Description Ionen Wolkens gentoo-dev

2022-09-30 07:52:57 UTC

Created attachment 814771 [details]
build.log + emerge --info.txt

Long list of implicit warnings with gcc that will all be failures here.

Also the y.tab.c kind:

y.tab.c:1172:16: error: call to undeclared function 'yylex'; ISO C99 and later do not support implicit function declarations [-Werror,-Wimplicit-function-declaration]
      yychar = yylex ();

Some ./configure tests are broken too, e.g.

checking for working snprintf... no
checking for working vsnprintf... no
configure: WARNING: Replacing missing/broken (v)snprintf() with version from http://www.ijs.si/software/snprintf/.

Also imake cpp issues, but will fix that bit myself soon which lets it build clang15 without the -Werror=*

    media-libs/nas: force gcc -E for imake's generation
    
    Requires traditional cpp support and is broken in all sort of ways
    with clang-cpp / -E.
    
    Bit messier here because of multilib, hopefully this is right and
    doesn't affect other arches. If multilib support is ever removed,
    replace by ":-${CHOST}-gcc -E}" like other ebuilds.
    
    wrt #873619, this is still severely broken with >=clang16
