Description changed by mhampton:
Old description:
> phcpack uses a different method and different output for 1-variable
> problems, which breaks a lot of the assumptions in the interface. I will
> ask Jan Verschelde if it is possible to harmonize the output, otherwise I
> will add some special-casing code to the interface.
New description:
phcpack uses a different method and different output for 1-variable
problems, which breaks some assumptions in the interface.
Attached patch trac_4411_and_10607_phc_fixes.patch fixes this problem and
a recent change in phcpack output that breaks everything in the interface
if not addressed.
Apply only the patch:
trac_4411_and_10607_phc_fixes.patch
