Hi, on macOS Catalina 10.15.7 I tried to upgrade openssh port and it fails as following:

Please attach full log file.

Errors with implicit declarations are an issue when the using the latest version of Xcode for Big Sur and Catalina.

However, I've got this version of openssh installed under Big Sur, so there is something else going on on your machine.

sure, the log is attached.

It looks like this gets introduced by the following patch: openssh-8.1p1-gsskex-all-20141021-mp-20201216.patch

comment:4 Changed 4 years ago by Schamschula (Marius Schamschula)

In dbf07b3da095588d8578fa663a51807a4e91be89/macports-ports (master):

openssh: fix implicit declaration in gsskex variant

See: #62320

Keywords: catalina bigsur added; openssh removed
Summary: openssh build failureopenssh @8.4p1_1+gsskex: error: implicit declaration of function 'auth_get_canonical_hostname' is invalid in C99

Did that fix it or is there still more to fix?

comment:6 Changed 4 years ago by Schamschula (Marius Schamschula)

It cleanly built on my M1 mini running Big Sur. However, I didn't not test the functionality, as I normally don't install this variant.

comment:7 Changed 4 years ago by vkuznet (Valentin Kuznetsov)

Do you want me to test the functionality? Is it possible to build it on a side such that I'll still keep my existing working port? If so, please send me instructions and I can see how it works. I use GSS authentication to access CERN and FNAL sites.

comment:8 Changed 4 years ago by Schamschula (Marius Schamschula)

Please do! If all is good, we can close this ticket.

comment:9 Changed 4 years ago by vkuznet (Valentin Kuznetsov)

I need a little bit of info, how to apply provided patch and build manually the port in local area? I'm familiar with patching, makefiles, etc., but I never did it within macports workflows. If you have any doc about it this just point me to it.

comment:10 Changed 4 years ago by vkuznet (Valentin Kuznetsov)

I tried the following:

# step 1
cd /tmp
curl -ksLO https://raw.githubusercontent.com/macports/macports-ports/dbf07b3da095588d8578fa663a51807a4e91be89/net/openssh/files/openssh-8.1p1-gsskex-all-20141021-mp-20201216.patch

# step 2, locate port area
port dir openssh
cd /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/net/openssh

# step 3, copy over new patch file
cp openssh-8.1p1-gsskex-all-20141021-mp-20201216.patch openssh-8.1p1-gsskex-all-20141021-mp-20201216.patch.orig
cp /tmp/openssh-8.1p1-gsskex-all-20141021-mp-20201216.patch .

# step 4, build port
sudo port build openssh +gsskex+kerberos5+xauth

The port build fails again with

Again, I'm new to port build workflow and may easily miss something, so I need a little bit of guidance.

The patch needs to be in the net/openssh/files folder. It looks like the original patch (minus the missing #include) was applied.
