What conditions are required for "#define CONFIG_PIPE2" to be set in
build/config-host.h? It prevents building for Haiku as pipe2() doesn't
exist. I didn't see anything in the configure script regarding pipe2.
I also updated my code to the latest in the repository and this issue
just popped up.
CONFIG_PIPE2 is set from meson.build instead of the configure script.
But why is this blocking your build? The only relevant spot is in
util/oslib-posix.c and there is a fallback to the normal pipe() function
there...
I suspect the compilation is succeeding with a warning, but linking is
not successful. The correct fix is anyway to use a linker test, because
a compiler test would not detect a broken system header/library combo,
where the prototype is defined but the function is not included.
