sitecopy error: implicit declaration of function 'socket' is invalid in C99

[scrutarius]

Sitecopy is not compiling on the latest Big Sur (11.5.2) on my M1-based iMac. I am guessing it is a neon compatibility, but that is a guess on my part. The log shows the following:

:info:configure checking for strcasecmp... yes
:info:configure checking for signal... yes
:info:configure checking for setvbuf... yes
:info:configure checking for setsockopt... yes
:info:configure checking for stpcpy... yes
:info:configure checking for poll... (cached) no
:info:configure checking for fcntl... yes
:info:configure checking for getsockopt... yes
:info:configure checking whether stpcpy is declared... yes
:info:configure checking for library containing socket... not found
:info:configure configure: error: could not find library containing socket

The later line being the probable cause.

I would add that it does not compile on my intel-based iMac running Catalina 10.15.7 either. I've copied over the binary from another intel-based iMac running Catalina 10.15.7 to this intel-based machine (not the M1!) where it was been working as a temporary fix.

for this kind of build there should be a file called "config.log" that has the actual attempted build commands and output from the tools in it. If you look in there at the part where the socket library testing is happening, you may find the clue you need to solve your issue.

If I tried to fix it, that is exactly where I would start.

As I said, socket is missing. No idea why.

Ah, that turns out to be an easier one.

The newer systems fail on implicit function definitions.

The trick is to find the header that defines the function, and properly add it to the test.

We have fixed this in other ports about 1.2 million times so far :>

Given this port is apparently running configure with "gcc" it looks like it hasn't had any proper attention in some time...

Yike. Last update was 2008

not sure if this one is still worth having in MacPorts any longer -- but I will take a peek if it's easy.

Are you sure there is not something more recent that would work for you?

here you go

sitecopy: allow newer neon versions (​https://github.com/macports/macports-ports/pull/12121)

allows our current neon 31 to satisfy the check
closes: #63457

This is broken again, now that neon is at version 32.

Replying to glennra:

This is broken again, now that neon is at version 32.

That's now filed as #68122.
