Hi. Those are two different problems. The make failure is due to the lacking of the --std=c++17 flag. I have to define the c++ version in automake.

The meson compilation failure is different, and it seems like it is a libfmt compatibility problem as the compilation doesn't find https://fmt.dev/latest/api.html#_CPPv4N3fmt7runtimeE11string_view. For that we need to figure out how the meson dependencies work.

[gnusupport]

How do I circumvent or solve it before you update it? How do I apply the flag?

libfmt-dev is already the newest version (7.1.3+ds1-5)

I am on Debian stable, and I cannot get it done.

[dov]

I'll have a look. I hope to get to it today.

[gnusupport]

PKG_CONFIG_PATH=/package/lib/fmt/lib/pkgconfig:$PKG_CONFIG_PATH CXXFLAGS="-std=c++17" ./configure --prefix=/package/tools/paps

for now I have installed fresh fmt library and used the above flag to install paps but maybe you could look into it why it cannot be installed direct on Debian.

[dov]

I tried compiling on a bullseye system yesterday, and it compiled without any problem with meson from the HEAD of the git repo. Note however that my meson invocation used the wrap to download a fresh version of libfmt. I have no idea why...

I understand you also used $PKG_CONFIG_PATH

I hope you will incorporate some changes that it goes automatically in future. paps is used on my side for teaching, consulting, it is great tool, but then I changed the system to Debian from Parabola which is based on Arch Linux

[dov]

@gnusupport Is this still an issue?
