Hello, cygwin users
this might be some odd question, but I'm hoping that someone out there
had some experience with compiling C code for Java Native Interface.
This is what I'm trying to do: I have a simple C function that I want to
port to Java with Native Interface. According to the Java instructions,
I need to compile the code into a dynamically loaded library. Doing it
for Solaris works perfectly with (my code is in a file called Clock.c as
you can see):
gcc -I/usr/j2se/include -I/usr/j2se/include/solaris Clock.c -o
libClock.so
I've asked a friend who has Microsoft Visual Studio to do the same for
Windows, and it all went well. The command he used is:
cl -Ic:\jdk\include -Ic:\jdk\include\win32 -LD Clock.c -FeClock.dll
He than has sent me that dll and it works perfectly.
I've tried to build the library with cygnus according to the
instructions in the manual. The dll I get doesn't seem to work.
Please, if someone had any experience could you send me some
instructions how to do that.
Thanks,
Miroslav
