libkiwix FTCBFS for mipsel: undefined reference to `__atomic_fetch_add_8'

[kelson42]

It seems libkiwix 9.4.1 does not compile properly on mips architecture. As we don’t have this architecture in our CI I suspect the problem could still be here with 10.0.0.

See the details on Debian bug report https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1001514

@veloman-yunkan @legoktm This specific has already been reported and fixed in the past, see #371. I wonder we still have it. Does the string “mips” in the Meson file does not match properly the architecture?

Here is the table of reference for the CPU families as detected/reported by Meson: https://mesonbuild.com/Reference-tables.html#cpu-families.

Here are information about Debian MIPS support: https://wiki.debian.org/MIPSPort.

From whatbI can see, the mipsel architecture as labeled by Debian is a 32 bits architecture. Maybe this is/was a bug in Meson, look at mesonbuild/meson#3842.

Debian CI works with Meson 0.61

I believe to understand the problem, there is a confusion between host_system and target_system in the Meson file. https://mesonbuild.com/Cross-compilation.html is really instructive, and actually this error is a common one :)
