viking v1.10 build fails with an error

[svetlemodry]

Hi!
I am attempting to build the viking 1.10 package on Arch Linux and the build is failing for me with an error.
For the build I am using the current PKGBUILD
And here is the output of the build run.
I've tried to search the current issues on github, but did not find anything relevant, hence this report.
I'd be glad for any hints on how to get this sorted out.
Cheers!

It appears to be failing on compiling:
/usr/include/unicode/stringpiece.h

Which comes from libicu-dev package or similar - so what version of libicu is on your system?

See https://icu.unicode.org/ ; so if ICU 75, then needs C++17 - whereas the build for Viking in v1.10 says C++11.

This is co-incidentally solved by https://sourceforge.net/p/viking/bugs/170/

The easiest way to work around it in v1.10, should be by disabling the Mapnik component (but obviously then any usage of the related features won't be available).

./configure --disable-mapnik

Thanks for checking this!

We have icu 75.1-1 in the repository.

Quick try to cherry pick that patch seemed not to fix the build for me.

./configure --disable-mapnik

I went with disabling mapnik for now, package builds again.
Will wait for the new release to enable mapnik again.
Cheers & thanks!
