Hi,

Upstream patches related to/for lp-solve I mean:

<https://git=2Elibreoffice=2Eorg/core/+/refs/heads/master/external/lpsolve=
/>

In any way you need to teach ccc -fPIE=2E But then I'd wonder why lp-solve=
 in Debian built=2E=2E=2E That one has "just" -fPIC=2E

See salsa=2Edebian=2Eorg/math-team/lp-solve

Regards=20

Rene
