CMake improvements
by Alexey Sheplyakov 14 Oct '20

14 Oct '20

Hi! The patchset at https://github.com/asheplyakov/ginac/tree/cmake (git pull git://github.com/asheplyakov/ginac.git cmake) makes it a bit easier to build and use GiNaC with CMake. In particular 1) one can build both GiNaC and CLN in one pass (without having to make install, figure out CFLAGS, LD_LIBRARY_PATH, etc): git clone -b cmake git://github.com/asheplyakov/ginac.git cd ginac git clone -b cmake git://github.com/asheplyakov/cln.git mkdir build && cd build cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo .. make -j4 2) GiNaC can be included as CMake subproject: That is, to compile a program `derivative.cpp` (which uses GiNaC) one can download GiNaC sources into the `ginac` subdirectory (and CLN into ginac/cln subdirectory), and use the following CMakeLists.txt project(derivative) add_subdirectory(ginac) add_executable(derivative derivative.cpp) target_link_libraries(derivative ginac::ginac) # this adds both libraries and includes/defines 3) Targets are exported, so `find_package(ginac REQUIRED 1.7.0)` works "out of the box" (this requires CMake'ified CLN) Best regards, Alexey

upcoming release
by Richard B. Kreckel 11 Oct '20

11 Oct '20

Dear folks, Judging from the considerable number of citations in high-energy preprints, GiNaC's multiple polylogarithms are widely and successfully used in this community. Together with Moriz Walden, Stefan Weinzierl has now prepared routines for computing "elliptic multiple polylogarithms" as the next level of sophistication for computations of this type. The intend is to add these functions to GiNaC in the days ahead and then do a new release. Stefan has been granted write access to the repo on www.ginac.de. Happy hacking! -richy. -- Richard B. Kreckel <https://in.terlu.de/~kreckel/>
