In the future, please fill in the Port field and add the port maintainer(s) to Cc (port info --maintainers w3m), if any.

[ryandesign (Ryan Carsten Schmidt)]

Development of w3m seems to have ended years ago. The last release was in 2011 and there are years worth of unanswered bug reports in their issue tracker.

Meanwhile, Debian has a fork that has continued the development. We offer this in the w3m-devel port. Try installing that instead.

If that works, we could potentially try to identify the fix and backport it to the w3m port, although we might want to consider instead switching the w3m port to the Debian fork and getting rid of w3m-devel.

[ryandesign (Ryan Carsten Schmidt)]

Has duplicates #61432 and #61433. Unfortunately it looks like the problem affects w3m-devel as well. Hopefully the developers of w3m-devel can fix it. Probably they should focus on fixing implicit declarations of functions.

I'm trying to upgrade outdated. w3m is not currently installed. But my upgrade is stalled there .. perhaps something being upgraded now requires w3m ?

[arappe]

I'll just chime in briefly. I understand that w3m is obsolete. I think that neomutt is not obsolete however, and neomutt depends on w3m. Is there a way to compile neomutt in MacPorts without w3m available? If so, I'd be happy to learn how. Thanks! (I don't need / use the w3m html-viewing functionality in neomutt. I use lynx for that.)

You can install neomutt without doc to get rid of w3m dependency.

sudo port install neomutt -doc

Hi there - I am trying to install "gimp +quartz". gimp requires w3m, that does not compile as said before; this is an install from scratch, since I upgraded to Big Sur. Does that means that I cannot install gimp +quartz under Big Sur?

[amake (Aaron Madlon-Kay)]

I have several PRs open to remove w3m from the dependency chain of gimp.

• ​https://github.com/macports/macports-ports/pull/9177
• ​https://github.com/macports/macports-ports/pull/9176
• ​https://github.com/macports/macports-ports/pull/9175

Once those are merged, w3m won't be your problem, but py27-gobject is still failing on Big Sur so you still won't have your gimp :(

[kencu (Ken)]

w3m installs fine on BigSur if you build it with macports-clang-9.0:

% sudo port -v install  w3m configure.compiler=macports-clang-9.0

% port -v installed w3m
The following ports are currently installed:
  w3m @0.5.3-38_0 (active) platform='darwin 20' archs='x86_64' date='2020-11-20T15:46:22-0800'

This might get us by until it is fixed up properly.

[kencu (Ken)]

macports-clang-10 works fine too, and is six months newer.

w3m/w3m-devel: build with clang-9.0

temporary fix until this port is updated to build against
newer, stricter clang on BigSur or replaced

[jwoehr (Jack J. Woehr)]

Thanks everyone, the update works for me, at least, I'm past wm3 in upgrading outdated on Big Sur.

[hexadecagram ({16/7})]

Now with the temporary fix in place, port upgrade -u outdated installs w3m but fails as expected once it reaches py27-gobject.

What is the magic formula for bypassing ports that fail to build so that what can be built will be built? I have tried deactivating py27-gobject (and py27-pygtk) yet port still attempts to build them. I have also tried such things as port upgrade -u outdated and not py27-gobject without success.

EDIT: There's probably a more elegant solution but this seems to do the trick: sh -c 'for portname in "$@"; do; sudo port deactivate "$portname" or "rdependentof:$portname"; done' -- py27-gobject

xdg-utils: replace w3m build dependency with links

w3m doesn't build on Big Sur and seems to be abandoned. A text-based browser is
used for generating text files at build time, and links is explicitly suggested
as an option:

`
No way to convert HTML to text found.
Try either installing text web browser(lynx/w3m/links) or use option --with-fop
`

(lynx does not currently build on Big Sur either)

xmlto apparently needs to be told at configure time where the links binary is,
so the dependency on links is pushed into the xmlto port.

[enckse (Sean Enck)]

I mucked around with a PR to update w3m-devel (​https://github.com/macports/macports-ports/pull/11467) but then w3m broke in CI which required me to cherry-pick 2 changes from w3m-devel back to even get it to build. I hesitated to even attempt to fix the build issue because I had previously noticed the above comment/quote:

If that works, we could potentially try to identify the fix and backport it to the w3m port, although we might want to consider instead switching the w3m port to the Debian fork and getting rid of w3m-devel.

and switching the w3m port seems like the real fix to this problem

[p-bro]

I'm having the build of w3m and w3m devel fail on Big Sur (11.6) on arm64 with a different error (both with the same):

:info:build file.c:185:5: error: too few arguments to function call, expected 2, have 1
:info:build     LONGJMP(AbortLoading, 1);
:info:build     ^~~~~~~~~~~~~~~~~~~~~~~~
:info:build ./config.h:185:38: note: expanded from macro 'LONGJMP'
:info:build # define LONGJMP(env,val) longjmp(env)
:info:build                           ~~~~~~~    ^

Symptom of the same bug, or worthy of new bug report?
