Fork of QD (2.3.17) dll

[TimoVJL]

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.

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.

thanks you

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.

[jack]

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.

[TimoVJL]

No.
build cmd attached.

[jack]

thank you
but still the same problem when using vs-2013

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

Code: [Select]

#if _MSC_VER >= 18
#include <algorithm>
#endif to dd_real.cpp and qd_real.cpp

[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.

[jack]

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'

[jack]

thank you
