My apologies, it's supposed to be "make training" not "make install"!

1. Training is not supported on windows.
2. If you want to test/fix something, use the current code from repository (it 
should be posible to build it with msys2[1] on windows)

Tesseract team should REALLY address in the project page and README file that 
TRAINING IS NOT SUPPORTED ON WINDOWS! What a waste of time trying to compile 
the training tool on Windows!

Is there any plan to support training on Windows?

3.03 was not really released (there was on release candidate for testing).
New version of tesseract needs leptonica 1.71 but there in no official release 
of it (at least for MS Visual studio). 
Training tools need a several additional libraries (with their own 
dependencies) that are common on linux but not on windows.
So if you need Windows support it is up to you if you invest (or waste) you 
time for it. Patches (or compiled libraries) are welcomed.

I have turned to use Xubuntu 15.04 to compile the training tools. I 
successfully compiled the main program tesseract with `make`. But when trying 
to `make training`, I encountered the following error:

libtool: link: 'boxchar.lo' is not a valid libtool object.

Actually, I have seen such error on MSYS2, too.

Could anyone shed some light?

I do not use Ubuntu, but according this blog http://tomsik.eu/train_tesseract 
it should be easy.

Maybe first check if they did not included training tools to distribution.
If you anyway insist to build them from source and you still get error during 
building training tools try first this:
    cd training
    make clean
    make

Thanks for your reply.

I downloaded the 3.03 rc1 source from the official Google Drive: 
https://drive.google.com/folderview?id=0B7l10Bj_LprhQnpSRkpGMGV2eE0&usp=sharing

After I configure the package, it says I can build the training tools with 
"make training". 

I remember I read somewhere that there's no pre-built 3.03 package. So I have 
to compile it from source. To be specific, I need the "text2image" tool to ease 
the tiff/box files generation. Only 3.03 contains it.

I will try your suggestion and reply soon. Thanks.

I followed the blog you mentioned: http://tomsik.eu/train_tesseract.
And both main program and training tools are successfully built now.

Note that the downloaded source is 3.03.03, not 3.03 rc1. I am not sure if 
3.03.03 is officially released. And I want to know what the latest version is.

Since I need to use the tesseract.exe and releated dll on Windows. And the 
text2image is only available on linux. I think I will have to split the 
training process on 2 platforms.

I will try it and update later.

Have a look at tesseract and tesseract-dev forums for explanation about version 
3.03 in Ubuntu (and debian?). Ubuntu 3.03.03 should be 3.03rc1 with some 
additional patches...

Hi zde..., could you take a look at the threads below? It's kind of urgent. And 
I think you have the authority to answer it. Thanks.
