[Pkg-scicomp-devel] Bug#556338: FTBFS with binutils-gold

[Peter Fritzsche]

Source: scotch
Version: 5.1.6.dfsg-1
Severity: minor
User: peter.fritzsche at gmx.de
Usertags: no-add-needed

Tried to build your package and it fails to build with GNU binutils-gold. The
important difference is that --no-add-needed is the default behavior of of GNU
binutils-gold. Please provide all needed libraries to the linker when building
your executables.

Objects inside an .a archive aren't linked yet. This means that you must resolve
their symbols when linking to a program.
