[Monotone-devel] build failure

[J Decker]

Arch Linux has no package for monotone.
it installs a Botan-1.11(?) as 'Botan'

I tried to link; but it doesn't compele for a variety of c++14
errors... in configure

checking for botan using botan-1.11.pc... yes
checking whether botan is usable... no
configure: *** botan_CFLAGS=-I/usr/include/botan-1.11
configure: *** botan_LIBS=-lbotan-1.11
configure: error: in `/home/d3x0r/addons/srcpit/monotone-1.1':
configure: error: Must be able to compile and link programs against botan.
