Hi I have a hard time getting ironruby to build on OSX I first tried with the dmg image I can download from the mono-project. After I tried with building mono from subversion. Am I missing something obvious ? ivan-mbp:ironruby ivan$ rake compile mono=1 (in /Users/ivan/tools/ironruby) Read in 47 resources from ‘/Users/ivan/tools/ironruby/src/microsoft.scripting/Resources.resx’ Writing resource file… Done. Read in 17 resources from ‘/Users/ivan/tools/ironruby/src/microsoft.scripting/Math/MathResources.resx’ Writing resource file… Done. error CS0006: cannot find metadata file `mono/2.0/System.Configuration.dll' error CS0006: cannot find metadata file`mono/2.0/System.dll’ Compilation failed: 2 error(s), 0 warnings rake aborted!

The last time I built IronRuby on a OS X I grabbed Mono from the SVN trunk - the dmg was really out of date. -John ---

I did i’m trying to compile it against the mono version i got from trunk from yesterday ivan-mbp:ironruby ivan$ mono -V Mono JIT compiler version 1.9 (/trunk/ r94512) Copyright (C) 2002-2007 Novell, Inc and Contributors. [www.mono-project.com](http://www.mono-project.com) TLS: normal GC: Included Boehm (with typed GC) SIGSEGV: normal Notification: Thread + polling Architecture: x86 Disabled: none ok … I’ll keep trying then until I get a working mono version. Haven’t done much testing with mono but I did run the minimal test suite before installing. If I compile on windows and use the binaries there is no problem. Thanks Ivan ---

Are you compiling with both --with-preview=yes and --with-moonlight=yes ? Actually, I think they both are set to yet by default, but if you’re building from SVN you’ll need to checkout not only the mono directory but olive, moon, mcs, and (possibly) gtk-sharp as well. You’ve already got mono checked out, so if you enter the same directory that the mono directory is contained in and run, svn co svn://anonsvn.mono-project.com/source/trunk/{mcs,moon,olive,gtk-sharp} … to then svn up mono you can then enter the mono directory and run, ./autogen.sh --with-preview=yes --with-moonlight=yes [additional options (such as --prefix)] NOTE: I realize I mentioned that I believe both of these values are yes by default, but it doesn’t hurt so it’s worth adding them just in case. If that script finishes without erroring out then run, make; sudo make install If it does error out there’s a good chance it’s going to be one of several things, 1. The existing DMG-based installation is getting in the way. I would move /Library/Frameworks/Mono.framework (if you don’t see it there, try ~/Library/Frameworks/Mono.framework) to another directory to ensure you’re not running into a problem with the build process linking against the wrong libraries. 2. The generated ./configure file will have a few lines that autotools will claim to be invalid syntax. If you see this problem, just open the ./configure file, go to the specified line, and comment it out. IMPORTANT!: Don’t rerun ./autogen.sh at this point. It will write over the previous generated ./configure file and cause the same error to occur. At this stage of the game you’ll then want to run, ./configure --with-preview=yes --with-moonlight=yes [additional options (such as --prefix)]; make; sudo make install At this point you’re system should be completely up-to-date with all of the latest code that is specific to the needs of the DLR and DLR-based languages. That doesn’t mean it’s guaranteed to compile and work, but I’ve yet to find a situation unrelated to System.Windows.Forms that didn’t work on OS X if it worked on Linux. It sometimes takes a bit of hacking the build process, but it usually works out in the end. 😃 That said, given the IronRuby and the DLR are moving targets, there’s no guarantee you’re not going to run into issues. But in my own experience, the Mono team places an extremely high importance on bugs related to the Iron\* projects and the DLR. Often times there’s a fix checked into SVN within a few hours of filing the report. Hope this helps! – /M:D M. David P.

I’ve got it working now. Thanks for all your help :). Turns out I have to set a variable PKG\_CONFIG\_PATH in .bash\_profile that includes the path which has the mono.pc file in it. I don’t have to edit anything anymore and it compiles Thanks Ivan ---

Thanks guys, I got it to build. I do feel slightly dirty because it’s somewhat hacky. (I’m very, very new to OSX) but I edited the Rakefil and set the libdir specifically there FRAMEWORK\_DIR = ‘/opt/local/mono/lib/mono/2.0/’ #Pathname.new(libdir) + ‘mono’ + ‘2.0’ I’m not entirely happy with this solution and it probably has something to do with an environment variable not being set correctly, but at least i know it can be done now and eventually I’ll get it so that the standard rake file suffices. I’ve seen that the command ‘pkg-config --variable=libdir mono’ doesn’t return anything, which may be the cause 🙂 Cheers Ivan ---
