Fresh build: tesseract not found using pkg-config #312
Comments
|
This is my tesseract.pc file |
I'd be more interested to know what this one says. |
|
My lept.pc To get you a config.log I'll have to run another build first. Next time I'll add the text. I attached the file because I wanted to keep the post short. No problem if you rather want the plain file. |
|
Can't run the build now because SF seems down again. Will do ASAP. |
|
Started a fresh build. Now it fails when creating leptonica. |
Do you want to compile FFmpeg with LibTesseract at all? If not, then you can disable it all together: --- cross_compile_ffmpeg.sh.bak 2018-03-04 17:45:06.406250000 +0100

That's obviously because you haven't compiled LibJPEG at all. And I now see this: build_libtiff() {

I do not need OCR so I could remove libtesseract. I already did and was able to compile everything (both win32/64 and low/high bit depth). Next I'll apply your patch and try again. Normally I would build whatever the script does by default and only add whatever I specifically need. Or remove whatever hurts. :) The problem with patches is that I use Jenkins and rebuild automatically whenever there's a change. When I patch the script I need to reapply the patches everytime changes arrive as they would get overwritten. |
|
Applied the patch and started a new build. Unfortunately libvfilter fails: |
|
I have no idea where this is coming from. I don't understand how something totally unrelated to Tesseract like an audio filter could suddenly fail from this. |
|
I also don't know either why libavfilter would fail. I replaced |
|
In search for the reasons why this started I found that this may be because there was a symbolic link to the build directories. I created that quite a while ago (half a year or so) and it was never a problem. Havoc just started when Sourceforge developed problems and I did a "rm -Rf sandbox". All hell broke loose... I removed the link and put everything in a regular path. The theora problem #306 is still there, but maybe the above issues are gone. Build running... |
|
Build complete, without the symbolic link, results:
Conclusion: Your patches work. |
|
That's good to hear. Thanks. |

Hmm thought I had tesseract figured out, I'll look at it again...

Here's the "ffbuild/config.log" file. |

Build OK after this fix: eafb30d |

Clean build worked. Can be closed. |
Started a fresh build, it stops with "ERROR: tesseract not found using pkg-config"
Command was:
./cross_compile_ffmpeg.sh --high-bitdepth=y --gcc-cpu-count=4 --disable-nonfree=n --sandbox-ok=y --compiler-flavors=multi --build-ffmpeg-static=n --build-ffmpeg-shared=y
This has been tried twice, with and without the "--gcc-cpu-count=4" parameter. Same result.
A quick solution was to remove "--enable-libtesseract" around line 1667, but there must be reason why it won't find it although ./sandbox/cross_compilers/mingw-w64-i686/i686-w64-mingw32/lib/pkgconfig/tesseract.pc is there.
