We tried adding --config /etc/mono and got a segmentation fault when we tried
to run the exe. However I got in contact with Alex via IRC and he suggested
removing everything but the libc entry in the config file. This appears to have
worked!
Here is what our final mkbundle command looked like:
mkbundle --static --deps --config /workspace/output/configtest --machine-config
/etc/mono/4.5/machine.config Integrate.Identity.Gateway.exe (all dlls with full
paths, space separated) -o identity.exe
contents of “configtest” config file (we copied /etc/mono/config and removed
everything but libc to make this file):
<configuration>
<dllmap dll="libc" target="libc.so.6" os="!windows"/>
</configuration>

to make executable
You’re missing the dllmaps that remap „libc“ in p/invoke declarations to
libc.dylib/libc.so.6/msvcrt.dll, so the program doesn’t find the library.
Pass --config /etc/mono/config to use the default dllmap config that ships with
Mono (after verifying the entries make sense for your target).

We're being slowly driven nuts by this <OutlookEmoji-&#X1f60a.png>
We finally got mkbundle --static to build a single executable of our
microservice, but when we move it to another machine, it fails to run unless we
install mono-core (this is all on Cent0S 7 installs).
I've included the error below, but it appears to be MassTransit library
specific while the issue gets resolved with installing mono-core (yum install
mono-core). This leads us to believe there is some other issue at hand and the
error is misleading.
Our mkbundle command:
mkbundle --deps --machine-config /etc/mono/4.5/machine.config --static

Does anyone have any pointers on what we can try next? We've spent a few days
on this at this point and are at a dead end.
We use bindingredirect in our app.config if that matters.
Thanks,
Eugene
