Bugzilla Automation <bugzilla@FreeBSD.org> has asked freebsd-mono mailing list <mono@FreeBSD.org> for maintainer-feedback: Bug 229710: lang/mono: port to aarch64 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229710 --- Description --- I don't know why I did this, I'm not even planning to use .NET on my RPi3, I guess it was just bothering me that it worked on armv7 and not aarch64… (also I needed to do something in parallel while Crystal was compiling on the ThunderX I rented from packet.net) Hopefully I didn't screw anything up (I was modifying the port as errors appeared, did not clean and rebuild from scratch — it's slow and access to a ThunderX is expensive… honestly it's not much faster than RPi here because of an issue described below) The Roslyn C# compiler has a concurrency problem on aarch64: https://github.com/mono/mono/issues/7017 (not FreeBSD specific) so the workaround is to disable parallelism… so the .NET libraries are built very very slowly :( BoringSSL patch is from bug 223019 but slightly modified (to ignore <sys/auxv.h>), see comment in that thread. Also there was an intermittent jemalloc error, had to restart the build once: <jemalloc>: /usr/src/contrib/jemalloc/include/jemalloc/internal/extent_inlines.h:63: Failed assertion: "szind < NSIZES" ================================================================= Got a SIGABRT while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application. ================================================================= gmake[14]: *** [../../../build/library.make:342: ../../../class/lib/net_4_x-linux/Facades/System.IO.FileSystem.Primitives.dll] Abort trap (core dumped)
