That's because libtesseract.so is linked to a different C++ standard library.

How to check packages using the clang compiler without compiling the rest of the system from source using clang? How do other C++ packages solve this problem? -- Best regards, Ivan ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
