Building for ARM chips without NEON fails. Reproducible: Always Steps to Reproduce: 1. armv5tel-gentoo-linux-gnueabi-emerge -v libgcrypt Actual Results: /usr/libexec/gcc/armv5tel-gentoo-linux-gnueabi/ld: ./.libs/libgcrypt.so: undefined reference to `_gcry_sha512_transform_armv7_neon' collect2: error: ld returned 1 exit status Expected Results: It should build and install. I sent the attached patch upstream to fix the issue. It would need to be backported. However, I think the ebuild could probably also add the CPU USE flag to disable building optional NEON support, since this CPU will never use NEON. The configure summary has the following when the option is not specified. Try using ARM NEON: yes This ebuild change fixes that. --- dev-libs/libgcrypt/libgcrypt-1.9.0.ebuild +++ dev-libs/libgcrypt/libgcrypt-1.9.0.ebuild @@ -12,7 +12,7 @@ LICENSE="LGPL-2.1 MIT" SLOT="0/20" # subslot = soname major version KEYWORDS="~alpha amd64 arm arm64 ~hppa ~ia64 ~m68k ~mips ~ppc ~ppc64 ~riscv ~s390 ~sparc x86 ~amd64-linux ~x86-linux ~ppc-macos ~x64-macos ~sparc-solaris ~sparc64-solaris ~x64-solaris ~x86-solaris" -IUSE="doc o-flag-munging static-libs" +IUSE="cpu_flags_arm_neon doc o-flag-munging static-libs" RDEPEND=">=dev-libs/libgpg-error-1.25[${MULTILIB_USEDEP}]" DEPEND="${RDEPEND}" @@ -55,6 +55,8 @@ $([[ ${CHOST} == *86*-darwin* ]] && echo "--disable-asm") $([[ ${CHOST} == sparcv9-*-solaris* ]] && echo "--disable-asm") + $(use_enable cpu_flags_arm_neon neon-support) + GPG_ERROR_CONFIG="${EROOT}/usr/bin/${CHOST}-gpg-error-config" ) ECONF_SOURCE="${S}" econf "${myeconfargs[@]}" \

Thanks. Ran into this today. Devs appear to have added a somewhat shorter USE flag to control this. Compiling with USE="-asm" allowed libgcrypt to complete.
Upstream has pushed the fix commit, and they are working on a 1.9.1 release with it.

Note that the mask on 1.9.0 currently forces a downgrade to the safe 1.8.x series.
