4.11.0 Installation error: fatal error C1083: Cannot open include file: 'simdutf.h': No such file or directory

src\cpp_odbc\level2\level1_connector.cpp(24): fatal error C1083: Cannot open include file: 'simdutf.h': No such file or directory

Is there a solution to this? Thanks in advance for answering...

It seems difficult to find packages for simdutf8. There are currently no Debian packages but fortunately I’m using Nix which has one. Building from source is also an option.

Hey @rupurt,

Do you have any info/docs on how to do that?

I've got turbodbc 4.5.10 working great on Python 3.11.1 with Boost 1_81_0.

Trying to upgrade to newest Python (3.12.3 / Windows 64-bit) with Boost 1_85_0, to turbodbc 4.11, I get the same error as @Bopsie. I also upgraded the VS Build Tools versions thinking that would help, but it didn't.

@swolfe2 I manually pulled out the headers and DLL from the fedora package and vendored it in my repo

Same issue here; the build tutorial doesn't mention where to get simdutf from, how to build it and where to put it. I tried building the latest amalgamation by hand and putting the header in .pyenv/include and the compiled lib file in .pyenv/PCBuild/amd64, but that's giving me simdutf external symbol resolution errors, so I'm probably doing the compilation wrong anyway.

# From the VS Developer Command Prompt
cl.exe /c /nologo /O2 /W3 /GL /DNDEBUG /MD "/Tpsimdutf.cpp"  "/Fosimdutf.obj"
lib.exe "/out:simdutf.lib" "simdutf.obj" /verbose

@swolfe2 I am also facing similar issue while installing turbodbc. Were you able to find a solution for your issue?

[sm-Fifteen]

The only way I've found of making turbodbc work on my end is to cap the version to 4.9 (compatible with pyarrow<=14), which is the last one that didn't use simdutf. Not sure about Python 3.12 support, though, since it's not listed in the changelogs as having had support added in any release.

@xhochy: It doesn't look like the installation instructions have been updated since simdutf became a dependency, and there are no precompiled wheels on PyPI. How is one supposed to install turbodbc now?

[devinrsmith]

It would be great if binary wheels were distributed on PyPi. I see that binary formats are distributed on anaconda.
