Dear All, I want to celebrate the 10th anniversary of this patch https://www.ginac.de/pipermail/ginac-devel/2009-October/001675.html by its re-submission. Since it was not objected since the original submission by anyone, it may be the time now to add this basic calculus-textbook rule to GiNaC. Best wishes, Vladimir -- Vladimir V.

MinGW64 compilation fix
by Alexey Sheplyakov 12 Dec '19

Hi! The attached patch makes GiNaC compile for 64-bit Windows (with GCC compiler). The problem was constructing expressions from std::size_t. On 64-bit Windows std::size_t is unsigned long long (same as uint64_t) and there were no constructors taking long long. Best regards, Alexey

Fixes MinGW64 build. On 64-bit windows std::size_t is `unsigned long long` (64 bit). However there is no ex constructor taking (unsigned) long long. This patch adds ex and numeric constructors taking `long long` and `unsigned long long`. ----------------------------------------------------------------------- Summary of changes: ginac/ex.cpp | 20 +++++++++++++++++++- ginac/ex.h | 16 ++++++++++++++++ ginac/numeric.cpp | 11 +++++++++++ ginac/numeric.h | 2 ++ 4 files changed, 48 insertions(+), 1 deletion(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations
