I've been working to get tesseract 4.0 compiled using emscripten so I can use it in a javascript project. It has a dependency of leptonica, which has a ton of dependencies as well. All told there are 8 libraries in total. One by one I worked through getting them to compile using emcmake or emmake, often I had to modify their CMakeLists.txt file to get them to allow me to pass the location of the libraries on the command line during the build process. I have them all compiled now as static libraries. I'm now trying to turn them into one big javascript file. I'm using this command:
emcc libz.a libgif.a libjpeg.a liblzma.a libpng.a libtiff.a libleptonica.a liblibtesseract.a -o javascript/libtesseract-asm.js -s EXPORTED_FUNCTIONS="['TessBaseAPICreate', 'TessBaseAPIInit3', 'TessBaseAPISetImage2', 'TessBaseAPIRecognize', 'TessBaseAPIGetUTF8Text', 'TessDeleteText','TessBaseAPIEnd','TessBaseAPIDelete','pixDestroy', 'pixRead','pixReadMem']" Two of those exported functions are from Leptonica (the last two) and the rest are from Tesseract. When I run that command without the export functions it works makes a 3.5MB javascript file with a ton of mangled looking names. When I try to use the export functions it says they don't exist. I have tried to follow the directions on the site as best I can, but I don't understand where to go from here. If someone could point me in the right direction I would appreciate it. --Robert -- You received this message because you are subscribed to the Google Groups "emscripten-discuss" group.
