I have managed to build the shared objects also by now. I had to carve
this out of the azure pipelines, apparently it only works correctly if
you build like there, i.e. using cmake instead of MSBuild directly.
E.g.
C:\CMake\bin\cmake --build . --config=Release --target install
instead of
& "C:\Program Files\Microsoft Visual
Studio\2022\Community\MSBuild\Current\Bin\MSBuild.exe"
/p:Configuration=Release INSTALL.vcxproj (as the RDKit Book says)
But the rdkit Python package still throws abovementioned error. I did
the same build on Ubuntu, and everything worked out of the box. I have
also checked various "solutions" from the WWW but to no avail. I cannot
see any unresolved dependencies for rdBase.pyd. Any helpful suggestions
or pointers are appreciated.
best regards
Ernst-Georg
