Extcalc installation

I was trying to install extcalc from AUR (yay command), but I got this error:

[ 46%] Building CXX object CMakeFiles/extcalc.dir/src/extcalc.o
/home/redwarf/.cache/yay/extcalc/src/extcalc-0.9.3-1/src/extcalc.cpp: In member function ‘void MainObject::editMenuSlot(int)’:

Why it doesn't works? What could be a solution?

Re: Extcalc installation

1) please use code brackets for your terminal.output. have a look at bbcode.
2) either you find a way to disable this warning (use different flags or a different compiler) or
3) this needs to be fixed upstream.

Re: Extcalc installation

Please consider using an alternative project that is maintained both upstream and on AUR. Please see https://aur.archlinux.org/packages/extc … ent-888204 which you can implement by adding to line 16 of the PKGBUILD which already adjusts CXXFLAGS. diff of change:

diff --git a/PKGBUILD b/PKGBUILD
index 871a37c..7992f41 100644

+++ b/PKGBUILD

If instead you want to address the cause of the issue. You could apply a patch such as:

Re: Extcalc installation

redwarf have you made any progress with finding an alternative to extcalc or applying the suggestions to allow you to build the package?
