--- Begin Message ---Package: libatlas3-base Version: 3.8.4-6 Severity: grave Justification: renders package unusable I have a Core2 machine that doesn't have the latest FMA4 instructions. My understanding that the libatlas3-base package from unstable shouldn't be doing anything fancy and potentially cpu-specific unless the user rebuilds this package themselves. I have the following trivial program: #include <stdio.h> int dgetrf_(int *m, int *n, double *a, int *lda, int *ipiv, int *info); int main(void) { int three = 3; int ipiv[3]; int info; double A[9] = {1,2,5,2,3,4,5,4,3}; dgetrf_(&three, &three, A, &three, ipiv, &info); printf("info: %d\n", info); return 0; } Session that shows the issue, with some useful diagnostics: dima@shorty:/tmp$ gcc-4.7 -llapack -o tst tst.c dima@shorty:/tmp$ ./tst zsh: illegal hardware instruction (core dumped) ./tst dima@shorty:/tmp$ ldd tst linux-vdso.so.1 => (0x00007fff3bbff000) liblapack.so.3 => /usr/lib/liblapack.so.3 (0x00007f3ff4f8e000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f3ff4c07000) libblas.so.3 => /usr/lib/libblas.so.3 (0x00007f3ff453d000) libgfortran.so.3 => /usr/lib/x86_64-linux-gnu/libgfortran.so.3 (0x00007f3ff4227000) libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f3ff4011000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f3ff3df4000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f3ff3b72000) /lib64/ld-linux-x86-64.so.2 (0x00007f3ff5caf000) libquadmath.so.0 => /usr/lib/x86_64-linux-gnu/libquadmath.so.0 (0x00007f3ff393d000) dima@shorty:/tmp$ update-alternatives --display liblapack.so.3 liblapack.so.3 - auto mode link currently points to /usr/lib/atlas-base/atlas/liblapack.so.3 /usr/lib/atlas-base/atlas/liblapack.so.3 - priority 35 slave liblapack.so.3gf: /usr/lib/atlas-base/atlas/liblapack.so.3 /usr/lib/lapack/liblapack.so.3 - priority 10 slave liblapack.so.3gf: /usr/lib/lapack/liblapack.so.3 Current 'best' version is '/usr/lib/atlas-base/atlas/liblapack.so.3'. dima@shorty:/tmp$ dpkg -S /usr/lib/atlas-base/atlas/liblapack.so.3 libatlas3-base: /usr/lib/atlas-base/atlas/liblapack.so.3 dima@shorty:/tmp$ dpkg -l libatlas3-base Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Description +++-=======================-=======================-============================================================== ii libatlas3-base 3.8.4-6 Automatically Tuned Linear Algebra Software, generic shared dima@shorty:/tmp$ gdb tst core GNU gdb (GDB) 7.4.1-debian Copyright (C) 2012 Free Software Foundation, Inc.
