[ArtKoKo]

wkhtmltopdf has dependencies qt5-qtwebkit but it fails to build

:info:build Command failed: /usr/bin/make -j8 -w 

I have succesfully installed qt5-qtwebkit on Mac OS Big Sur 11.5.2 with Apple Silicon ARM...

qt5-qtwebkit @5.9.2_2 build works with latest ports tree...

         "event.h"

Since -I/opt/local/include is the very first include flag being passed to the compiler (i.e. highest precedence), I would guess /opt/local/include/event.h (from port libevent) is getting picked up instead. A similar case insensitive filesystem issue was encountered in ticket:63877#comment:6.

In 8b528349a8adb591352e8a81ec884764c7bb8e65/macports-ports (master):

qt5-qtwebkit: Fix build for Big Sur, Monterey, and Ventura with header conflicts

On case insensitive file systems, the include search path picks up header files from
macports before the local header files causing an error while compiling. This
modification places flags the known conflicting ports with conflicts_build.

Closes: #63877
Closes: #62027
Closes: #66177
Closes: #63566

to get this installed while a more permanent fix is identified do the following:

sudo port -f deactivate libarchive ruby31 ruby30 libevent
sudo port install qt5-qtwebkit
sudo port -f activate libarchive ruby31 ruby30 libevent

Depending on what is installed on your system, you may need to adjust the deactivate/reactivate commands.
