Package: mpfr
Severity: grave
Howdy Laurent,
My CGAL software no longer runs, since it uses mpfr and libmpfr relies
on an internal symbol __gmp_rand. In 4.1.4 this was a function and
therefore a symbol in libgmp. In 4.2, it is a #define and thus no
symbol.
I'm of two minds on this one. On one hand you might argue that GMP
should change SOVERSION since it has indeed changed interface. On the
other hand, __gmp_rand was never an advertised API. I'm guessing that
MPFR cheats by using gmp-impl.h to get at it. Is there any chance
that MPFR can be adapted to use only the published external API of
GMP?
For the record, here's a test program. Compile with 4.1.4 installed,
then switch to 4.2 and you'll get a run-time link error.
