[Octave-bug-tracker] [bug #57033] Replace CXSPARSE with SPQR

[Simon]

Follow-up Comment #17, bug #57033 (project octave):

I couldn't reproduce the error. I applied the rev6-patch to changeset
8619dc0d3749. My OS is Ubuntu 19.10 and suitesparse-version is 5.4.0, see
following apt-cache-output

Package: libsuitesparse-dev
Architecture: amd64
Version: 1:5.4.0+dfsg-1
Source: suitesparse


If I call "make check RUN_OCTAVE_OPTIONS=-g",  I get this output 

make  check-recursive

make[2]: Entering directory '/home/simon/octave_src/octave/libgnu'

gdb is not started although it is available on my system. Looking at the lines
27415 and 27709 of the makefile didn't help me. I searched the makefile for
the string "RUN_OCTAVE_OPTIONS" and came to the (possibly wrong) conclusion
that "make check RUN_OCTAVE_OPTIONS=-g" executes

../run-octave -g  --no-init-file --silent --no-history -p
/home/simon/octave_src/octave/test/mex
/home/simon/octave_src/octave/test/fntests.m
/home/simon/octave_src/octave/test

inside the test-directory of the Octave-repository. If I execute this command,
gdb starts and the tests in qr.cc-tst and sparse.cc-tst pass without errors. 

I also executed the minimal steps to reproduce the error. But they didn't
cause any problems. 

Can you give me additional information to reproduce the error?
