Leptonica - Link Error about sw

[egorpugin]

Oh, yes, sorry. Couple of paths were unfixed.
sw --self-upgrade and try now. I've updated binaries.

[rweldin]

No problem. Very appreciative of the work you are doing. Everything worked great after upgrading.

Egor, I'm also having linker issues with Tesseract as noted below. This may be a separate issue and I can open a new issue if you'd prefer, but it appears to be very similar. The simddetect.obj file causing the issue is located at: E:\src\repo\tesseract-master\win64\libtesseract.dir\Release, but Visual Studio is looking in E:\src\repo\tesseract-master\win64.

If you need anything else please let me know.

On a side note when looking at the Additional Dependencies section in Visual Studio for my libtesseract project there were 14 duplicate entries. This likely has nothing to do with this linker issue and may not be a problem, but I thought I would point it out.

[egorpugin]

Yes, I also observed that. Someone changed tess files without fixing tess build. I'll check.

Upd.: this post is about build issue.

Where do you see it? I see only unique libs.

tess build error

1. Can you open an issue on tesseract side? Sse/avx/fma code is not very well set in cmake build. I'm not sure how to better fix it (flags etc.). Implementers should know better.
2. You can try to use sw build of tess.

[rweldin]

I'll open an issue with the Tesseract group.

Regarding the dependencies issue I was looking at the Additional Dependencies string under the Linker > Input options. I used Excel to split the string and sorted it which you can see below. When viewing through the Edit section the true duplicates are removed, but my screenshots below contain libs of the same name that are in different build folders; I don't see that in your screenshot.

I see.
I don't want to investigate this deeply, but I'll keep it in mind.

[egorpugin]

See tesseract-ocr/tesseract#2986 about cmake error.

[rweldin]

Thanks Egor, sorry I didn't have a chance to look into this issue yesterday or make a post.
