[Mono-list] New: cross-compiling with mkbundle

Sat Aug 20 03:24:34 UTC 2016

Hello,

The pull request is going through:

https://github.com/mono/mono/pull/3423

The only downside is that until we build new runtime binaries and post them to the server, the feature will not work (it will work with local builds though)

Hello,

1) Will the new cross-platform mode support embedding the machine config?

My program uses web connections which relies on the configuration in

machine.config, however when I bundle a program with:

mkbundle --cross {target} --machine-config {path-to-machine.config} ....

app.exe app-native

and then try to run the output, I get the following error:

Unknown stream on embedded package: machineconfig:

Apologies, this is a bug, I will fix it.

2) Cross-compiling for macOS from Linux produces an ELF binary, rather than

a Mac binary (Mach-0?).

Is this happening because I haven't specified a runtime, just a

cross-compilation target?

It is because I made a mistake.   You can either use Mono/master, or the stable mono branch, or if you do not want to, just run mkbundle and specify the --runtime option, and pass the file to your runtime, like this:

mkbundle --runtime ~/.mono/targets/4.4.0-macos-10.7-amd64/mono

Hi Miguel,

I have 2 questions about the new mkbundle:

1) Will the new cross-platform mode support embedding the machine config?

My program uses web connections which relies on the configuration in
machine.config, however when I bundle a program with:

mkbundle --cross {target} --machine-config {path-to-machine.config} ....
app.exe app-native

and then try to run the output, I get the following error:

Unknown stream on embedded package: machineconfig:

2) Cross-compiling for macOS from Linux produces an ELF binary, rather than
a Mac binary (Mach-0?).

Is this happening because I haven't specified a runtime, just a
cross-compilation target?

Thanks,
Patrick
