Description Lukas Lihotzki 2014-10-12 16:41:01 UTC
libsanitizer requires wordexp. Therefore gcc has to be configured with --disable-libsanitizer if uclibc is configured without UCLIBC_HAS_WORDEXP.
By default, UCLIBC_HAS_WORDEXP is disabled.

Reproducible: Always




As a workaround, you can use package.env to disable libsanitizer for all uclibc toolchains:
cross-*-uclibc*/gcc no-wordexp-gcc.conf

env/no-wordexp-gcc.conf
EXTRA_ECONF="--disable-libsanitizer"

i've made the sanitizer library a USE=sanitize flag.  you can disable that when your C library setup lacks functionality it needs.

I don't think it makes a good default:

+       tc_version_is_at_least 4.8 && IUSE_DEF+=( sanitize )
