Bug 789114 – dev-libs/nss-3.63.1 on ppc: shlibsign: Illegal instruction

• Status: RESOLVED DUPLICATE of bug 764191
• Product: Gentoo Linux

[Description jannis 2021-05-09 19:29:24 UTC]

I'm trying to compile dev-libs/nss-3.63.1 on a ppc 32bit machine (Apple iBook G4, mcpu=7450). Version 3.58-r2 compiled and installed fine, but version 3.63.1 (keyworded as stable) fails during build:
/var/tmp/portage/dev-libs/nss-3.63.1/work/nss-3.63.1/nss-.ppc/cmd/shlibsign/./sign.sh: line 13:  5269 Illegal instruction     "${2}"/shlibsign -v -i "${5}"

Reproducible: Always

You could try 3.64. The changelog states some PPC-specific fixes:

Bugs fixed in NSS 3.64

    Bug 1705286 - Properly detect mips64.
    Bug 1687164 - Introduce NSS_DISABLE_CRYPTO_VSX and disable_crypto_vsx.
    Bug 1698320 - replace __builtin_cpu_supports("vsx") with ppc_crypto_support() for clang.
    Bug 1613235 - Add POWER ChaCha20 stream cipher vector acceleration.

I have the same issue, but when call directly this code:

cpu_flags_ppc_{altivec,vsx} USE flags should be added to this package.

if ! use cpu_flags_ppc_altivec; then
  export NSS_DISABLE_ALTIVEC=1
fi
if ! use cpu_flags_ppc_vsx; then
  export NSS_DISABLE_CRYPTO_VSX=1
fi
