Package: texlive-bin
Version: 2014.20140926.35254-1
Severity: normal
Tags: patch
User: debian-arm@lists.debian.org
Usertag: arm64
This version of texlive-bin does not build on arm64 due to the
internal libpng trying to use 32-bit neon code (neon is ARM SIMD
unit). The attached simple patch correctly restricts that code to the
right architectures.
There is actually a C intrinsics Neon implemention in the libpng which
could be used for arm64, but that would involve more work, and for an
internal libpng inside texlive does not seem worth the effort,
especially at this stage of the release cycle.
I presume there is a good reason why this package has its own libpng
and is not using the system one (where this issue should already be
fixed)? (or maybe it is but the internal one gets built anyway?)
Anyway, a quick upload with this fix would be appreciated to get
texlive-bin up to date in the arm64 architecture which is currently
planned to be released with Jessie. I'm happy to NMU if you prefer.
thanks for your work with this epic package!
Wookey
