However, these attempts produced four different versions of gcc-stripped-5.5.0-powerpc64-linux-gnu.tar.xz. At least two of the attempts were performed on two different x86_64-linux systems. The derivation that produced the differing output was: /gnu/store/pygln3lr6qbxcps3kmn3w4bc0d0nlpd3-gcc-stripped-tarball-5.5.0.drv You can build this derivation in a variety of ways, for example: guix build --target=3Dpowerpc64-linux-gnu -e '(@ (gnu packages make-boots= trap) %gcc-bootstrap-tarball)' or just guix build /gnu/store/pygln3lr6qbxcps3kmn3w4bc0d0nlpd3-gcc-stripped-tarba= ll-5.5.0.drv On my x86_64-linux system, twice I tried running "guix build --check" on this derivation, but each time it surprisingly reported no difference. Out of paranoia, I tried deleting its output with "guix gc --delete", and then building it again. The new output was, indeed, identical to the old output. This makes me think that the non-reproducibility is coming from something outside the immediate build logic of the gcc-stripped-tarball-5.5.0.drv derivation itself. I will next try to rebuild everything from scratch again. I will also try to get copies of the differing outputs from the people involved in that email thread, in order to run diffoscope on them. =2D-=20 Chris --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEy/WXVcvn5+/vGD+x3UCaFdgiRp0FAl7WoXcACgkQ3UCaFdgi Rp0twQ//VDfFrWpdAkX4XpGke8c4sT6/W2LbR7N+xl126nbXhcAKjH13SCjgX3vp /Yrik1IlnEhXwPpujU6GXLv7UbjZLBDERMOee0bFpreaq9TQMq2NJQkcoKE4kOSr +ockDEE71tv4ZEjW3hY8funw9uRGoZBcyPYHyIjd0bNYvRAa1x8nuhrXYE5+rRZ2 h/2k5tynQrkMpxUEVQr0XL0OWXhY5VPD9Wwgd3anY/l643RIg2eLTDF1kvnRCdOq OFN+88hWEx3QzPMZ852SSc99XkHRBaboFkrNIquxIU2lsOHiUSwOkT4/NrdOoeW7 +pXgJ2dcUNvI1JHER50NUjHBndqCke1bYUbCll0f9VE7hi1z/V/hut4t7a5uTUXp QP+aLeS9WDDDyFHwYPf6hotjNwCyOE1aBo0LlNpR+nIX4WSDYCzSKIFQFAva84l2 TDRte0rIKcZ/B3xRraGjgFwJBezme8RkOiORNzFpcRzf0y5hCSPvL3cLc8XmsbAl HT8pCdm0b3kSlBNQmUSV+XxnXvpIUDnxernYb7PEYhgWsopyHBgQtfxMqCj/IZtE OXeh/oumsuKZWxDcgbUI81liQPNlrFlXgfsWiUmtBmv56g/jFko+e+IgIIZroGWj iWHVBGz1EMaENBMXpga4g7XMRTXoXO3QB9xGQ34mHsZC007QPwQ= =DG+o -----END PGP SIGNATURE----- --=-=-=--
