Just follwing your script but I'm getting the error "No package 'lept' found"

Please can you help me? leptonica-1.78.0d.lib is available in /LIBPATH:"C:\tempo\vcpkg\installed\x86-windows\debug\lib"

What version of Tesseract source are you using? Looks like there may have been some breaking changes since I wrote the notes.

git checkout -b 4.1.0 4.1.0

Okay, ill check it out when I can. Probably this weekend.

Note that the method I use and is described on the wiki only uses vcpkg to build leptonica, not Tesseract. Which is probably why it didn't find the vcpkg version of leptonica.

It should however have found the version of leptonica you built first unless they changed the lib name or something.

@charlesw, did you find the bug?

charlesw commented 4 years ago

No the instructions provided worked fine for me using the following versions of the library leptonica 1.79 and tesseract 4.1.0.

I had a quick look at your cmake log and it doesn't appear to be complete so not sure what you specific issue is however I suspect it's environmental. Just to be clear the environment I'm using is the following:

The general gist is that leptonica is built using vcpkg to provide the dependent image libs (libtiff etc), while tesseract is built without without vcpkg and so should find leptonica version you just built by looking in the directory specified by the -DCMAKE_INSTALL_PREFIX option.

I'm also assuming your using the instructions outlined here: https://github.com/charlesw/tesseract/wiki/Compiling-Tesseract-and-Libleptonica-(using-vcpkg)

charlesw commented 4 years ago

Actually there has been some changes in leptonica 1.79 and tesseract 4.1.1, working on preping a release over the next couple days time permitting. Will release some updated instructions then however the instructions should have worked as is for 1.78 and 4.1.0.

Stay tuned...

👍 Thanks

Yes, I'm using your link https://github.com/charlesw/tesseract/wiki/Compiling-Tesseract-and-Libleptonica-(using-vcpkg)

In my case, pkgconfig just couldn't find the compiled lept. I tried pkg-config --list-all and lept wasn't in the list. Having set PKG_CONFIG_PATH=C:\your\path\to\installed\build\x64\lib\pkgconfig helped me solve the problem.
