Package: lcalc
Version: 1.23+dfsg-5
Severity: important
Dear Debian science team,
lcalc will FTBFS when pari 2.9.0 is uploaded to Debian.
Please find two patches to fix that.
The first one fixes lcalc to use current function names.
(another way to fix this is to add
#include <pari/pariold.h>
to Lcommandline_elliptic.cc to add back the old names)
The second fixes an API change between pari 2.7 and 2.9.
With theses patches, lcalc should build with both PARI 2.7.6
and 2.9.0.
Cheers,
