Failed to build library on Windows about libopencad HOT 9 OPEN

I do not have any Windows machine nearby, so it will take some time for investigation. Thanks for your report.

I had the same issue here, I could use cmake against it.
make didnt work for me, so I launched the sln in vs.
Linked the library and it was filled with errors.

I've got laptop with Windows, so will fix the build in a next few days. Thanks for your patience.

Hi,

I just wanted to follow up, how far are we off this fix?

hi,

I manage to compile libopencad.dll on windows with mingw64 and msys. I have just modify one line in cadheader.cpp, in fact unix is a macro on windows so in funciotn addValue (line 470) :
`int CADHeader::addValue( short code, long julianday, long milliseconds )
{
// unixday -> julian return ( unixSecs / 86400.0 ) + 2440587.5;
// julian -> unixday return (julian - 2440587.5) * 86400.0

double seconds     = double( milliseconds ) / 1000;
double unixday        = ( double( julianday ) - 2440587.5 ) * 86400.0;
time_t fullSeconds = static_cast<time_t>(unixday + seconds);
return addValue( code, CADVariant( fullSeconds ) );

}`

install CMake for windows then, in libopencad directory

C:/CMake/bin/CMake.exe -DBUILD_SHARED_LIBS=ON -G "MSYS Makefiles" CMakeLists.txt
then
make

It works for me, compilation is ok, link also, i have not tested runtime...

@sandyre Thank you for releasing this library. Like previous posters on this thread I cannot compile the VS Studio project generated by cmake. I get the same errors as this post. Is there a plan to fix this bug? Thanks.
