error LNK2019: unresolved external symbol on all function call defined in 'allheaders.h'

What steps will reproduce the problem?
1. Download and use the static libraries and include file
2. VS 2012 on Windows 8 Pro 64-Bit
3.

What is the expected output? What do you see instead?
I expect the application to compile but am getting LNK2019 errors on all 
functions defined in allheaders.h

What version of the product are you using? On what operating system?
Windows 8 Pro; Visual studios 2012; Leptonica 

Please provide any additional information below.

What steps did you follow to make your VS2012 application? Have you read 
"Building and Linking with liblept using Microsoft Visual Studio 2008" at 
http://tpgit.github.io/UnOfficialLeptDocs/vs2008/index.html ? Even though 
that's specifically for VS2008 much of the same info should still (I hope) 
apply to VS2012.

I have followed the steps as indicated and if I use the pre-built static 
libraries I get the errors described above. When I try to build from the source 
code provided I get the following errors:

Wow. I have no idea what you are doing :)

Maybe the best way forward is for you to first try Visual Studio 2008, since 
that is a known working solution. You can still get Visual C++ 2008 Express 
free at:

Any ideas what can be causing this? Any help will be appreciated! FYI. I am 
using the leptonica-1.69 sources.

Thanks in advance,

AK

Original comment by adn...@gmail.com on 15 Jul 2013 at 2:08

Just a quick update. I used the leptonica-1.68 instead of the leptonica-1.69 
sources and everything seems to compile just fine in VS2008. What would you 
recommend I do in order to get it up and running to be used by an application 
developed in VS2012 on Win8Pro?

Thanks,

AK

Original comment by adn...@gmail.com on 15 Jul 2013 at 2:21

OK. So I now have the Leptonica stuff working on a VS2008, win32 setup. I am 
able to manipulate, rotate by shear small tiff images. My issue now is the 
rotate by shear of larger tiff files (5080dpi X 20in x 20in) which is what I 
need to do. I keep getting pix_malloc fail for data and pixd not made errors. 
Is there anything that can be done for this?

Thanks,

AK

Original comment by adn...@gmail.com on 15 Jul 2013 at 6:07

malloc is failing in pixCreateNoInit() because you're asking for an array that 
is too large.  You're asking for an array that is 100K pixels on a side, which 
is 1 trillion pixels!  The biggest image data array allowed in leptonica is 2 GB

Original comment by dbloomb...@google.com on 15 Jul 2013 at 8:30

no, my mistake, it is 10 billion pixels.  You can make a 1 or 2 bpp image that 
large, but nothing with more depth.

Original comment by dbloomb...@google.com on 15 Jul 2013 at 8:34

A 20in x 20in x 5080dpi 1-bit tiff image will require a buffer of size of about 
1.44GB so it should work, but it is not. Is there any way to increase the max 
buffer allowed in Leptonica?

The issue with the Chinese/Japanese character file names not found was resolved 
by manually fixing the leptonica.vcxproj file for VS2012 and it is now 
compiling for both DLL Release and DLL Debug, win32. I can provide details if 
required.

Original comment by adn...@gmail.com on 16 Jul 2013 at 2:40

I agree that a 1 bit tiff of that size should not cause a malloc failure.  Just 
for sanity, please check the values of the args to pixCreateHeader(), which is 
called just before the malloc.

Original comment by dan.bloo...@gmail.com on 17 Jul 2013 at 4:31

The values for the width and height and depth are: 101600, 101600, 1 
respectively. This amounts to 1.201GB memory required. pix_malloc is returning 
NULL with input values of 4 * 3175 (wpl) * 101600 (height). Any ideas why this 
might be happening?

Original comment by adn...@gmail.com on 17 Jul 2013 at 5:57

malloc succeeds on linux (gnu runtime) with these parameters.  I don't know why 
it fails on windows.

Original comment by dbloomb...@google.com on 17 Jul 2013 at 11:52

Hi. Thanks for your input. I am not sure why this is happening either. What I 
am doing now is building all the various projects (zlib128, libpng, libjpeg, 
libtiff and giflib) from source. I am doing so on a windows 8 x64 system using 
VS2012 and tools. I have managed to compile and test zlib128, libpng and 
libjpeg following the instructions provided on Leptonica. The issue now is that 
when I try to nmake libtiff, I get the following link errors:

Any ideas why this might be happening? Thanks.

Did some digging into this issue and it seems that the libtiff does not like 
the x64 compilation of the jpeg and zlib. Are there any instructions or 
suggestions on how to compile the libtiff in x64? Thanks.

Original comment by adn...@gmail.com on 23 Jul 2013 at 4:56

OK. I got everything working in windows 8 pro x64 in VS2012! I had to run 
vcvars64.bat for the nmake for libtiff. I am now able to call liblept functions 
from my application. Thank you all for your time and help. If anyone needs any 
info regarding what I did. I will be more than happy to help out. Thanks.

great -- glad you got it working, and I'm sorry it was so much trouble.

TomP may ask you for a short writeup of the extra steps you found necessary to 
get this running under VS2012.

And thanks for your help debugging Windows  :-)

Changed state: Fixed

It was a good learning experience. I will be more than happy to provide TomP 
any information required. Please let me know what you need.

1 thing I forgot to mention is that now on this system (win8Prox64-VS2012x64) I 
am not getting the malloc issue from before. I am able to process (rotation by 
shear) 20in x 24in x 5080dpi TIFF images without any issues.

I am not sure if this is the correct place to post this but here goes:

The final goal for me is to use a GPU (Nvidia K10) to speed up the Leptonica 
image processing using the CUDA platform. I am particularly interested in doing 
this for the rotation by shear on a large format TIFF files. I think porting 
the code for shearing to CUDA would be one way.

