Build error: C2109

[steve-morries]

Version: both current (Mar 2, 2014) and tesseract-vs2012-1.70

When executing "msbuild.exe build.proj" using Visual Studio 2013, I encounter the following errors:

src\pngread.c(109): error C2065: 'png_libpng_ver' : undeclared identifier [tesseract-vs2012-1.70\libpng\libpng.vcxproj]
src\pngread.c(109): error C2109: subscript requires array or pointer type [tesseract-vs2012-1.70\libpng\libpng.vcxproj]
src\pngread.c(111): error C2065: 'png_libpng_ver' : undeclared identifier [tesseract-vs2012-1.70\libpng\libpng.vcxproj]
src\pngread.c(111): error C2109: subscript requires array or pointer type [tesseract-vs2012-1.70\libpng\libpng.vcxproj]
...

It seems that version information is missing.

I just built the current version and it worked fine here unfortunately. When you say you executed "msbuild.exe build.proj" using Visual Studio 2013 do you mean the VS command prompt (e.g. "Developer Command Prompt for VS2013")? Also might be worth directly opening the sln in VS 2013 and seeing if you get the same errors.

Charles, thanks for getting back to me. Yes, I am using the "Developer
Command Prompt for VS2013". I cloned the repository and run "msbuild
build.proj" and got the same error. Is there any environment variable need
to be set?

I just built the current version and it worked fine here unfortunately.
When you say you executed "msbuild.exe build.proj" using Visual Studio 2013
do you mean the VS command prompt (e.g. "Developer Command Prompt for
VS2013")? Also might be worth directly opening the sln in VS 2013 and
seeing if you get the same errors.

Ok, i'll have another look tomorrow maybe I missed something. By the way
png_libpng_ver is defined in png.h - line 447 so should be ok. From memory
I did have some trouble getting libpng to compile since it uses a
precompiled header maybe thats got something to do with it.

Charles, thanks for getting back to me. Yes, I am using the "Developer
Command Prompt for VS2013". I cloned the repository and run "msbuild
build.proj" and got the same error. Is there any environment variable need
to be set?

I just built the current version and it worked fine here unfortunately.
When you say you executed "msbuild.exe build.proj" using Visual Studio
2013
do you mean the VS command prompt (e.g. "Developer Command Prompt for
VS2013")? Also might be worth directly opening the sln in VS 2013 and
seeing if you get the same errors.

OK, I've just run through an another build this time after resetting the directory (git clean -d) and it still built fine. On closer inspection of your build log I did notice the line, which may indicate an error though not sure:

    Creating "C:\tesseract-vs2012\build\obj\Win32\Debug\libpng-143\libpng-143.tlog\unsuccessfulbuild" because "AlwaysCreate" was specified.

Also I'm assuming that building the solution in VS 2013 produces the same errors.

Otherwise I'm completely stumped, Sorry.

I am getting even more errors. :(

libpng is always involved.

I just wanted to let you know. I will let you know when I know more.

The latest Tesseract 3.04 source can no longer be compiled with VS2013 due to recent updates and Leptonica 1.71 upgrade. Can you please update the VS2013 project?

[charlesw]

I'll see what I can do, can't give any time lines though.

Thanks Charles and Paul. The patch worked good. Compiled Tesseract 3.04 beta is running well.
