[Sawyer Liu]

 Thanks.

Hello Berto,
   I think you meant the “libssl-dev” should be installed, not 
“lib-sshdev”, right? I have installed libssl-dev, the result is same, cannot 
compile qemu.
   Thanks.

I think the thing is that it seem to compile fine on systems other than Ubuntu 
18 that have libssh installed so the problem is presumably with that particular 
version of Ubuntu rather than QEMU.

Can you make sure that the "lib-sshdev" package is installed and up to date on 
your system?

I can compile on my Debian 10 system with no problems.

Good luck!

The only feature that compiling QEMU with libssh adds is support for a 'ssh' 
block backend. That means you can pass '-drive file=ssh://host/path/to/file' to 
get QEMU to open a disk image on a remote machine.

If you don't need to use that feature, you can pass QEMU configure 
"--disable-libssh". QEMU will then just not try to use the Ubuntu libssh.

There seems to be some confusion in this thread about whether the problem is 
libssh or libssl. These are two different libraries. The bug report you give 
the URL for is for libssh.

thanks

Hi,

it is written in the email you quoted:
you can pass QEMU configure "--disable-libssh".
