I am filing this bug as a sanity check before I adjust ebuilds that currently set BDEPEND="virtual/pkgconfg[${MULTILIB_USEDEP}]". When building packages using cross-emerge from crossdev, we have the following scenario: / has MULTILIB_ABIS that correspond to CBUILD/CHOST. On an amd64 system, MULTLIB_ABIS may contain some combination of amd64, x32, and x86. /usr/${CTARGET} has MULTILIB_ABIS that correspond to CTARGET. Taking riscv as an example, it may contain some combination of lp64 and lp64d. If we try to use MULTILIB_USEDEP in a BDEPEND-class dependency when cross-compiling in /usr/${CTARGET}, we end up with something like this: BDEPEND="virtual/pkgconfig[abi_riscv_lp64,abi_riscv_lp64d]" This can never be satisfied because the CBUILD system will have something like the following installed: virtual/pkgconfig[abi_x86_64,abi_x86_x32,abi_x86_32] Here's a real example: > naomi ~ # riscv64-unknown-linux-gnu-emerge -av1 sys-apps/systemd > > These are the packages that would be merged, in order: > > Calculating dependencies... done! > > emerge: there are no ebuilds to satisfy > "virtual/pkgconfig[abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_riscv_lp64d(-)?,abi_riscv_lp64(-)?,abi_s390_32(-)?,abi_s390_64(-)?]". > (dependency required by "sys-apps/systemd-245-r5::gentoo" [ebuild]) > (dependency required by "sys-apps/systemd" [argument]) A workaround is to add virtual/pkgconfig-1 to /etc/portage/profile/package.provided. The only solution I can think of is to ban MULTILIB_USEDEP in BDEPEND.
I need to think about this a bit more but I always thought pkgconfig's use of multilib was a bit weird. We don't apply the same logic under crossdev. I wonder whether it should simply have a forced multilib flag instead like glibc does.
I guess it's not really important for pkgconfig. Have you grepped for other cases of MULTILIB_USEDEP in BDEPEND?
Some packages install ${CHOST}-*config scripts. Some examples: x86_64-pc-linux-gnu-cups-config x86_64-pc-linux-gnu-curl-config x86_64-pc-linux-gnu-gpg-error-config x86_64-pc-linux-gnu-icu-config x86_64-pc-linux-gnu-krb5-config x86_64-pc-linux-gnu-libgcrypt-config x86_64-pc-linux-gnu-mariadb_config x86_64-pc-linux-gnu-mysql_config x86_64-pc-linux-gnu-nspr-config x86_64-pc-linux-gnu-nss-config x86_64-pc-linux-gnu-pcre-config x86_64-pc-linux-gnu-pcre2-config x86_64-pc-linux-gnu-xml2-config x86_64-pc-linux-gnu-xslt-config If such scripts are used, then dependency with [${MULTILIB_USEDEP}] in BDEPEND seems valid.
I don't think MULTILIB_USEDEP in BDEPEND makes sense. For pkg-config, in a cross-emerge setting, it will/should have variables set to point at $SYSROOT properly so that non chost-prefixed pkg-config will just work. IIRC crossdev wrappers merely do that so maybe it's time to promote those variables to an eapi or at least an eclass. In any case, $MULTILIB_USEDEP is not needed there, but maybe pkg-config should be treated more like glibc indeed. For $CHOST-config scripts, you won't have them with multilib as they would be non-native. Such scripts are a PITA in a cross compile setting, but if you must use them, then I would put the dep in DEPEND and have it run the script from $SYSROOT. I think there are a few examples in the tree doing that already, but that also implies those -config scripts *must* be real scripts; that won't work with llvm-config for example (and I never managed to find a proper way to use that for cross compiling).

From what I can tell, those scripts generally emit settings that are specific to CHOST, not CBUILD. In that case, they belong in DEPEND, not BDEPEND.
If I could get some eyeballs on https://github.com/gentoo/gentoo/pull/16025, that would be lovely.
