[Pkg-electronics-devel] Bug#984677: ngspice: Please mark symbols optimized away with -O3 as optional

[Logan Rosen]

Package: ngspice
Version: 34+ds-1
Severity: normal
Tags: patch

Hi,

ngspice 34+ds-1 failed to build on ppc64el in Ubuntu [1] because we use -O3
by default on that architecture, and two symbols are optimized away at
that level.

In Ubuntu, the attached patch was applied to achieve the following:

  * d/libngspice0.symbols: Mark a couple of symbols as optional that are
    optimized away with -O3 on ppc64el.

Thanks for considering the patch.

Logan