Has any thought or work been done on this? Any ideas or suggestions will be 
appreciated.

Thanks.

This has been brought up on several occasions.  I have no plans to pursue it.  
A straight-forward application might be to pixConvolve() or fpixConvolve(), 
which are relatively slow on leptonica and, as FIR filters, should be easily 
parallelized.  My guess is that pixRotate() would be tricky.  There exist C --> 
CUDA translators, and it would be interesting to find out what kind of speedup 
is easily obtainable using a translator for these functions and some NVIDIA 
hardware.

Original comment by dan.bloo...@gmail.com on 24 Jul 2013 at 8:49

I agree with your analysis and do have access to such a translator. I will 
pursue this and let you know of any updates and/or progress. I hope it is OK if 
I ask questions here regarding the current Leptonica source code. Thanks again.

Ooops. Sorry for not responding earlier. I flagged this issue for email 
notification but then never noticed that gmail was sending all of them to my 
spam folder :(. I just assumed that something from google codesite would never 
be spam. Live and learn. I just happened to wonder today what ever happened 
with this issue and manually looked for it again.

Anyway, glad you got everything sorted out. Some comments:

Your initial root problem was because you were trying to use leptonica v1.69 
with the v1.68 solution. In hindsight, I'm not surprised that you got all those 
unresolved symbols since you were attempting to link to the wrong library. 
v1.69 has never been "officially" supported on Windows as it is a linux-only 
release.

Memory issues. The provided VS2008 Solution is for creating *32-bit* binaries. 
Even if you are running on Windows 64-bit you still can only access a 32-bit 
address space. And while I forget the exact details, I believe even then you 
only are able to get 1/2 of 3GB (Windows takes up 1GB and then uses half the 
address space for system memory --- or something like that). In any case you 
empirically determined this yourself.

So the solution, as you eventually discovered, is that you have to rebuild 
*everything* as 64-bit binaries, including all the prerequisite image 
libraries. I've always knew this was possible (and probably not too difficult), 
but have never tried to do it myself. Thanks for confirming this belief :)

I've heard over on the tesseract mailing list unconfirmed reports (at least by 
me) that the free Express versions of Visual Studio don't come with 64-bit 
compilers. This might be a problem for some people, and is one argument for 
providing both 32-bit and 64-bit prebuilt binaries (ugh!).

VS2012. I haven't done this myself, but I assumed that it would be relatively 
simple to use the VS2008 Solution with VS2012. Certainly moving from VS2008 to 
VS2010 isn't that hard.

libtiff. The v1.68 documentation discusses bulding and using libtiff 3.9.4. 
There is also libtiff v4.x which supports "bigtiff" [1], that is images that 
are bigger than (4GB or even only 2GB depending on the implementation). You may 
run into this limit also.

As far as using CUDA is concerned I wouldn't initially bother with Leptonica. 
Instead see the CUDA Imaging Samples [2], StackOverflow [3], or even the PyCUDA 
example [4]. Googling gives all sorts of hits for "cuda example rotating image".

Thank you very much for the detailed response. No worries. It happens :)

Over all the Leptonica library is great for image processing. Its a job well 
done, so thank you for that.

Our requirements is, as you may have guessed, large format TIFF image rotation 
in real time. The rotation by shear is what we are after and that is what I am 
trying to implement in CUDA. Also Leptonica allows for easy TIFF image data 
handling.

I have looked at the links you gave, which CUDA Imaging Sample[2] in particular 
do you think will be a good place to start? The StackOverFlow [3] I am familiar 
with but we feel that using trig functions will greatly effect the speed of the 
rotation hence the shear method.

TIFF handling has to be done by us and CUDA does not seem to offer such support 
unless I am wrong.

Any further advise would be greatly appreciated.

Original comment by adn...@gmail.com on 14 Aug 2013 at 2:45

Re-reading my comment I see I came across as more authoritative than I 
intended. I mentioned the CUDA samples mainly in reference to Dan's comments 
about pixConvolve since there appear to be many examples of doing that using 
CUDA.

As far as the stackoverflow link, I suggest just trying it first and seeing how 
fast the "slow"/easy method is. Maybe it will be fast enough?

Presumably, thoroughly reading and understanding nVidia's Performance 
Guidelines [1] will help? In particular, "5.4. Maximize Instruction Throughput" 
[2] and "D.2. Intrinsic Functions" [3] talk about your valid concerns with trig 
functions.

Also I might mention that the various rotation methods can introduce more or 
less artifacts. In some cases it is better to be accurate rather than fast. But 
I guess since you have already decided on rotation by shear that this does not 
apply in your case?

Finally, have you looked into using nVidia's Performance Primitives [4]? It 
already has a rotate and lots of other image processing operations. Since I 
gather that rotation by shear is implemented via rasterops, maybe it would be a 
simple translation to use NPP's functions instead?

Thank you again for your input. I have gone through the various documentations 
and done the calculations regarding the trig functions and they do add 
substantial delays for our application.

Artifacts are definitely an issue and I agree that accuracy is preferred to 
speed. The rotation by shear in Leptonica gives very good and usable results. I 
have checked and tested the output rotated files.

I have given the NPP rotation functions a try but there is a limitation on the 
size of the TIFF files. It will not accept the file sizes we need to use.

I am quite convinced that implementing your rotation by shear method in CUDA is 
probably the right way to go, unless proven wrong :)

The issue there for me right now is figuring out exactly what parts to port to 
CUDA in order to get it at least working; optimization can come later.

Thanks to comments in issue #93, I've been informed that the original problem 
is due to the bug mentioned at [1]. Apparently converting from a VS2008 
solution to VS2012 causes it if certain elements in the .vcxproj xml file 
contain a newline in them. In this case you need to remove the newline from all 
<Command> elements.
