Ticket #753
by Alexander v. Below 09 Jul '10

09 Jul '10

Hello, we are using MacRuby to run a Webrick server, and I would like to know if there is any help I can offer with issue 753. (1) I will gladly dive into the source, but it would make things a lot easier if somebody -- who knows the project better than me -- had a suspicion where I should look. If sending beer, coke or cookies helps, I will gladly do that, too. (MacRuby .5 works, but is unstable when using webrick). Thanks a lot Alex http://www.macruby.org/trac/ticket/753

Debugging MacRuby?
by Alexander v. Below 09 Jul '10

09 Jul '10

Hello, dear list, allow me another stupid question: I want to go into MacRuby's guts, and throw gdb at it. Attempting to look at issue #753, I did the naive thing: % gdb macruby (gdb) break dispatcher.cpp:1343 The answer here was: "No symbol table is loaded. Use the "file" command. Make breakpoint pending on future shared library load? (y or [n]) y Breakpoint 1 (dispatcher.cpp:1343) pending." Question 1: Do I need to build MacRuby differently to get a symbol file? Or is it just hidden away somewhere? When I continue: (gdb) run test_webrick.rb After a while, what I get is: [2010-07-09 19:42:21] ERROR Errno::EINTR: Interrupted system call - select(2) failed /Library/Frameworks/MacRuby.framework/Versions/0.7/usr/lib/ruby/1.9.2/webrick/server.rb:83:in `block' Which is way off from the error I would expect. If I do not try to set a breakpoint, I get the expected console output ("Assertion failed: ((b->flags & flags) == flags), function rb_vm_prepare_block, file dispatcher.cpp, line 1343."), and a SIGABRT. The backtrace looks, well, not really nice. Question 2: Am I even approaching this right? Or do I need to take special precautions? Thanks a lot Alex

llvm-config?
by Alexander v. Below 09 Jul '10

09 Jul '10

Hello, I am attempting to build MacRuby-trunk (rev 4338), and when I call rake I get the error: "The llvm-config executable was not located as /usr/local/bin/llvm-config. Please make sure LLVM is correctly installed on your machine and pass the llvm_config option to rake if necessary." Can I remedy this for Developer Tools installation of llvm (4.2), or is the only way to get rid of this to use the llvm version indicated in the readme? Thanks Alex
