After rebasing, my local LLDB builds have again broken because it goes looking for the wrong Python DLL. I'm searching through git logs, but I'm not seeing a related change.
Does anyone know what causes CMake to get confused about which Python versions are installed? LINK : fatal error LNK1104: *cannot open file 'python37_d.lib'* Why is it looking for 3.7? My CMake command uses every hint I know about to ensure that it finds Python 3.8: cmake -GNinja -DLLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN=ON -DCMAKE_BUILD_TYPE=Debug -DLLDB_TEST_DEBUG_TEST_CRASHES=1 -DPYTHON_HOME="C:\Program Files\Python*38*" -DLLDB_PYTHON_HOME="C:\Program Files\Python*38*" -DPython3_ROOT_DIR="C:\Program Files\Python*38*" -DPython3_FIND_REGISTRY=LAST -DLLDB_TEST_COMPILER=D:\src\llvm\build\ninja_dbg\bin\clang.exe ..\..\llvm-project\llvm -DLLVM_ENABLE_ZLIB=OFF -DLLVM_ENABLE_PROJECTS="clang;lld;lldb;clang-tools-extra;compiler-rt" My environment doesn't reference any other version of Python: D:\src\llvm\llvm-project>set | find /I "python" Path=C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\VC\Tools\MSVC\14.24.28314\bin\HostX64\x64;C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\VC\VCPackages;C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\CommonExtensions\Microsoft\TestWindow;C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer;C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Current\bin\Roslyn;C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Team Tools\Performance Tools\x64;C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Team Tools\Performance Tools;C:\Program Files (x86)\Microsoft Visual Studio\Shared\Common\VSPerfCollectionTools\vs2019\\x64;C:\Program Files (x86)\Microsoft Visual Studio\Shared\Common\VSPerfCollectionTools\vs2019\;C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x64;C:\Program Files (x86)\Windows Kits\10\bin\x64;C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\\MSBuild\Current\Bin;C:\Windows\Microsoft.NET\Framework64\v4.0.30319;C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\;C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\Tools\;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Windows\corpam;C:\Windows\ccmsetup;C:\Program Files\Git\cmd;C:\Program Files\Git\usr\bin;D:\src\util\GnuWin32\bin;C:\Program Files\doxygen\bin;C:\Program Files\Notepad++;D:\src\llvm\build\ninja_dbg\bin;D:\src\llvm\llvm-project\clang\tools\clang-format;C:\Program Files\Python38;D:\src\llvm\llvm-project\llvm\utils\git-svn\;D:\src\util;D:\src\util\swigwin-3.0.12;C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin;C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\CommonExtensions\Microsoft\CMake\Ninja __VSCMD_PREINIT_PATH=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Windows\corpam;C:\Windows\ccmsetup;C:\Program Files\Git\cmd;C:\Program Files\Git\usr\bin;D:\src\util\GnuWin32\bin;C:\Program Files\doxygen\bin;C:\Program Files\Notepad++;D:\src\llvm\build\ninja_dbg\bin;D:\src\llvm\llvm-project\clang\tools\clang-format;*C:\Program Files\Python38* ;D:\src\llvm\llvm-project\llvm\utils\git-svn\;D:\src\util;D:\src\util\swigwin-3.0.12 D:\src\llvm\llvm-project>where python C:\Program Files\Python38\python.exe D:\src\llvm\build\ninja_dbg>which python /c/Program Files/Python38/python I do not have 3.7 on my machine. For a long while now, I've had to keep exactly one version of Python on my machine specifically to prevent LLDB builds from trying to mix versions. But I'm stumped once again. Clues appreciated, Adrian.
