Tesseract: Use VS2015 to build the tesseract-ocr master banch，it‘s not work

[Jesson029]

I use Cppan + VS2015 to build the tesseract-ocr master banch，it‘s not work.
It always give me LKN2001 and LNK2019 Error when I compling libs of cppan on VS2015

[zdenop]

This is really wrong issue report. Information "It always give me LKN2001 and LNK2019 Error when I compiling libs of cppan on VS2015" is useless.
Please provide list of all steps what you did including logs for each step.

BTW: Yesterday I build master with VS2017 and cppan without problem.

[Jesson029]

Use MS-PS to Run:
cd tesseract
.\cppan
mkdir VS2015-x86
cd VS2015-x86
cmake ..

[Jesson029]

cppan cmd present:

I think it's OK.

OK too!

then Use VS2015 to build，it present:

Error Messages of my chinese customer email to me

[egorpugin]

VS2015 may not work anymore (not 100% sure) - please try VS2017.

[zdenop]

@egorpugin: do you know last version working with VS2015?

[egorpugin]

Tess 3.05 worked I think.
But as for today - some cppan packages are changed (not that much but still). And I don't have vs2015, so it's just untested.

[barry15321]

Actually , I encountered the same problem ( 4.0 & 3.05 )
after fixing encoding format problems , it showed LNK 2019 errors
and also another errors showed that missing '.cppan\storage\lib\c98ba788\Debug\pvt.cppan.demo.unicode.icu.i18n-61.1.0.lib' files

I checked .cppan\storage , In .cppan\storage\src\0b\29\775e\i18n folder that contain its .cpp & .h files
but It doesn't generate lib files that I need.

I want to include Tesseract into my C++ project
so I need dll , lib and those h , cpp files for project , right?
sorry in advanced , pretty new to this

[Jesson029]

I think cppan-libs of newly added has some problems when work with VS2015

[Shreeshrii]

pvt.cppan.demo.unicode.icu.i18n-61.1.0...

Is that the correct icu lib version to be used for tesseract?

[barry15321]

cppan just download those packs automatically like this
is there something wrong? sry , Im not quiet sure.

btw , gfileutils.c file can't be save as (GB2312-80) format in advanced save options
and this is why it shows a lot of errors when compiling , I think

[Jesson029]

Format of UTF-8 With Signed has the same error still !!!

[Jesson029]

Can you compile the master bench with VS2015???

How to do? Can give me some guidances?

[zdenop]

@barry15321 : goption.c is UTF-8 encoded. Why are you changing encoding?
@Jesson029 : what do you mean with "Format of UTF-8 With Signed has the same error"? Can you provide details?

[Shreeshrii]

@egorpugin Is it possible to change appyeyor build to use VS2015 as a test and see where the errors occur?

[amitdo]

f58522ac624e (VS2015 -> VS2017)

[Jesson029]

@amitdo @Shreeshrii

at 2017，4.0.0 alpha bench can be compiled with cppan + VS2015. It's worked.
but 4.0.0 beta and master cannot.

appyeyor.yml of 2 version is almostly same.

I do not think this cause problems.

[egorpugin]

Is it possible to change appyeyor build to use VS2015 as a test and see where the errors occur?

It's possible. I've added vs2015. Let's see how it goes.

[egorpugin]

Bad thing is that I cannot control appveyor jobs - start,stop,restart. For example, current job seems to be stuck. But I have to wait for other ~50 mins for appveoyr to kill it.

[egorpugin]

Ok, error was on cppan side. Sorry for that.
I've fixed it, please, try again.

[egorpugin]

Ok, VS2015 builds fine now.
https://ci.appveyor.com/project/zdenop/tesseract/build/master.1645

[Jesson029]

I try it now, I will feedback the results。

@egorpugin thank you.

[Jesson029]

@egorpugin thanks.

Now it can be compiled successly.

[barry15321]

@egorpugin
@Jesson029
thank u guys , so so much

[hsqaihkl]

@Jesson029 Hi ，could you provide you code in VS2015/2017 code for me？

[nxsf8023]

Local db data caused issues, trying remote one
Requesting dependency list...
Reading package specs...

when I use cppan, always this error.

[egorpugin]

It's not an error.

[yjm919]

try other version cppan,the same question ,i use an older version,!!!!!!!!!!! then is ok

[JHChen1993]

@egorpugin thanks.

Now it can be compiled successly.

could you provide you code in VS2015/2017 code for me？

[wanlipeng]

Local db
I also face this problem, would you have a solution with it，thanks for your reply.

[egorpugin]

It is better to use sw today instead of cppan.
