squid4 @4.4 +kerberos does not compile on macOS 10.13 (darwin/17.7.0) with linker error

[TP75]

Unfortunately, squid4 @4.4 +kerberos +openssl does not compile on macOS 10.13 (darwin/17.7.0) with a linker symbol(s) not found for architecture x86_64 error. However, the default squid4 @4.4 i.e. squid4 @4.4 +openssl compiles.

Local MacPorts 2.5.4 test environment /opt/macports-test1 with certain active ports:

• kerberos5 @1.16.2_0
• libedit @20180525-3.1_1
• openssl @1.0.2p_0

Thanks for the good work. Please do not hesitate to request me for more details at your convenience.

Thank you very much for checking the build phase and naturally a good idea. Maybe I get motivated and should contribute to that forum also as I made some experimental changes to both the squid3 and squid4 Portfiles including e.g., libressl-devel successful compiles.

[TP75]

The following workaround compiles without error.

Refering to ​https://bugs.squid-cache.org/show_bug.cgi?id=4903#c5

For now you can probably work around this by using LDFLAGS in your build options, like so:

./configure LDFLAGS="-lresolv"

Adding the configure.ldflags-append "-lresolv" parameter to the kerberos variant section in the squid4 Portfile helps.

Thanks for the support. One may refer to the MacPorts Guide ​5.3.7. Configure Phase Keywords and ​4.6. Local Portfile Repositories for learning how to apply these changes locally.

A build and install is successful. However, both port test and port -vst install fail.

The command port test fails with error: Error: Failed to test squid4: squid4 has no tests turned on. see 'test.run' in portfile(7) as there seem to be no tests available.

Although port -v install succeeds a port -vst install fails with an error:

:info:destroot  /opt/macports-test1/bin/gmkdir -p '/opt/macports-test1/var/macports/build/_usr_local_macports-test1_ports_net_squid4/squid4/work/destroot/opt/macports-test1/share/squid/icons/silk'
:info:destroot /bin/sh: /opt/macports-test1/bin/gmkdir: No such file or directory
:info:destroot make[2]: *** [install-iconDATA] Error 1

I am unsure why there is such a difference between port -v install and port -vst install.

[kencu (Ken)]

port -vst hides any ports that are not specifically listed as dependencies in the Portfile. So it's failing because the port is using gmkdir but not declaring a dependency on coreutils:

$ port provides /opt/local/bin/gmkdir
/opt/local/bin/gmkdir is provided by: coreutils

[TP75]

Thank you for the explanation. Good to know and shows the importance of the port -vst install check.

So the squid4 Portfile lacks a depends_run port:coreutils parameter line if I understand this correctly and according to the MacPorts Guide ​5.4. Dependencies on dependencies to check before phases destroot and install.

I would presume this a general task to all maintainers.

[kencu (Ken)]

it's more a build dep than a run dep AFAIK, so it should be added to the depends_build list.

and then don't forget, try again, and see what comes next.

always clean between attempts.

[jmroot (Joshua Root)]

It builds fine without coreutils, so no.

@TP75 off-topic: your email setup seems to be strangely configured and is sending me a copy of all the notifications you receive from this ticket. So I end up getting two copies of everything, one directly from Trac and one from you.

[kencu (Ken)]

I'll admit I just looked at this:

:info:destroot /bin/sh: /opt/macports-test1/bin/gmkdir: No such file or directory
:info:destroot make[2]: *** [install-iconDATA] Error 1

looks like it needs actual sorting out I guess.

Distribution of copies is the task of the mailing list, I presume?

The addresses of emails from the ticket system copied to my address look like:

From: MacPorts <noreply@macports.org>
Cc: jmr@macports.org, macports-tickets@lists.macports.org, tp75-macports@vosdav.de
Reply-To: macports-dev@lists.macports.org

Maybe you should update your subscription rules?

AFAIK my Trac Preferences on Notifications are just the default this forum provides to new users. However, I am sorry and being a newbie I may have overlooked something.

If instead you truly receive copies from my email server I would highly appreciate if you could send me directly a copy including all the headers.
