compile fails on tesseract

[steveeaton]

In the c:\wbuild\openalpr\windows\tesseract-ocr\src directory there is a tesseract304.x64.support.diff file. It looks to me like the patch was bad or something.

I have tried x64, buildall, master, and v2.1.0 all the same

You are probably right about the patch being broken. It should work if you checkout master. I did a clean checkout a couple of days ago. I'd hold off with 3.04 since it requires openalpr training data to be retrained and there's also a bug in 3.04 causing less accurate OCR recognition results (2% worse on average).

[steveeaton]

I tried the following with the same result. I did not specifically target 3.04 or do anything with it, I am picking that up from one of the checkouts apparently. I just did it again to doublecheck

git clone https://github.com/openalpr/openalpr.git cd openalpr git clone https://github.com/peters/openalpr-windows.git windows git submodule update --init --recursive cd windows .\build.ps1 -Configuration Release -Platform x64 -PlatformToolset v120 -CudaGeneration None

[steveeaton]

By the way thanks for the amazing work. building openalpr was such a pain, I was getting ready to look at crosscompiling it. This really helps, and will help the project advance. Once I can get this to build, then I can start contributing, most likely in .NET, probably my first attempt will be to expose the character traits in .net

[steveeaton]

more info, I pulled down your 2.1.0 from a few days ago and got a similar error, but more detail

[peters]

Thank you for the detailed error report. Unfortunately I don't have time to look at this until next week since I have a deadline coming up shortly.

[peters]

@steveeaton I tried to reproduce the compile issue you are having. It compiled just fine for both v120 and v140. But what i did notice that you did not checkout branch v2.1.0.

Check that you are running a update to date git version, i'm running git version 1.9.5.github.0

Please create a new folder before you attempt these steps:

git clone https://github.com/openalpr/openalpr.git 
cd openalpr 
git clone https://github.com/peters/openalpr-windows.git windows 
git submodule update --init --recursive 
cd windows 

git checkout v2.1.0

.\build.ps1 -Configuration Release -Platform x64 -PlatformToolset v120 -CudaGeneration None

Elapsed: 00:09:13.1333212

[steveeaton]

I am not in any rush. The steps I posted above, are the steps from the openalpr-windows website.

I also did the exact same steps you posted above with the same results.

I will post some video later in the week.

[peters]

fatal: Not a git repository (or any of the parent directories): .git fatal: --index outside a repository

Git complains that about the tesseract directory not being a .git directory. This is why the patch is failing. So strange.

[peters]

What happens if you cd into tesseract-ocr\src and enter git status ?

[steveeaton]

on both versions it shows good

C:\xbuild\openalpr\windows [(v2.1.0)]> cd .\tesseract-ocr C:\xbuild\openalpr\windows\tesseract-ocr [(v2.1.0)]> git status HEAD detached at v2.1.0 nothing to commit, working directory clean C:\xbuild\openalpr\windows\tesseract-ocr [(v2.1.0)]>

[steveeaton]

I have other code I am working on this week, enjoy your week and I can work with you next week when you have time

[steveeaton]

ok back on it today. I am building on a 64bit MSI machine running windows 8.1.

You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example:

git checkout -b new_branch_name

HEAD is now at 3644b5b... Update patch to support compiling tesseract using visual studio 2015. This is based on the v3. 04 tag: https://github.com/tesseract-ocr/tesseract/commit/97080412fdc8cef05b1f917e698277cd01c6f004 C:\wbuild\openalpr\windows [(v2.1.0)]>

then I executed .\build.ps1 -Configuration Release -Platform x64 -PlatformToolset v120 -CudaGeneration None

leptonica and all of those up to tesseract build. Looking in the tesseract-ocr\src directory there is just the diff file there so it blows up at that point

[emrekenci]

@peters I'm having the same issue with @steveeaton.

I cloned this repo into the folder "openalpr-windows-2.1.0\tesseract-ocr\src".

Then ran the build command again.

The build went past this error.

But It failed again with this error:

     Creating directory "x64\LIB_Release\".

I'm investingating this.

[peters]

I'm sorry about the lack of feedback guys but I have a deadline until the end of the month.

@steveeaton

You must checkout v2.1.0 before you initialize the submodules.

@emrekenci

You cannot clone the tesseract repository directly you have to ensure that current HEAD points to SHA #449fc8a

[steveeaton]

help please, thanks!

[abusby]

Just in case someone else comes across this and is having the same problem, which i also ran into this is the correct sequence of commands to get build to work.

git clone https://github.com/openalpr/openalpr.git cd openalpr git clone https://github.com/peters/openalpr-windows.git windows cd windows git checkout v2.1.0 git submodule update --init --recursive

This will download all of the correct files. The just run your desired build command

[schallot]

@abusby's comment helped me get closer, but now I get the following errors:

Anyone else see this?

