[Octave-bug-tracker] [bug #43003] polyfit error.... 64 bit problem?

[Ceral Paquet]

Follow-up Comment #9, bug #43003 (project octave):

Hi John - thanks for commenting! I probably don't "need" 64 bit but I used to
run into out of memory errors on MATLAB 32-bit with 4Gb RAM. Weirdly enough,
only with sparse matrices as you need the matrix and all the indices to be in
memory at the same time. I sort of abandoned that project but may return to it
with 64 bit.

I think enable-64 is now working on my computer. No prizes, but I simply
commented out the offending lines in dldfun/amd.cc

 //amd_malloc = malloc;
 //amd_free = free;
 //amd_calloc = calloc;
 //amd_realloc = realloc;
 //amd_printf = printf;

and it compiled.

./configure --enable-jit --with-blas=/opt/OpenBLAS/lib/libopenblas.a
--with-lapack=/opt/lapack/lib/liblapack.a LLVM_CONFIG=/usr/bin/llvm-config-3.3
LD_LIBRARY_PATH=/usr/local/lib CPPFLAGS="-I/usr/local/include"
LDFLAGS="-L/usr/local/lib -l:liblapack.a" --enable-64

The make check was working until it got stuck on plotting functions
(permission denied). I logged in as root and it got stuck at legend (same
error) so I abandoned check.
