#20866: libgcrypt universal install is subtly broken ----------------------------------------+----------------------------------- Reporter: wiml@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 1.8.0 Keywords: libgcrypt gnutls universal | Port: libgcrypt ----------------------------------------+----------------------------------- Building an i386+x86_64 version of libgcrypt seems to result in a broken libgcrypt. My guess is that either BYTES_PER_MPI_LIMB or SIZEOF_UNSIGNED_LONG is being defined inconsistently between configure and compile. The result I noticed is that when gnutls is linked against this libgcrypt it fails miserably in 'make check'. The simplest test case is probably gnutls' "mpi" test, which fails because gcry_mpi_scan is broken: {{{ |<9>| MPI: length: 60 rand:81ef2a9400000000a0f6204e00000000183844c00000000024b2a49a00000000e5c9036d0000000026327e4c000000004d31fc1900000000a92feb98 }}} You'll notice that the random number isn't very random. Further investigation shows that mpi_read_from_buffer() (an internal libgcrypt function) is being passed a valid random buffer, but is returning an mpi with every other 32 bits omitted, as you see. Libgcrypt does some screwy stuff in its headers, things like #defining SIZEOF_UNSIGNED_LONG to a constant instead of simply using sizeof(unsigned long), so I guess it's not surprising it doesn't cross-compile properly. -- Ticket URL: <http://trac.macports.org/ticket/20866> MacPorts <http://www.macports.org/> Ports system for Mac OS