[sompjang]

I have same problem as @schallot. Did anyone resolve that?

[sompjang]

I solve this priblem by commenting these functions in openalprgo.cpp... but after that I have got another problem.

When I try to compile configuration for debug I get these errors:

openalpr-static.lib(alpr_impl.obj) : error LNK2019: unresolved external symbol "public: thiscall alpr::StateDetector::StateDetector(class std::basic_string<char,struct std::char_traits,class std::allocator >,class std::basic_string<char,struct std::char_traits,class td::allocator >,class std::basic_string<char,struct std::char_traits,class std::allocator >)" (??0StateDetector@alpr@@QAE@V?$basic_string@DU?char_traits@D@std@@V?$allocator@D@2@@std@@00@Z) referenced in function "public: thiscall alpr::AlprImpl::AlprImpl(class std::basic_string<char,struct std::char_traits,class std::allocator >,class std::basic_string<char,struct std::char_traits,class std::allocator >,class std::basic_string<char,struct std::char_traits,class std::allocator >)" (??0AlprImpl@alpr@@QAE@V?$basic_string@DU?char_traits@D@std@@V?$allocator@D@2@@std@@00@Z) [E:\skola\openalpr\windows\build\artifacts\2.2.0\v140\Debug\win32\openalpr\misc_utilities\openalpr-utils-binarizefontsheet.vcxproj]

Can anyone help?

[tek-noid]

For this to compile, I used the proper build instructions here For the "redefinition" errors, I made these changes in openalpr\src\bindings\go\openalprgo.h

#ifdef __cplusplus
extern "C" {
#endif

#if !defined(OPENALPR_EXPORT)
#define OPENALPR_EXPORT
#endif

    typedef void* Alpr;

    OPENALPR_EXPORT Alpr AlprInit(char* country, char* configFile, char* runtimeDir);
    OPENALPR_EXPORT void SetDetectRegion(Alpr alpr, int detectRegion);
    OPENALPR_EXPORT void SetTopN(Alpr alpr, int topN);
    OPENALPR_EXPORT void SetDefaultRegion(Alpr alpr, char* region);
    OPENALPR_EXPORT int IsLoaded(Alpr alpr);
    OPENALPR_EXPORT void Unload(Alpr alpr);
    OPENALPR_EXPORT char* RecognizeByFilePath(Alpr alpr, char* filePath);
    OPENALPR_EXPORT char* RecognizeByBlob(Alpr alpr, char* imageBytes, int len);
    OPENALPR_EXPORT char* GetVersion();
#ifdef __cplusplus
}
#endif

and in openalpr\src\bindings\go\openalprgo.cpp I moved the include of the above header after the definition of OPENALPLR_EXPORT, ala

#include <alpr.h>
// Remove header from here
extern "C" {

#if defined(_MSC_VER)
    //  Microsoft
#define OPENALPR_EXPORT __declspec(dllexport)
#else
    //  do nothing
#define OPENALPR_EXPORT
#endif

#include "openalprgo.h"

And Finally, to address the wrong Libraries being referenced during the LInk phase, in Build.ps1, I made this change in the Copy-Sources function

        Vcxproj-Set $VcxProjectFilename '/rs:Project/rs:PropertyGroup[@Label="Globals"]/rs:OpenALPRVersion' $OpenALPRVersion
        Vcxproj-Set $VcxProjectFilename '/rs:Project/rs:PropertyGroup[@Label="Globals"]/rs:TesseractVersion' $TesseractVersion`

After this, I was able to successfully process one image. The next image throws an error, so I need to figure that out.

Caught exception in OpenALPR recognize: C:\inhouse\openalpr\windows\opencv\modules\core\src\ocl.cpp:5118: error: (-215)
clEnqueueWriteBuffer(q, (cl_mem)u->handle, CL_TRUE, dstrawofs, total, alignedPtr.getAlignedPtr(), 0, 0, 0) >= 0 in function cv::ocl::OpenCLAllocator::upload

[shamsuddinladha]

I did what @tek-noid suggested. In addition

• I commented the include "openalprgo.h" directive and
• Added typedef void* Alpr; directly in the .cpp file and that solved the problem. I could compile and run the code.

I noticed the if you checkout the v2.2.0 tag of https://github.com/openalpr/openalpr then the build succeeds. So the above compiler error was caused by a commit subsequent to the v2.2.0 release of OpenALPR.

To checkout v2.2.0, do this in your openalpr directory (not in the windows subdirectory)

git checkout tags/v2.2.0 -b v2.2.0
