Using Tesseract in MFC

I am struggle to use tesseract library into MFC VS2010 project. And I guess I started like this: I have tried to compile tesseract library from here: https://github.com/tesseract-ocr/tesseract ... but when I tried to create a solution with CMake, I get the following error from CMake:

Code:

---

CMake Error at CMakeLists.txt:100 (find_package):
  Could not find a package configuration file provided by "Leptonica"
  (requested version 1.74) with any of the following names:

    LeptonicaConfig.cmake
    leptonica-config.cmake

  Add the installation prefix of "Leptonica" to CMAKE_PREFIX_PATH or set
  "Leptonica_DIR" to a directory containing one of the above files.  If
  "Leptonica" provides a separate development package or SDK, be sure it has
  been installed.

Obviously, I need leptonica ...but whre can I get this library ? I read that is used in tesseract projects ...

Or else, have you already compiled tesseract with VS2010 ? Can you lead me into solving my task ? Thank you.

Did you try to google for this problem?

This problem I didn't searched on internet, I admit that :D .. thank you for idea. However, I didn't found something about leptonica library on github ....

If I compile tesseact library in VS2017, could I use this compiled lib and dll into VS2010 project ?

Because I have compiled Leptonica, but when I compile tesseract, I get a bunch of errors ... and I guess is because VS2010 compiler is the point:

Code:

---

3>c:\flaviu\tesseract-master\src\arch\dotproductavx.cpp(30): error C4716: 'tesseract::DotProductAVX' : must return a value
3>
3>Build FAILED.

3>Time Elapsed 00:00:00.36
2>C:\Flaviu\tesseract-master\src\ccutil\host.h(30): fatal error C1083: Cannot open include file: 'cinttypes': No such file or directory

---

the code:

Code:

---

namespace tesseract {
double DotProductAVX(const double* u, const double* v, int n) {
  fprintf(stderr, "DotProductAVX can't be used on Android\n");
  abort();
}
}  // namespace tesseract

---

and

Code:

---

#include <cinttypes>  // PRId32, ...

---

<cinttypes> was introduced with c++11 - so you need at least a c++11 compatible compiler. VS2010 is not c++11 compatible so you'll need a later version of the compiler to compile this code.

So, if I would compile this library with VS2017 let say, I could use this library inside of VS2010 project ?

probably, yes.
Just try it!

Note that each version of VS c++ uses it's own version of the crt - so the.dll compiled with VS2017 will use a different version of the crt to code compiled with VS2010. This may, or may not, be an issue - but for any computer on which you want to run these programs you'll need to have at least these different versions of the crt installed.

Why ask? Just try it.

From my experience, I knew that is impossible to go everything alright :D

I have installed VS2017 on my machine ... but when I have tried to create a simple MFC test project, I have met the following error:Attachment 35343
Ok, so I have tried to create a solution file for tesseract, with CMake, and here is the result:

Code:

---

CMake Error at CMakeLists.txt:41 (project):
  Generator

  could not find any instance of Visual Studio.

I run on the empty road ...

Are you banned by Google?

No, of course not, and I have searched a solution for my problem, but I didn't found something relevant ... might haven't used right terms ...

When you installed Vs2017, did you tell the installation configuration that you wanted c++/mfc/SDK etc etc for desktop? I don't think they are installed by default now.

Run the VS installer, click modify and under Installation Details, what have you installed for Desktop Development with C++?

Yes, I have checked these details, and I noticed that I haven't installed all components for my needs ... and I have installed them, and I have successfully compiled leptonica and tesseract library ... now it come to used them, inside of VS2010 project ... I am very curios if will work ...I will come back with feedback.
