Hi, I created a new port for mongodb49: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=254631 It compiles fine: https://www.klop.ws/mongodb49-4.9.0.r0.log When I run an application I get "Illegal Instruction" error. ============================================================== [root@rpi4 /tmp]# lldb /usr/local/bin/mongo (lldb) target create "/usr/local/bin/mongo" Current executable set to '/usr/local/bin/mongo' (aarch64).

I disabled it on my build system because of lack of memory. Can anybody help me with this? It would be interesting to know if this also happens on amd64. Regards, Ronald.

If I grep correctly, rpi4 is ARMv8-A. Yet you're compiling with -march=armv8.2-a, so it's a case of wrong -march.
