Fork of QD (2.3.17) dll
c_test.c from it & QD.dll & QD.lib import library.

EDIT: missing headers and libs added.
EDIT  QDSSE.dll for 32-bit.
May the source be with you

That looks very interesting, thanks ;-)

The *.lib files are just import libs. How useful is that, if you need the DLL anyway?

TimoVJL

Because it is C++ code, dll is obvious choice.

hello TimoVJL
is there a way for you to compile the 32-bit version using sse?,  then you won't have to worry about fpu_fix_start/fpu_fix_end.
I edited the makefile in QD-master\src and added -mfpmath=sse -msse2 to CPPFLAGS = -O2 -mfpmath=sse -msse2
but that's when using gcc, not sure how you would do that in PellesC.
btw, that's a very small-sized dll, only 115k, mine compiled with gcc was 1.2 meg even after stripping.

TimoVJL

It was compiled with msvc 2010 with dynamic dlls.
It uses msvcp100.dll.

I added SSE version, with cl option -arch:SSE too.
May the source be with you

unfortunately it's still using the fpu.

TimoVJL, did you have to edit any of the source files in order for vs to compile the project?
I have visual studio 2013-pro and also later community editions but am not able to setup a dll project that will compile
I have an older project, qd-2.3.7 and the 32-bit version compiles ok but if I replace the source files with the newer version then I have problems, something like max is not defined in the namespace std and can't convert qd_read to int.

jack

thank you
but still the same problem when using vs-2013
Quote
src\qd_real.cpp(446) : error C2039: 'max' : is not a member of 'std'
src\qd_real.cpp(446) : error C2440: '=' : cannot convert from 'qd_real' to 'int'
I have vs-2010 somewhere.

TimoVJL

so you have to add#if _MSC_VER >= 18
#include <algorithm>
#endif
to dd_real.cpp and qd_real.cpp
May the source be with you

jack

you are the man  :)
works like a charm, thank you.

jack

tank you TimoVJL  :)
having a C version means we can have a static lib instead of a dll, will keep an eye on your progress.

hello TimoVJL :)
just for fun I tried to compile the source files with gcc and there are no complaints, however if I try to compile to dll then there are three errors
undefined reference to `c_dd_error'
undefined reference to `c_dd_div_d_dd'
undefined reference to `dd_real_eps'
