Description of problem: Installing Arduino on a 32-bit system crashes on startup due to bug in finding JNI library. Even on 32-bit systems attempts to How reproducible: Always Steps to Reproduce: Install 32-bit Fedora (I believe this is also true for 24, but only tried on 23). Run arduino from a terminal. See arduino crash with JNI complaint about not finding the 64-bit astyle library. Additional info: I believe the problem is in the RPM patch "arduino-use-system-astyle.patch". It has the following code: + File libdir = new File("/usr/lib64"); + String astylePath; + if (libdir.exists() && libdir.isDirectory()) { + astylePath = "/usr/lib64/libastyle.so"; + } else { + astylePath = "/usr/lib/libastyle.so"; + } 32-bit systems *do* have the /usr/lib64 directory, even though it doesn't have anything installed in them. Therefore, the "true" branch will always be taken, and it will look for the 64-bit library instead of the 32-bit one. I am not very familiar with Java and JNI, but I think you should check for the file itself. You can probably change that to: + File libfile = new File("/usr/lib64/libastyle.so"); + String astylePath; + if (libfile.exists()) { + astylePath = "/usr/lib64/libastyle.so"; + } else { + astylePath = "/usr/lib/libastyle.so"; + }
