Hi, I am the maintainer of Mono and I want to add some (maybe useful) information that may help into fixing this problem or at least understanding it. (Warning: I am not a porter, and I do not know the internals of Mono) This build problem of Mono is a runtime problem that only occurs on elara, netwinder, europa and smackdown. During the build of Mono (it's a runtime which bootstraps it fails on only those machines at runtime stage. It first builds the JIT (Just In Time compiler) which translates the CIL bytecode (*.exe or *.dll) into the ASM instructions. Then the C# compiler (mcs) that is used during boostrap is running on top of that runtime, so if the JIT emits instructions that doesn't work correctly on that CPU it will fail in pretty random ways, currently seen as SIGSEGV, SIGABRT or an FileNotFoundException (which is bogus btw). So what we see in the build logs of Mono, is that the application mcs.exe which runs on top of the JIT crashes. This issue is filed upstream under: http://bugs.ximian.com/show_bug.cgi?id=78183 Here a report of builds that worked and builds that failed: FAIL ---- elara: SIGSEGV http://buildd.debian.org/fetch.cgi?pkg=mono&arch=arm&ver=1.1.18-3&stamp=1161343362 netwinder: SIGSEGV http://buildd.debian.org/fetch.cgi?pkg=mono;ver=1.1.18-1;arch=arm;stamp=1161112787 netwinder: SIGABRT http://buildd.debian.org/fetch.php?&pkg=mono&ver=1.1.17.1-4&arch=arm&stamp=1159074469&file=log&as=raw europa: SIGABRT http://buildd.debian.org/fetch.cgi?&pkg=mono&ver=1.1.17.1-2&arch=arm&stamp=1157817237&file=log smackdown: SIGABRT http://buildd.debian.org/fetch.cgi?&pkg=mono&ver=1.1.17.1-1&arch=arm&stamp=1157335424&file=log FAIL of packages that use the Mono runtime (this shows its not a problem of the compiler but runtime): europa: Unhandled Exception: System.IO.FileNotFoundException: RSS.NET http://buildd.debian.org/fetch.php?&pkg=blam&ver=1.8.2-2&arch=arm&stamp=1152341997&file=log&as=raw elara: Unhandled Exception: System.IO.FileNotFoundException: mscorlib.resources http://buildd.debian.org/fetch.php?&pkg=ikvm&ver=0.28.0.0-1&arch=arm&stamp=1154063310&file=log&as=raw europa: Unhandled Exception: System.IO.FileNotFoundException: evolution-sharp http://buildd.debian.org/fetch.php?&pkg=evolution-sharp&ver=0.11.1-1&arch=arm&stamp=1149043910&file=log&as=raw SUCCESS ------- toffee: http://buildd.debian.org/fetch.cgi?pkg=mono;ver=1.1.18-3;arch=arm;stamp=1161939692 toffee: http://buildd.debian.org/fetch.cgi?pkg=mono;ver=1.1.17.1-5;arch=arm;stamp=1159948410 cats: http://buildd.debian.org/fetch.cgi?pkg=mono;ver=1.1.17.1-4;arch=arm;stamp=1159460374 cats: http://buildd.debian.org/fetch.cgi?&pkg=mono&ver=1.1.17.1-3&arch=arm&stamp=1158536080&file=log smackdown: http://buildd.debian.org/fetch.cgi?&pkg=mono&ver=1.1.13.8-1&arch=arm&stamp=1152124452&file=log toffee: http://buildd.debian.org/fetch.cgi?&pkg=mono&ver=1.1.13.6-4&arch=arm&stamp=1147240675&file=log toffee: http://buildd.debian.org/fetch.cgi?&pkg=mono&ver=1.1.13.6-3&arch=arm&stamp=1147640592&file=log toffee: http://buildd.debian.org/fetch.cgi?&pkg=mono&ver=1.1.13.6-2&arch=arm&stamp=1145751188&file=log toffee: http://buildd.debian.org/fetch.cgi?&pkg=mono&ver=1.1.13.4-1&arch=arm&stamp=1142684613&file=log toffee: http://buildd.debian.org/fetch.cgi?&pkg=mono&ver=1.1.13.2-1&arch=arm&stamp=1138914220&file=log cats: http://buildd.debian.org/fetch.cgi?&pkg=mono&ver=1.1.13.1-1&arch=arm&stamp=1137330496&file=log toffee: http://buildd.debian.org/fetch.cgi?&pkg=mono&ver=1.1.12.1-1&arch=arm&stamp=1136143915&file=log We can see here, that the same upstream version and same debian revision, show different results between netwinder model and cats model: it builds on cats and fails on netwinder (see 1.1.18-3 and 1.1.17.1-4). As said I am not a porter, so I don't know the difference between cats and netwinder, but AFAIK cats is v4l and netwinder is v3l. Upstream tests and only has access to arm v5l and can't reproduce this problem, as seen in the upstream bugreport. Hope this helps. -- Regards, Mirco 'meebey' Bauer PGP-Key: http://keyserver.noreply.org/pks/lookup?op=get&search=0xEEF946C8 -----BEGIN GEEK CODE BLOCK----- Version: 3.12 GIT d s-:+ a-- C++ UL++++$ P L++$>+++$ E- W+++$ N o?
