Build errors: unknown type name ‘SOUP_AVAILABLE_IN_2_4’; did you mean ‘SOUP_AVAILABLE_IN_3_4’? and rmssdp.c:55:13: error: assignment to ‘const GUri *’ {aka ‘const struct _GUri *’} from incompatible pointer type [...].

Ahoj,

I want to build this (latest git checkout) on Artix GNU/Linux (rolling release).

  • GCC version: 15.1.1.
  • libsoup version: 2.74.3.
  • libsoup3 version: 3.6.5.

Build fails for me with different kind of errors:

  • libsoup-2.4/libsoup/soup-misc.h:14:1: error: unknown type name ‘SOUP_AVAILABLE_IN_2_4’; did you mean ‘SOUP_AVAILABLE_IN_3_4’? etc.:

ninja: build stopped: subcommand failed.

The second one I could workaround by adding -Wno-error=incompatible-pointer-types to $CFLAGS/ $CXXFLAGS environment variable.

The first one I don't know about. Maybe it needs to more specifically use the correct libsoup version, when 2.x and 3.x are both installed?

Regards!
