Hello.
I'm *desperately* trying to compile Tesseract-ocr (4.0) on a Windows Machine with some restrictions. - We are doing multi-platforms : an automated compilation must be possible (command-line) - We are using specific 3rd party libraries : the compilation must accept custom path / libraries for most of its dependencies - We are already using most of the 3rd party libraries for other part of the code : the compilation must not recompile them (thus, no cppan) - Leptonica has been built with our special 3rdparty (ZLib, LibPng ..) - Our project must "include" tesseract alongside theses specific 3rdparty Problem : I have strong issue specifying custom paths for Tesseract. Under Unix (CentOS, Ubuntu 16/18, Debian 8/9 ..), I was able to achieve my goal with the tools *autogen* *autoconf* *autoheaders* *pkg-config*. Under Windows, autoconf-archive and pkg-config are unavailable (from what I know) ; making autoconf unusable. I was neither able to compile using CMake and specifying a custom path for Leptonica. Under Linux : 1. Merging libraries ZLib/LibPng/LibTiff/LibJpeg with Leptonica (ar) 2. Creating a modified pkg-config with the path to this modified liblept.a 3. autogen.sh 4. LIBLEPT_HEADERSDIR=`pwd`/Leptonica/include ./configure --prefix=`pwd`/install --with-extra-libraries=PATH/TO/LEPTONICA PKG_CONFIG_PATH=PATH/TO/PKG LDFLAGS="-LPATH/TO/LEPTONICA" CPPFLAGS="-IPATH/TO/ZLIB -IPATH/TO/LIBPNG ..." 5. make Under Windows : 1. Trying with pkg-config : installation of pkg-config with mingw failed 2. Trying with cppan + cmake visual studio : could not figure how to separate cppan from tesseract in the project 3. Trying with cmake, CMAKE_PREFIX_PATH, CMAKE_MODULE_PATH, Leptonica_DIR : missing config files from Leptonica (LeptonicaConfig.cmake or leptonica-config.cmake) 4. Trying under Linux Ubuntu 16 with gcc-mingw-w64 : failed to link against tesseract and leptonica libraries under Windows (new Visual project) I can detail any of theses steps if you need further information. Is there any way to simply specify the path to Leptonica include/lib with cmake ? Is there any restriction for the compilation to look only for an include folder and a library ? Did you planned users to compile with non-default libraries ? Thank you in advance. Arnaud LOYER. -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
