Rtesseract requires Tesseract to be installed, either 3.0X or 4.0X versions. For general notes on installing Tesseract, please see Compiling Tesseract for information from the Tesseract devs and Installing Tesseract for our notes.
These are platforms where Rtesseract has been confirmed to install on, along with any notes or special instructions.
-
Requires the environment variable PKG_CONFIG_PATH set to include the appropriate location so the installer knows where to find tesseract and leptonica, e.g., /usr/local/lib/pkgconfig. This is a colon-separated collection of paths identifying directories that contain the .pc files specifying the information for an installed package.
-
Compilation should use the C++11 standard. This means setting the --std=C++11 flag in CXXFLAGS. Otherwise, the compiler will issue warnings.
