Trying to cross-compile a compute node binary of Ruby1.9. First, the configure.in file is still broken from Ruby1.8.6. You need to comment out these lines so the configure script doesn’t break: ./configure.in:706:#AC\_FUNC\_GETPGRP ./configure.in:707:#AC\_FUNC\_SETPGRP You also need to hack the resulting configure file so it won’t exit complaining you are trying to cross compile. I used the following configure options: export CC=blrts\_xlc export F77=blrts\_xlf export FFLAGS=" -O2" export CFLAGS=" -O2" #Make sure to link the lmsglayer,lrts,ldevices before and after everything in the makefile. export LDFLAGS=" -qarch=440d -qtune=440 -lc -lnss\_files -lnss\_dns -lresolv -L/bgl/BlueLight/ppcfloor/bglsys/lb -lmpich.rts -lmsglayer.rts -lrts.rts -ldevices.rts" echo “Configuring” export EXTLIBS="-lc -lnss\_files -lnss\_dns -lresolv" ./configure -build powerpc-aix -host ppc-linux-gnu –includedir=/home/crb002/include --oldincludedir=/home/crb002/include –prefix=/home/crb002/ Now for the make: > make > ./lib/fileutils.rb:1532:in `public': undefined method`commands’ for > class `Module' (NameError) from ./lib/fileutils.rb:1532 from ./lib/fileutils.rb:1531:in`each’ > from ./lib/fileutils.rb:1531 > from ./mkconfig.rb:10:in `require’ > from ./mkconfig.rb:10 > make: \*\*\* [.rbconfig.time] Error 1 > make -n > ruby -I/MY\_FANCY\_PATH/ruby -rfake ./mkconfig.rb > -timestamp=.rbconfig.time > -install\_name=ruby > -so\_name=ruby rbconfig.rb > ruby -I/MY\_FANCY\_PATH/ruby -rfake -I. -rrbconfig > ./tool/compile\_prelude.rb ./prelude.rb ./gem\_prelude.rb prelude.c > blrts\_xlc -O5 -qarch=440d -qtune=440 -I. -I.ext/include/powerpc-linux > -I./include -I. -DRUBY\_EXPORT -D\_GNU\_SOURCE=1 -c prelude.c > make: \*\*\* No rule to make target `thread_.h', needed by`error.o’. > Stop.

Seems pthread isn’t supported, or isn’t detected properly. ---

For Ruby1.8 I just hacked the configure script to comment out offending lines, but it would be nice if the configure.in file was modified to get rid of cross compiling problems. > > > make > > > ./lib/fileutils.rb:1532:in `public': undefined method`commands’ for > > > class `Module’ (NameError) > > How is MINIRUBY defined in Makefile? MINIRUBY = ruby -I/MY\_PATH/ruby -rfake $(MINIRUBYOPT) RUNRUBY = $(MINIRUBY) -I`cd $(srcdir)/lib; pwd` Is miniruby anything special or can I just replace it with a working ruby1.8.6 build? > > blrts\_xlc -O5 -qarch=440d -qtune=440 -I. -I.ext/include/powerpc-linux > > -I./include -I. -DRUBY\_EXPORT -D\_GNU\_SOURCE=1 -c prelude.c > > make: \*\*\* No rule to make target `thread_.h', needed by`error.o’. > > Seems pthread isn’t supported, or isn’t detected properly. Yes. The compute nodes of Blue Gene/L use a very stripped down kernel that makes everything run in one process. No forking allowed, no pthreads. Is there something I have to pass in order to turn off OS threading? For ruby1.8 this wasn’t a problem. ---

So if one wanted to do this what would be involved? ---
