Actually, this is just some of a wall of errors.

This build doesn't actually seem to be using Clang, so you seem to be setting it wrong.

Unset:  ADDR2LINE, AR, ARFLAGS, AS, ASFLAGS, CC, CCLD, CONFIG_SHELL, CPP, CPPFLAGS, CTARGET, CXX, CXXFILT, ELFEDIT, EXTRA_ECONF, F77FLAGS, FC, GCOV, GPROF, INSTALL_MASK, LC_ALL, LD, LEX, LFLAGS, LIBTOOL, LINGUAS, MAKE, MAKEFLAGS, NM, OBJCOPY, OBJDUMP, PORTAGE_BINHOST, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, RANLIB, READELF, RUSTFLAGS, SIZE, STRINGS, STRIP, YACC, YFLAGS

C compiler for the host machine: x86_64-pc-linux-gnu-gcc (gcc 11.2.1 "x86_64-pc-linux-gnu-gcc (Gentoo 11.2.1_p20211127 p0) 11.2.1 20211127")
C linker for the host machine: x86_64-pc-linux-gnu-gcc ld.bfd 2.37

I'm really not sure how to reproduce this.

[Comment 6 John Helmert III 2021-12-30 16:34:35 UTC]

Thanks to sultan and ionen's sleuthing in #gentoo-dev, the problem is caused by libzip being compiled with Clang and Rizin being compiled with GCC (and this issue could probably be exposed by any revdep). It seems that libzip's declaration of _Nullable needs to be changed (sultan's suggestion):

#if defined(__has_feature)
  #if !__has_feature(nullability)
    #define _Nullable
  #endif
#else
  #define _Nullable
#endif

Reassigning to kde@ as it seems to be an issue in libzip and simply exposed by a consumer.

[Comment 7 Andreas Sturmlechner 2021-12-30 16:38:01 UTC]

Sure, whoever wants to fix clang issues, step up.
