Hi people, I have been able to get .so file which I'm trying to use now in a jni link in windows, but I'm facing some problems. This is the situation: I had some .cpp, .h and .lib libraries. My aim was to get a .so from these so that it can be used in a jni link in linux, so I used cygwin. Initially, these files were used to get a dll which talked to java programs in windows. Now the java program is ported to linux. However even though i use the same jvm, it cannot work since the java needs the dll. In linux the equivilent of a dll is .so in a jni link. So, after having obtained the .so by compiling the files in cygwin like this: g++ *.o scdll32.lib -o scard.so, i initially got an undefined reference to _WinMain@16. Having read from somewhere in the mialing list, I put an empty main() in one of the .cpp file and the .so is produced.
Then I ported it to Linux and tried to run my java program, but then get the following: java.lang.unsatisfiedLinkError:/folder path/scard.so:invalied ELF header Can anyone help me here...
