getting dart2native Linux executables running on FreeBSD

dart2native-on-freebsd.md

I used a FreeBSD 11 VM runing on GCE

To get Linux exe's working on BSD

• compile with dart2native, eg I used DSG from a zip of exe's built here: https://github.com/maks/dsg/actions/runs/198892581
• sudo brandelf -t linux exe-filename
• edit /etc/rc.conf and add: linux_enable="YES"
• then: sudo service abi restart
• cd /usr/ports/emulators/linux_base-c7 then make install
• go back to where you have your dart2native linux exe and run it

For some reason the dart2native exe runs the Dart VM but doesn't run the aot snapshot thats embedded in it. eg. I see:

$ ./dsg
Usage: dart [<vm-flags>] <dart-script-file> [<script-arguments>]

Executes the Dart script <dart-script-file> with the given list of <script-arguments>.

Common VM flags:
--enable-asserts
...

I'm not sure why that's happening but I ran out of time to investigate further, but it does seem to demonstrate to me that the Linux DartVM thats generated for dart2nativeseems to be able to run on FreeBSD 11 with its Linux x64 compat layer.

Boy, if you ever get this working, I'd be interested too. And beware, dart2native has been replaced in mostly name only with dart compile exe.
