Hello David
After one day rest, my condition rather better so that I can think about this
with cool head.
Cannot src/Makefile in the fixed package come back before for mingw/cygwin pat
without affective for
Unix build ?
My previous patch works correctly.
Using previous the Makefile that I made a patch before , the fixed.oct linked
the following
Linking fixed.oct

-Wl,--enable-runtime-pseudo-reloc -o

Creating library file: liboctave_fixed.dll.a

You need some additional compile flags. ==> You need liboctave_fixed.dll.a

-shared -Wl,--export-all-symbols -Wl,--enable-auto-import
-Wl,--enable-runtime-pseudo-reloc
--enable-auto-import -Wl, --out-implib=liboctave_fixed.dll.a
The flag make it possible fixed.oct behaves as a dynamic link libraries.
Perhaps the MSVC case is similar, the difference is that the import lib is
automatically generated by
MSVC as the Michael suggestion. This was suggested in the long discussin with
me, you and Michael.
I confirmed this like following
cd ../examples
make
The make failed at the link, I manualy linked
g++ -shared -Wl,--export-all-symbols -Wl,--enable-auto-import
-Wl,--enable-runtime-pseudo-reloc -o

-L../ -> -L/home/octaves/fixedSVN/fixed-0.7.5/src
After that
octave
addpath ("../src")
a = ffft(fixed(6,4,32*randn(64,1)))
The window messages said that the dynamic link libarary fixed.oct was not
found.
(in reality it was represented in Japanese)
Please note that the exetention dll is not required for the windows dynamic
link library.
Then
export PATH=/home/octaves/fixedSVN/fixed-0.7.5/src:$PATH
octave
addpath ("../src")
a = ffft(fixed(6,4,32*randn(64,1)))
a =
