I'm trying to step into tesseract library function and I get "No implementations found" error message. Fair enough - I haven't shown Lion where the source code is located because I can't find such an option.
I have found the answer - some goo soul has created a CMake Tesseract OCR project at https://github.com/aspotashev/tesseract-ocr-cmake

I'm trying to use ROS for Windows for the first time, with a package that was previously developed in Linux.
Doing the catkin_make I find this error:
LINK : fatal error LNK1104: cannot
open file 'rt.lib'
I think the problem is in my CMakeLists.txt where I have:
target_link_libraries(omni_state HD HDU rt ncurses ${catkin_LIBRARIES})
I had a similar problem with HD.lib and HDU.lib, bacause I guess that the automatic find_path doesn't work well (or at all :P) in Windows. So I added
link_directories(path_to_lib_dir)
solving the problem. I would like to do the same thing for rt, but I can't find rt.lib in my PC. I also searched how to download it but I can't find a way.
Can someone help me?
I followed this tutorial for the installation process: https://www.youtube.com/watch?v=o62iO8SssZk
So I've done all the steps and it works except when I try to execute main.cpp, build fails and it throws the error: library not found for -lHalf-2_4.24.0.0
So I tried to find this library and add it to the project but I couldn't even find such a library in the folder and don't know how to solve this problem. Any help would be greatly appreciated.
In order to open the examples provided from the textbook, I downloaded the examples from the book's website at opengl-book.com.
The instructions say:
Point CMake to the folder and VS 2013 is suppose to take it from there.
However, I get and error message on CMake.
Error says:
'Error in configuration process, files may be invalid'.
CMake Error: The source directory "E:/OpenGL ES/opengles3-book" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.
What step am I missing here?
Well, the error message is pretty clear. You are missing a CMakeLists.txt in the said folder. I don't know what instructions you are following, but I suggest you take a look at how CMake works, e.g. http://mirkokiefer.com/blog/2013/03/cmake-by-example/.
I am trying to compile a C++ project that uses OpenCV and Tesseract(not iOS) in Xcode 5.1. I have downloaded OpenCV and Tesseract and the header and library files are sitting in my /usr/local/include/ and /usr/local/lib/ folders respectively.
I have tried modifying my Xcode project "Header search paths" and "Library search paths" to include the above two folders according to this.
However, I am getting the following compilation errors in round robin fashion
"Lexical Preprocessor Issue - 'tesseract\baseapi.h' file not found"
"Lexical Preprocessor Issue - 'opencv\cv.h' file not found"
I have also tried adding specific paths for tesseract and opencv with no luck.
Has anyone fixed this issue before?
The issue was fixed when the libraries were added to the Xcode project. Refer to https://gist.github.com/balazspete/6982565
I'm trying to compile the qtdensity example from the RInside examples folder, using Qt, Windows 7, R 32bit.
I have followed all the instructions posted online on how to set up these tools since my ultimate goal is to develop a C++/R application in Qt.
When I try to build the project I get the following error:
E:\dev\R-2.15.2\library\RInside\lib\i386\libRInside.a:-1: error: file not recognized: File truncated
Indeed, the libRInside.a file is empty as well as the libRInside.dll file in the same folder.
I have installed, uninstalled, installed again the RInside package using the install.packages("RInside", type="source") command.
The same problem does not occur with the Rcpp package, installed the same way.
I would greatly appreciate any insights on this. I've recently started with C++ and as a result it has taken me a lot of effort to set up everything so far.
Thank you!
Laura
Not sure what I did wrong but I solved it by copy-paste the same files from the archive available at the CRAN page of RInside
