... it might have happened due to the removal of the "slirp" submodule
from the git repository. For example if you see an error message like this:
Parameter 'type' expects a netdev backend type
this likely means that the "user" mode backend type is not available in
your binary anymore. To fix it, simply install "libslirp-devel" (or
libslirp-dev or however it is called) from your OS distribution and
recompile.
Thanks for the hint Thomas. I'm afraid many developers will miss your
email.
Jason, Marc-André, could we improve the buildsys check or display
a more helpful information from the code instead?
It looks to me we need to improve the build.
I'm not sure there is anything to improve in the build system -
configure/meson.build are just doing what they should: Pick the default
value for "slirp" if the user did not explicitly specify "--enable-slirp".
But the error message is not very helpful. It should rather say something
like (partly suggested by Daniel in IRC yesterday already):
Type 'user' is not a supported netdev backend by this QEMU build. Please
check the spelling or whether it has been enabled at compilation time.
... or something like this.
Someone interested to write a patch?
Thomas
