For the plugin itself: various builds of gcc-bridge.so are shipped with the gcc-bridge compiler jar and extracted to a temp folder as needed. We have builds for linux-x86 and linux-i686, and I know that we have contributors who have built a version for os x. Windows remains unattempted...
GCC needs to be installed, and on 64-bit system, gcc-multilib also needs to be present so we can generate code that uses 32-bit pointers, as GCC-Bridge backs pointers with JVM arrays which support only 32-bit (31-bit I guess) indexing on all platforms. On Ubuntu, you'd need: sudo apt-get install gcc-4.6 gfortran-4.6 gcc-4.6.multilib For Renjin, packages are distributed as JARs so we run a build server (http://packages.renjin.org) that churns out pre-built JARs for all the R packages in the major R repositories. I don't know if would be possible to do something similar for JRuby. -Alex On Tuesday, February 2, 2016 at 2:31:01 AM UTC+1, Charles Nutter wrote: > > On Mon, Feb 1, 2016 at 11:55 PM, Alexander Bertram > <al...@bedatadriven.com <javascript:>> wrote: > > You can basically tell the compiler to map a C struct to a given java > class, > > for example, mapping CRuby's VALUE to org.jruby.RubyBasicObject and > import > > > > GimpleCompiler compiler = new GimpleCompiler(); > > compiler.addRecordClass("__VALUE", RubyBasicObject.class); > > compiler.addMethod("TYPE", CRuby.class, "TYPE"); > > > > You can then define: > > > > class CRuby { > > public static int TYPE(RubyBasicObject obj) { > > if(obj instance of RubyBoolean) return 1; > > if(obj instance of RubyHash) return 2; > > // etc... > > } > > } > > Very nice!
