_nanosvg.obj : error LNK2001: unresolved external symbol _PyGen_Send reported when building wxPython on Python 3.10 #2016
Comments
Thanks, this seems to be fixed in newer Cython, see #2017 |
When is this fix merged to mainline branch and released? |
Whenever @RobinD42 re-emerges and gets back to working on wxPython again. |

OS: Windows 10 64bits
I am trying to install wxPython for Python 3.10.
MSVC build tool v14
Operating system:
Python 3.10 64 bit
wxPython 4.1.1
Creating library build/wxsvg\temp.win-amd64-3.10\Release\wx/svg_nanosvg.cp310-win_amd64.lib and object build/wxsvg\temp.win-amd64-3.10\Release\wx/svg_nanosvg.cp310-win_amd64.exp
_nanosvg.obj : error LNK2001: unresolved external symbol _PyGen_Send
build\wxsvg\lib.win-amd64-3.10\wx\svg_nanosvg.cp310-win_amd64.pyd : fatal error LNK1120: 1 unresolved externals
error: command 'C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.29.30133\bin\HostX86\x64\link.exe' failed with exit code 1120
Command 'C:\Python3.10\python.exe setup-wxsvg.py build_ext --inplace' failed with exit code 1.
after searching the wxPython code:
wx/svg/_nanosvg.c:20946: ret = _PyGen_Send((PyGenObject*)yf, value == Py_None ? NULL : value);
wx/svg/_nanosvg.c:20951: ret = _PyGen_Send((PyGenObject*)yf, value == Py_None ? NULL : value);
wx/svg/_nanosvg.c:21035: ret = _PyGen_Send((PyGenObject*)yf, NULL);
According to Python forum, the _PyGen_Send is replaced by PyIter_Send().
Maybe wxPython should check Python version to determine which function is called, PyIter_Send or PyGen_Send()
Thanks/Gavin
