Varnish compiler will not start when providing correct .vcl file
I installed Varnish with command apt-get install varnish
Varnish version is varnishd (varnish-6.2.1 revision 9f8588e4ab785244e06c3446fe09bf9db5dd8753)
I try to validate my VCL file with command varnishd -C -f /etc/varnish/default.vcl
My VCL file:
vcl 4.0;
backend default {
.host = "127.0.0.1";
.port = "8080";
}
sub vcl_recv {
}
sub vcl_backend_response {
}
sub vcl_deliver {
}
This is the response I get, seems like it just echoes out varnish .c file:

However if I make a error in my VCL file, like replace .host with host, I get a VCC compiler error:
Message from VCC-compiler:
Expected '.' got 'host'
(program line 93), at
('/etc/varnish/default.vcl' Line 17 Pos 5)
host = "127.0.0.1";
----####---------------
In backend specification starting at:
('/etc/varnish/default.vcl' Line 16 Pos 1)
backend default {
#######----------
Running VCC-compiler failed, exited with 2
VCL compilation failed
Any ideas what am I doing wrong?

You're not doing anything wrong.
This is what the -C option does according to the docs:
Output VCL code compiled to C language
What you're seeing is the C representation of the VCL file. The VCC thread of the varnishd process will transpile the VLC code into C code. This C code will be compiled into machine code and the .so file that results from the compilation will be linked to the varnishd runtime process prior to execution.
As long as you're not making any syntax errors, the -C option will spit out the C code. Once you make a mistake in the VCL, the compilation will fail and you'll get an error.
VCL validation with varnishadm
There are other ways to validate your VCL file.
You can either add your VCL code as an inline string to varnishadm vcl.inline. See https://varnish-cache.org/docs/6.0/reference/varnish-cli.html#vcl-inline-configname-quoted-vclstring-auto-cold-warm for documentation.
You can also use the following commands to load, validate & discard the VCL file:
sudo varnishadm vcl.load validation default.vcl
sudo varnishadm vcl.discard validation
The first command will load the default.vcl file and try to compile it. When it success the validation configuration is stored and can be used in production through varnishadm vcl.use validation.
But we're not going to do that. Because this is only a validation run, we'll remove the validation config through varnishadm vcl.discard validation as seen in the example above.
