(Please don't CC arch teams, they're used for keywording and stabilisation, not general bugs.)

Comment 4 Dirk Sondermann 2023-06-17 16:41:00 UTC

This issue is caused by a bug in toolchain.eclass introduced by the "cleanup < GCC 8 debris" commit about a week ago (https://gitweb.gentoo.org/repo/gentoo.git/commit/eclass/toolchain.eclass?id=a606b978be638005c9b832a733d087dbc97ae6d0).

This commit replaces
    cd "${CTARGET}"/libstdc++-v3/doc
    emake doc-man-doxygen
with
    cd "${CTARGET}"/libstdc++-v3/doc
    emake -C "${CTARGET}"/libstdc++-v3/doc doc-man-doxygen
Of course, using both cd and the -C option doesn't work.

As a workaround, it suffices to comment out the cd line in toolchain.eclass.

Thanks, I was suspecting it was related.

I'll fix now.
