Install Issue #62

Closed atkinsr57 closed 2 years ago

atkinsr57 commented 2 years ago

I run into the following error when installing pidng:

_Creating library build\temp.win-amd64-3.8\Release\src/pidng\ljpegCompress.cp38-win_amd64.lib and object build\temp.win-amd64-3.8\Release\src/pidng\ljpegCompress.cp38-win_amd64.exp lj92.obj : error LNK2001: unresolved external symbol __builtin_clz build\lib.win-amd64-3.8\ljpegCompress.cp38-winamd64.pyd : fatal error LNK1120: 1 unresolved externals error: command 'C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Tools\MSVC\14.32.31326\bin\HostX86\x64\link.exe' failed with exit status 1120

Same error on 2 different W'10 machines with different versions of VC. Any help resolving this would be appreciated as I am a hardware guy. FYI we are told the conversion works for the Luxonis OAK-1 camera as well.

Thanks, Bob

I do not have any immediate fix you can perform to solve this on Windows. I would recommend Linux installation if you can make that accomodation.

It is an issue with an underlying C library and the compilation is failing in a Windows environment.

Thank you - works as described in a Linux environment

I'm also getting this issue, but tbf I'm only interested on writing DNGs and setting up Linux is too much of a hassle. Can I strip all the C code and still make it work? Or is the C code required to write DNGs?

The C Code is present for Lossless Compression. If you know how to omit the c code yourself, then yes it shouldn't affect the rest of the library otherwise.
