Hi,
I have never personally compiled Liblouis, but a typical problem if your
program cannot link is that there is a mismatch in the linker function
definitions.
One way was to provide a DEF file to the linker.
I don't know if this is the problem here, but it might be.
There was also a keyword something like _dllexport (it is a while since I made
a DLL using Visual C++).
In your own project, make sure that you have included the liblouis.lib file in
the link imputs.
Sorry this is vague, but I hope it might give some pointers.
With best regards,
James.

Dear Yuemei,
I applied your code and it compiles successfully but it's still with
error, no functions found from the dll when calling.

Hi, Phúc
I changed the static declaration of an array to malloc() and free() to
compile on Windows for liblouis 3.12 using Visutal Studio 2017.
Below is my slight change to the source code:
//=========================10/22/2019====================
//widechar dots[length]; //this causes compiler error on windows
widechar* dots = malloc(length * sizeof(widechar)); //replacng static buffer
if (dots != 0) {//if condition added 10/22/2019
for (unsigned int k = 0; k < length; k += 1) {
widechar c = text[k];
widechar d = _lou_getDotsForChar(c);
if (d == LOU_DOTS) d = _lou_charToFallbackDots(c);
dots[k] = d;
}
}
int iRetUpdatepos = for_updatePositions(dots, 1, length, 0, pos, input,
output, posMapping,cursorPosition, cursorStatus);
if (dots != 0) //if block added 10/22/2019
free(dots);
return iRetUpdatepos;
//=======================================================

Subject: [liblouis-liblouisxml] LibLouis DLL Compilation Errors
Dear All,
I have some errors when compiling LibLouis 3.12 and 3.13 into LibLouis.dll
for windows. I have followed the instruction in source folder to compile with
Microsoft community 2017. Can you help examine the errors below and advices,
please?
I have no problem to compile 3.6 version but with 3.12 and 3.13, it has the
error:
..\liblouis\lou_translateString.c(2254): error C2057: expected constant
expression
..\liblouis\lou_translateString.c(2254): error C2466: cannot allocate an
array of constant size 0
..\liblouis\lou_translateString.c(2254): error C2133: 'dots': unknown size
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual
Studio\2017\Community\VC\Tools\MSVC\14.16.27023\bin\HostX86\x86\cl.EXE"'
: return
code '0x2'
Then, I checked with the code and see it stucks at the line: widechar
dots[length];
I changed to: widechar dots[1024];
Now it can compile successfully and got the Liblouis.dll for all 3 versions,
3.6, 3.12 and 3.13. However, when calling functions like lou_translateString
and others, it informs cannot find the function.
I have tried to compile with both Microsoft community 2017 and 2019, both
have the same errors.
Thanks in advance and look forward to your help.
