Error(s) that match a know pattern in addition to what has been reported in the summary:


../mesa-24.2.6/meson.build:1625:14: ERROR: Automatic wrap-based subproject downloading is disabled

But >=dev-libs/expat-2.1.0-r3[${MULTILIB_USEDEP}] is unconditionally in DEPEND and RDEPEND.

Your build log shows

> dev-libs/expat-2.6.4:0 [...] -abi_x86_32 abi_x86_64 -abi_x86_x32 -examples -static-libs -test unicode

So expat is installed without ABI_X86=32.

I don't see how this is possible.

Reassigning to portage.

We would need more information from the reporter to determine if this is a Portage bug or user error.
