## Problem using libtiff in debug mode with visual studio 2010

 Hello, I am using libtiff with visual studio 2010. When I use it in the "Release" mode of visual studio, everything is working fine. But when I switch visual studio to "Debug" mode, I have the following popup error that comes when I call TIFFOpen: it's written: Debug assertion failed! Program: C:\ProjetsEnCours\LastTryWithOpenCvInside\Debug\LastTry.exe File: f:\dd\vctools\crt_bld\self_x86\crt\src\fstat64.c Line 94 Expression: (_osfile(fildes) & FOPEN) For information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts. Has anyone already had the same error and know how the resolve it? Thanks, Emmanuel _______________________________________________ Tiff mailing list: [hidden email] http://lists.maptools.org/mailman/listinfo/tiffhttp://www.remotesensing.org/libtiff/

We have not heard of this before but it seems likely that the problem is due to attempting to close a file descriptor which is not currently open (either never been opened, or already been closed).  This could be due to a bug in libtiff or your application. You are going to need to debug this for yourself some more such as finding the call stack and arguments which lead to this situation.

## Re: Problem using libtiff in debug mode with visual studio 2010

 I've just noticed that the problem occures only when I try to open a Tif with custom tags. But I still have no idea why it works in Release and not in debug...

## Re: Problem using libtiff in debug mode with visual studio 2010

 Actually the failure occures just after I get the warning on the console: "red.Tif: Error fetching data for field "Tag 1808."", which is the warning I get when I open a tif file with custom tags. It doesn't stop the code when I am in release, but it does when I am in debug mode. Do you think libtiff in this case returns an error that isn't supported by visual studio in debug and causes its failure? Could I change it by some sort of other warning?

It's an assertion within the C library and those are not present in the release version. But the release C runtime probably still has code to quietly ignore the error instead of crashing. _______________________________________________ Tiff mailing list: [hidden email] http://lists.maptools.org/mailman/listinfo/tiffhttp://www.remotesensing.org/libtiff/

The answer to that is simple.  The release mode build disables assertion statements while the debug build enables them. You have provided us with remarkably little information.  Helpful information would include:   * The libtiff version you are using.   * Whether tif_win32.c or tif_unix.c is used for file I/O, or if you    are providing your own I/O support.   * A sample TIFF file which causes the problem.   * A debugger backtrace for when the problem occurs.

## Re: Problem using libtiff in debug mode with visual studio 2010

 Actually I can't use the last version of tifflib because I have to use visual studio 2010 (for historical reasons on the project I'm working on), so I  have to use a pre-2010 version of libtiff.

## Re: Problem using libtiff in debug mode with visual studio 2010

 The right way to compile libtiff is to go on the libtiff directory download and execute the following command line, right? nmake /f makefile.vc Is there anything else to do? Because I've been checking everything and I don't know why the last version can't work with my programm.

## Re: Problem using libtiff in debug mode with visual studio 2010

 I finally managed to build and install the latesr version of libtiff on visual studio 2010, but I still have exactly the same mistake in debug when I do a TIFFopen in debug mode. What I did to build libtiff is to use the command prompt of visual studio 2010, and executed the following command lines in the libtiff directory: nmake /f makefile.vc cleannmake /f makefile.vc DEBUG=1Do you know if there is something I am doing wrong here?Thank you,Emmanuel De : Bob Friesenhahn <[hidden email]> Envoyé : lundi 9 octobre 2017 13:39:35 À : Emmanuel Cosnard Cc : Roger Leigh; [hidden email] Objet : Re: [Tiff] Problem using libtiff in debug mode with visual studio 2010   On Mon, 9 Oct 2017, Emmanuel Cosnard wrote: > I am getting all these errors with the last version of libtiff: It looks to me like these issues have something to do with a mis-match between how libtiff was compiled and how the using application is being compiled.  The compilation options need to be compatible.

## Re: Problem using libtiff in debug mode with visual studio 2010

 Thank you very much Even, it's working perfect now! But it's not working anymore in release... Is there a way to make it work for both, or should I duplicate them, i.e one for debug and one for release?
