Hi all, I was able to run my Java-R program using a 32-bit jdk on my 64-bit machine; however I wish to use the 64-bit jdk so my Java program can take advantage of the larger memory capabilities etc. I'm currently trying to compile JRI_0.4-1 on a 64-bit XP I got to a point that I was able to generate a 32-bit dll, but I don't know exactly how to modify it so that it's able to generate a 64-bit dll. I tried modifying the makefile adding -m64 to some of the gcc command with no success. I am not very experienced with creating dll's, but I was wondering if anybody attempted to compile a 64-bit JRI.dll? And if so what type of modifications or resources should I use? Thanks!
