Paulw.torchtrust signaturePaul and I had a private conversation to track down
the problem with the compilation of liblouis.dll release version 3.0.0 for
Windows.
The result was that the release version compiles correctly with MS Visual
Studio 2015 (older compiler versions may have problems), provided that the file
windows/liblouis.def is changed:
The last two lines with the names lou_findTable and lou_indexTables should be
removed.
This has already been done in the github master and will be corrected in the
next release.
These function names belonged to findTable.c and were the cause of an error in
the compilation. To solve this I added the name of the existing file
findTable.c to makefile.nmake which caused more errors. This file is not
necessary for a normal use of liblouis.dll.
In addition: In the meantime I tested liblouis.dll version 3.0.0 and an older
version of liblouisutdml.dll with our program TactileView. This seems to work
alright.

Windows (MS Visual Studio)
In reply to your previous email, I have got liblouis 3.0.0 working with
liblouisutdml, well I did before my latest updates to that pull request, but I
don't see why there should be a problem with the changes I made. If you want my
project files, I'm happy to let you have them. I had to build various
dependancies, If I remember right, so never got the 64-bit version working of
liblouisutdml.

Since the compiler that I used was a rather old one, I installed Visual
Studio Community 2015 and some of the peculiarities seem to have gone (unless I
already solved them).
For strndup, which is not supported by this and other MS compilers (only
strdup is supported), I added a replacement from
http://opensource.apple.com//source/gcc/gcc-5666.3/libiberty/strndup.c.
It now compiles to liblouis.dll.
I will further test tomorrow.
In conclusion the files in de Windows section still need some improvement.

Subject: [liblouis-liblouisxml] Compilation problem with new findTable.c in
Windows (MS Visual Studio)
I am trying to compile LibLouis 3.0.0 in Windows with MS Visual Studio.
Initially I solved a few minor problems.
Then I found that the new component findTable.c (added by Bert Frees 2015?)
was not added to windows\makefile.nmake.
After I changed makefile.nmake, the compiler could not find dirent.h.
It seems dirent.h is not supported normally by Visual Studio, but is included
in the MinGW compiler. There is a version of dirent.h available via
http://softagalleria.net/dirent.php that can be used with Visual Studio.
After I copied it, I tried to compile again, but this time the compilation of
findTable.c gave several problems, that I list at the end of this message.
At the moment I cannot solve these compilation problems easily.
For reference, the first error appears in line 98 with the contents:
List * l3 = malloc(sizeof(List));
Before I dive into these problems further:
Is findTable.c a necessary part of LibLouis.dll?
If not, is there an easy way to remove this part or replace it by a stub?
Has anyone tried to combine LibLouisutdml yet with version 3.0.0?
If I cannot solve these problems shortly I will have to stick with version
2.6.5 (actually I am still using 2.6.4) for our next release of TactileView.
Best regards,
Arend Arends
